EXPLORER, the world’s first medical imaging scanner that can capture a 3D picture of the whole human body at once, has produced its first scans. The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined positron emission tomography (PET) and X-ray computed tomography (CT) scanner that can image the entire body at the same time. Because the machine captures radiation far more efficiently than other scanners, EXPLORER can produce an image in as little as 1 second and, over time, produce movies that can track specially tagged drugs as they move around the entire body. The developers expect the technology will have countless applications, from improving diagnostics to tracking disease progression to researching new drug therapies. The scanner has been developed in partnership with Shanghai-based United Imaging Healthcare (UIH), which built the system based on its latest technology platform and will eventually manufacture the devices for the broader health care market. “While I had imagined what the images would look like for years, nothing prepared me for the incredible detail we could see on that first scan,” said Cherry, distinguished professor in the UC Davis Department of Biomedical Engineering. “While there is still a lot of careful analysis to do, I think we already know that EXPLORER is delivering roughly what we had promised. Badawi, chief of nuclear medicine at UC Davis Health and vice chair for research in the Department of Radiology, said he was dumbfounded when he saw the first images, which were acquired in collaboration with UIH and the Department of Nuclear Medicine at the Zhongshan Hospital in Shanghai. “The level of detail was astonishing, especially once we got the reconstruction method a bit more optimized,” he said. “We could see features that you just don’t see on regular PET scans. And the dynamic sequence showing the radiotracer moving around the body in three dimensions over time was, frankly, mind-blowing. There is no other device that can obtain data like this in humans, so this is truly novel.” Badawi and Cherry first conceptualized a total-body scanner 13 years ago. Their idea was kickstarted in 2011 with a $1.5 million grant from the National Cancer Institute, which allowed them to establish a wide-ranging consortium of researchers and other collaborators. And it got a giant boost in 2015 with a $15.5 million grant from the National Institutes of Health. The funding allowed them to team up with a commercial partner and get the first EXPLORER scanner built. Cherry said he expects EXPLORER will have a profound impact on clinical research and patient care because it produces higher-quality diagnostic PET scans than have ever been possible. EXPLORER also scans up to 40 times faster than current PET scans and can produce a diagnostic scan of the whole body in as little as 20 to 30 seconds. Alternatively, EXPLORER can scan with a radiation dose up to 40 times less than a current PET scan, opening new avenues of research and making it feasible to conduct many repeated studies in an individual, or dramatically reduce the dose in paediatric studies, where controlling cumulative radiation dose is particularly important.

Rapid whole-genome sequencing (WGS) of acutely ill neonatal intensive care unit (NICU) patients in the first few days of life yields clinically useful diagnoses in many cases, and results in lower aggregate costs than the current standard of care, according to recent findings. Shimul Chowdhury, PhD, FACMG, Clinical Laboratory Director at the Rady Children’s Institute for Genomic Medicine, and his colleagues focused their analysis on a broad swath of NICU patients for whom a genetic diagnosis might help inform treatment decisions and disease management. They studied the clinical utility and cost-effectiveness of sequencing infants and their parents. “Newborns often don’t fit traditional methods of diagnosis, as they may present with non-specific symptoms or display different signs from older children,” said Dr. Chowdhury. In many such cases, he explained, sequencing can pinpoint the cause of illness, yielding a diagnosis that allows doctors to modify inpatient treatment and resulting in dramatically improved medical outcomes in both the short and long term. Because of the potential for early intervention and immediate adjustment in care, the researchers used a rapid WGS procedure that took three to seven days from sample collection to delivering results to patients’ families. The process can be further accelerated if medically necessary. In contrast, most clinical diagnostic tests take four to six weeks. In 34 (35%) of the 98 patients enrolled in the study, WGS yielded a genetic diagnosis, and in 28 (80%) of those patients, that diagnosis led to changes in medical management, such as the use of medications targeted to the underlying disease, avoidance of unnecessary surgery, and guidance about palliative care. Cost-effectiveness analyses are ongoing, but among the first 42 infants sequenced, the researchers calculated a $1.3 million net cost savings for that hospitalization versus the current standard of care. “The cost savings were especially striking, given that sequencing costs are still high – even with those costs, we found that rapid WGS was not just clinically useful but economically prudent,” Dr. Chowdhury said. Currently, the researchers are looking to expand their study and assess the effectiveness of their approach across health systems and populations. Ongoing partnerships with children’s hospitals in California and Minnesota involve scaling up the rapid WGS process to meet demand and yield new insights about its clinical utility, cost-effectiveness, and ease of implementation in different environments. Dr. Chowdhury noted the important contribution of genetics research to their progress so far. “Translational research leading to improvements in the speed and accuracy of sequencing tests is so important to our work, and has a real impact on patients and their families,” he said.

