A new 3D computer modelling system may significantly improve a surgeon
Patients who have lower extremity proximal deep vein thrombosis (LE-DVT), or a blood clot in their leg, are increasingly undergoing minimally invasive catheter-based blood clot removal
Researchers at Thomas Jefferson University showed that a simple questionnaire, evaluation and pulse-oximetry monitoring can lead to early detection of sleep apnea in patients hospitalized for congestive heart failure (CHF).
ESC Guidelines published on infective endocarditis boost the role of imaging in diagnosis of this deadly disease.
Gestational diabetes is one of the most common conditions that can occur during pregnancy. Although the symptoms generally disappear after delivery, women suffering from gestational diabetes are at increased risk of developing postpartum diabetes in the following years. Researchers at the Helmholtz Zentrum M
Researchers at Case Western Reserve University have developed a magnetic resonance imaging (MRI) contrast agent that detects much smaller aggressive breast cancer tumours and micrometastases than current agents can identify.
The first prototype ultrasound sensors for a new improved breast screening technique have been developed as part of an Innovate UK funded collaboration between the National Physical Laboratory (NPL), University Hospitals Bristol (UHB), North Bristol NHS Trust (NBT), Precision Acoustics Ltd and Designworks. The team is now looking for commercial partners to translate the novel development into a clinical device.
NHS breast cancer screening in England is currently conducted using X-ray mammography, and further investigations may involve a clinical examination, more X-ray mammograms and conventional ultrasound.
During mammography, each breast is compressed between the two plates of an X-ray machine, which some women find very uncomfortable, and two X-rays are taken at different angles. However, the inability of 2D X-ray mammography to separate overlying tissue can lead to false positives and false negatives, and the hazards associated with ionizing radiation limit the frequency with which X-rays can be performed. Conventional ultrasound is highly operator-dependent and suffers from imaging problems, making cancerous tissue difficult to distinguish from healthy tissue.
NPL, UHB, NBT, Precision Acoustics and Designworks are developing a prototype clinical system for a new breast screening technique – using ultrasound computed tomography (UCT) – that may overcome the problems of diagnosing breast disease using conventional X-ray mammography and ultrasound scans. The new ultrasound method will be safer and lower cost than currently-used screening techniques, and the results should be easier for clinicians to interpret.
NPL has developed and patented a novel detection method employing pyroelectric sensors, which convert ultrasonic energy into heat, generating electrical signals which are eventually used to form the ultrasound image. These large-area thermal sensors should generate far fewer image artefacts than conventional piezoelectric detectors, which are sensitive to the phase of the arriving ultrasound waves.

Investigators at The Feinstein Institute for Medical Research have discovered that brain scans can be used to predict patients
MRI scans and other tools to detect and diagnose dementia are helpful but not definitive
Conducted by Adexsol among 754 healthcare professionals (514 radiologists and 240 pediatricians), this survey provides for the first time, data on the medical imaging offer for children.
Pediatric imaging diagnosis waiting times seem long, especially for MRI and to a lesser extent for the CT Scan, according to the survey, published during the French Radiology Days (JFR) in Paris last October.
Results show pediatricians usually refer children to ambulatory radiologists for general imaging