When a patient arrives in any emergency department, one of the first steps in their care process is triage, an opportunity for a care team member to identify critically ill patients and assign priority treatment levels. “With increases in annual visits to U.S. emergency departments, declines in capacity have led to unprecedented levels of crowding and consequential delays in care,” says Scott Levin, Ph.D., associate professor of emergency medicine at the Johns Hopkins University School of Medicine. “So what emergency departments have to do is very quickly assess whether a patient is in need of real critical, time-sensitive treatment versus a patient who is safe to wait.” Across the country, nurses and physicians typically use the emergency severity index (ESI) during triage to assign a score from Level 1 for patients who are the most critically sick, to Level 5 for patients who are the least sick. A patient’s ESI level determines in which area of the emergency department that patient will be seen, places the patient in a queue and influences provider decision-making throughout the patient’s care process. “This algorithm is completely subjective,” Levin says. “Nurses and physicians make a quick assessment on whether the patient can wait solely based on their clinical judgment.” In most cases, researchers say patients are assigned to a Level 3 and not entirely differentiated. “We thought that Level 3 patient group included a large mix of patients who are pretty sick and others who weren’t, and our goal was to determine whether these patients could be sorted out,” Levin says. To help differentiate patient triage levels, Levin and a team in the Department of Emergency Medicine developed an electronic triage tool. In a recently published paper the e-triage tool showed equal or improved identification of patient outcomes compared to ESI based on a multi-site retrospective study of nearly 173,000 emergency department visits. The study showed significant differences in patient priority levels using e-triage and ESI. For example, out of the more than 65 percent of visits triaged to ESI Level 3, e-triage identified about 10 percent, or more than 14,000, ESI Level 3 patients who may have benefitted from being up-triaged to a more critical priority level, such as Level 1 or 2. These patients were at least five times more likely to experience a critical outcome, such as death, admission to the ICU or emergency surgery, and two times more likely to be admitted to the hospital. The e-triage tool was also able to increase the number of patients down-triaged to a lower priority level, such as Level 4 or 5, to help minimize low-acuity patients from waiting and overusing scarce resources. The e-triage tool uses an algorithm to predict patient outcomes based on a systems engineering approach and advanced machine learning methods to identify relationships between predictive data and patient outcomes. “When a patient comes in, and we collect the patient’s information, the e-triage tool is comparing that patient to hundreds of other like patients to make a prediction on the patient’s outcome,” Levin says. These methods are common in other industries, such as defence, transportation and finance, but rarely, if ever, are implemented in healthcare. “Machine-based learning takes full advantage of electronic health records and allows a precision of outcomes not previously realizable,” says Gabor Kelen, M.D., director of the Department of Emergency Medicine and professor of emergency medicine at the Johns Hopkins University School of Medicine. “It is the wave of future healthcare, although some providers may be hesitant. Decision aids that take advantage of machine-learning are also highly customizable to meet the needs of an emergency department’s patient population and local healthcare delivery systems.” The e-triage tool is also designed to be a decision support tool to help clinicians make better care decisions about their patients. “The theory behind this tool, and all clinical decision support tools, is that the tool paired with the clinician can make better predictions or better prognostics tasks like this than the tool alone or the clinician alone,” Levin says. Better differentiating patients’ priority levels, can, in turn, help patients get the appropriate care they need. “The ultimate objective is patients should be waiting less in the emergency department,” Levin says. “For patients at risk of having a critical care need, this technology is designed to detect them better and make sure they are seen quicker. For patients who are less sick, e-triage should detect those patients and put them on an expedited track, so they don’t need to wait as long.”

Researchers from MIT and Massachusetts General Hospital (MGH) have developed a predictive model that could guide clinicians in deciding when to give potentially life-saving drugs to patients being treated for sepsis in the emergency room. Sepsis is one of the most frequent causes of admission, and one of the most common causes of death, in the intensive care unit. But the vast majority of these patients first come in through the ER. Treatment usually begins with antibiotics and intravenous fluids, a couple litres at a time. If patients don’t respond well, they may go into septic shock, where their blood pressure drops dangerously low and organs fail. Then it’s often off to the ICU, where clinicians may reduce or stop the fluids and begin vasopressor medications such as norepinephrine and dopamine, to raise and maintain the patient’s blood pressure. That’s where things can get tricky. Administering fluids for too long may not be useful and could even cause organ damage, so early vasopressor intervention may be beneficial. In fact, early vasopressor administration has been linked to improved mortality in septic shock. On the other hand, administering vasopressors too early, or when not needed, carries its own negative health consequences, such as heart arrhythmias and cell damage. But there’s no clear-cut answer on when to make this transition; clinicians typically must closely monitor the patient’s blood pressure and other symptoms, and then make a judgment call. In a paper, researchers describe a model that “learns” from health data on emergency-care sepsis patients and predicts whether a patient will need vasopressors within the next few hours. For the study, the researchers compiled the first-ever dataset of its kind for ER sepsis patients. In testing, the model could predict a need for a vasopressor more than 80 percent of the time. Early prediction could, among other things, prevent an unnecessary ICU stay for a patient that doesn’t need vasopressors, or start early preparation for the ICU for a patient that does, the researchers say. “It’s important to have good discriminating ability between who needs vasopressors and who doesn’t [in the ER],” says first author Varesh Prasad, a PhD student in the Harvard-MIT Program in Health Sciences and Technology. “We can predict within a couple of hours if a patient needs vasopressors. If, in that time, patients got three litres of IV fluid, that might be excessive. If we knew in advance those litres weren’t going to help anyway, they could have started on vasopressors earlier.” In a clinical setting, the model could be implemented in a bedside monitor, for example, that tracks patients and sends alerts to clinicians in the often-hectic ER about when to start vasopressors and reduce fluids. “This model would be a vigilance or surveillance system working in the background,” says co-author Thomas Heldt, the W. M. Keck Career Development Professor in the MIT Institute of Medical Engineering and Science. “There are many cases of sepsis that [clinicians] clearly understand, or don’t need any support with. The patients might be so sick at initial presentation that the physicians know exactly what to do. But there’s also a ‘gray zone,’ where these kinds of tools become very important.”

A team of University of Illinois at Urbana-Champaign researchers led by Bioengineering Professor Stephen Boppart has successfully visualized the tumour microenvironment of human breast tissue shortly after it was surgically removed from a patient in the operating room. The researchers achieved this using a new portable optical imaging system developed in Boppart’s lab. This work marks a major step toward providing cancer researchers with a new tool for tracking tumour progression and physicians new technology for tissue pathology and diagnostics. Typically, the process for diagnosing cancer takes several days. A surgeon first removes a tissue sample that is then processed with chemical dyes; later, the sample is sent to a pathologist for examination and subsequent diagnosis. Label-free intraoperative nonlinear imaging of the tumour microenvironment provides real-time visualization of structural and molecular features, including extracellular vesicles that can be potential biomarkers of cancer aggressiveness. "We believe that capturing the dynamic cellular and molecular features in freshly removed or biopsied tissue specimens contains valuable diagnostic and prognostic information that is currently lost when specimens are placed in a fixative and essentially killed quickly in order to preserve structure," said Boppart, who is also a faculty member at the Beckman Institute for Advanced Science and Technology at Illinois and a professor of electrical & computer engineering (ECE) and the Carle Illinois College of Medicine. "Our imaging platform and methodology allow us to extract this new information in real-time, at the point-of-procedure." Boppart’s portable optical imaging system uses precise light pulses to simultaneously image tissue in four modalities, enabling his team to study concurrent processes within cells and tissue that make up the tumour microenvironment. For example, collagen fibres appear in green; elastin fibres and flavin adenine dinucleotide-containing cell cytoplasm appear in yellow; cell membranes, lipid boundaries, and extracellular vesicles (EVs) appear in magenta; and nicotinamide adenine dinucleotide in the cells and lipids appears in cyan. The team demonstrated the viability of their imaging system in the operating room at Carle Foundation Hospital during breast cancer surgeries. Within 30 minutes of the diseased tissue being extracted, the researchers were able to identify specific tissue features, including molecular signatures associated with metabolic activity inside individual cells that make up the tumour microenvironment. The researchers were also interested in measuring tumour-related extracellular vesicles (EVs), which are known to promote the spread of cancer. "EVs do play an essential role in cancer progression," said ECE graduate student Yi "Edwin" Sun, the lead author of the research paper. "Quantifying EV densities may be developed as a potential biomarker for future cancer diagnoses." As part of their studies, they also collected and imaged healthy breast tissue that surgeons had removed from cancer-free patients during breast reduction procedures. In a comparison of the two types of tissue, they found a clear difference in EV density between the cancerous and healthy tissue. For example, the cancerous tissue exhibited increased EV densities and had shorter tumour-to-margin distance. "What we observed about the extracellular vesicles is significant but it could only be accurately determined with our new system," said Sun, noting how other portable optical imaging systems deployed in the operating room all alter the tissue samples either with fluorescent dyes or toxic ultraviolet light. "Our imaging technique works well with current cancer treatment routines and is free of any form of perturbation." According to Boppart, the team’s future plans include using the imaging system on tissue specimens obtained from needle-biopsy procedures that are routinely performed in outpatient settings. They will also continue using the system on samples from the operating room.

Researchers have reported an approach to photoacoustic imaging that offers vastly improved resolution, setting the stage for detailed in vivo imaging of deep tissue. The technique is based on computational improvements, so it can be performed with existing imaging hardware, and thus could provide a practical and low-cost option for improving biomedical imaging for research and diagnostics. After further refinements, the approach could offer the opportunity to observe the minute details of processes occurring in living tissue, such as the growth of tiny blood vessels, and therefore provide insights on normal development or disease processes such as cancer. “Our main goal is to develop a microscope that can see the microvasculature and capillary vessels,” said Ori Katz, a researcher with the Hebrew University of Jerusalem, Israel, and senior author of the study. “It’s important to be able to watch these grow with nearby tumours, for example.” The researchers describe overcoming the acoustic diffraction limit, a barrier that previously limited the resolution obtainable with photoacoustic imaging, by exploiting signal fluctuations stemming from the natural motion of red blood cells. Such fluctuations might otherwise be considered noise or viewed as detrimental to the measurements. “With photoacoustic imaging you can see much deeper in tissue than you can with an optical microscope, but the resolution is limited by the acoustic wavelength,” Katz said. “What we have discovered is a way to obtain photoacoustic images with considerably better resolution, without any change in the hardware.” Photoacoustic imaging combines optical illumination (which uses light waves) and ultrasound (which uses sound waves) to image biological samples in ways that would not be possible with either modality alone. Optical methods can provide excellent resolution but often only near the surface as light is highly scattered in tissue. Ultrasound can go much deeper but does not offer the same contrast as optical imaging. By integrating the two modalities, researchers have been able to overcome the drawbacks of each to advance a host of applications. However, the imaging technique does have certain limitations. Photoacoustic imaging relies on acoustic detection, so the image resolution is determined by the acoustic wavelength. While optical microscopy, for example, can see objects on the scale of less than a micron, photoacoustic imaging is limited to tens of microns. This means that photoacoustic imaging cannot resolve small objects like microvessels or capillaries. Katz devised the method for surpassing the acoustic diffraction limit in collaboration with Emmanuel Bossy, now at Université Grenoble Alpes in Grenoble, France. At the heart of their work is an advanced statistical analysis framework that they apply to images of red blood cells flowing through the vessels; the blood cells facilitate imaging by absorbing light at particular wavelengths. By increasing the resolution computationally, they avoided the need for any additional hardware, so the advances described can be attained using existing photoacoustic imaging systems. The tools needed to achieve super-resolution with photoacoustic imaging were described nearly a decade ago in a work in optical microscopy with the technique of super-resolution optical fluctuation imaging (SOFI). Katz and colleagues came to this work after grappling with the problem of the acoustic diffraction limit and discovered that the same mathematics used with SOFI could be used for improving photoacoustic imaging. “Someone just needed to make the connection,” Katz said. “It’s the same equation—the wave equation. Mathematically, you could say it’s the same problem.” Katz and his colleagues demonstrated the ability to surpass the acoustic diffraction limit using a SOFI-inspired photoacoustic imaging technique. That work had two main limitations. First, it required the use of a long-coherence laser, not a standard part of photoacoustic imaging systems, in order to form dynamic structured interference patterns called speckle to create the signal fluctuations. Second, due to their small dimensions, the use of speckles as dynamic illumination resulted in the fluctuations having a low amplitude with respect to the mean photoacoustic signal, which in turn made it difficult to resolve the specimen in question. In the new study, the researchers showed that they could overcome these limitations by applying the statistical analysis framework to the inherent signal fluctuations caused by the flow of red blood cells—so the researchers didn’t need to rely on coherent structured illumination—and furthermore demonstrated experimentally that they could perform super-resolution photoacoustic imaging using a conventional imaging system. The demonstration served as a proof of principle for the new technique. The researchers are now focused on developing it further, to fulfill its potential for in vivo applications. Katz described two main challenges in reaching this goal. The first is the problem of motion artifacts. In their demonstration, the researchers imaged blood streaming through small tubes. In animal models and in humans, though, blood flow is only one of the motions they would have to consider. The technique would also need to account for the heartbeat, the changing volume of the vessels and even microscale movements of the tissue itself. The other main challenge relates to signal levels. In recent experiments blood was the only absorber in play, but in real-world scenarios other absorbers would be present. The researchers are now working on ways to better see the signal originating from flow while suppressing any background signals.

Researchers have shown that a new nuclear medicine procedure could safely and more effectively detect cancerous gastrointestinal and pancreatic neuroendocrine tumours than current methods. Neuroendocrine tumours (NETs) can occur in almost any organ, but they are most commonly observed in the pancreas and gastrointestinal tract. The average time until diagnosis is 3 to 10 years. An estimated 40 to 95 percent of cancerous gastroenteropancreatic NETs (GEP-NETs) have spread to other parts of the body (metastasized) by the time of diagnosis. Most GEP-NETs express a high density of somatostatin receptor subtype 2 (sst2). These receptors have, therefore, become a prime target for imaging and treating these tumours. Currently, gallium-68 (68Ga)-DOTATOC/-TATE for diagnostic imaging and lutetium-177 (177Lu)-DOTATOC/-TATE for therapy are paired for “theranostic” identification and treatment of NETs. Preclinical and preliminary clinical evidence indicates that the novel radiolabeled tracer 68Ga-OPS202, an sst antagonist with a high affinity for sst2, has the potential to perform better than an sst agonist such as 68Ga-DOTATOC because 68Ga-OPS202 binds to more sst receptor binding sites than sst agonists. This first-in-human Phase 1/2 study, included 12 patients with well differentiated GEP-NETs. Based on total numbers of detected malignant lesions, the optimal time window for the scan was determined to be between 1 and 2 hours. The study shows that 68Ga-OPS202 is rapidly cleared from the blood, resulting in low background activity, especially in the liver and gastrointestinal tract. “Even though the effective dose of 68Ga-OPS202 is comparable to other 68Ga-labeled somatostatin analogs, there are striking differences concerning its biodistribution and organ doses such as liver, gastrointestinal tract, pancreas, lung and spleen,” explains Damian Wild, MD, PhD, University Hospital Basel in Basel, Switzerland. He points out, “The lower organ doses and tracer uptake of 68Ga-OPS202, especially in the gastrointestinal tract and the liver, is clinically relevant, as it allows improvement of the imaging contrast (tumour-to-background ratios) and sensitivity for detecting primary tumour or liver metastases of GEP-NETs (as shown in comparison to 68Ga-DOTATOC in Phase 2 of the study, also published in the June JNM). Important for patients is that 68Ga-OPS202 was well tolerated and did not raise any safety concerns.” Wild states, “68Ga-OPS202 could be a favourable alternative to the current radiolabeled somatostatin agonists in use in the clinic for PET/CT imaging of neuroendocrine tumour patients. In addition, due to their enhanced binding properties, radiolabeled sst antagonists may open a new avenue for PET imaging and targeted radionuclide therapy in non-neuroendocrine tumour indications. In that sense 68Ga-OPS202 is the ideal theranostic companion for 177Lu-OPS201 targeted radionuclide therapy.”
