Super-fast MRI scan could revolutionise heart failure diagnosis<\/h1>Cardiology<\/a><\/span>, MRI<\/a><\/span>, Featured Articles<\/a> <\/span><\/span><\/header>\n<\/div><\/section>

Researchers at the University of East Anglia have developed cutting-edge technology to diagnose patients with heart failure in record time. The state-of-the-art technology uses magnetic resonance imaging (MRI) to create detailed 4D flow images of the heart. How-ever, unlike a standard MRI scan, which can take up to 20 minutes or more, the new 4D heart MRI scan takes just eight minutes.<\/strong><\/p>\n

The results provide a precise image of the heart valves and blood flow inside the heart, helping doctors determine the best course of treatment for patients. Cardiology patients at the Norfolk and Norwich University Hospital (NNUH) were the first to trial the new technology. The team hope their work [1] could revolutionise the speed at which heart failure is diagnosed, benefitting hospitals and patients world-wide.<\/p>\n<\/div><\/section>

Lead researcher Dr Pankaj Garg, from UEA\u2019s Norwich Medical School and an Honorary Consultant Cardiologist at NNUH, said: \u201cHeart failure is a dreadful condition resulting from rising pressures inside the heart. The best method to diagnose heart failure is by invasive assessment, which is not preferred as it has risks. \u201cAn ultrasound scan of the heart called echocardiography is routinely used to measure the peak velocity of blood flow through the mitral valve of the heart. However, this method can be unreliable.<\/p>\n

\u201cWe have been researching one of the most cutting-edge methods of flow assessment inside the heart called 4D flow MRI. \u201cIn 4D flow MRI, we can look at the flow in three directions over time \u2013 the fourth dimension.\u201d
\nPhD student Hosamadin Assadi, also from UEA\u2019s Norwich Medical School, said: \u201cThis new technology is revolutionising how patients with heart disease are diagnosed.<\/p>\n

\u201cHowever, it takes up to 20 minutes to carry out a 4D flow MRI and we know that patients do not like having long MRI scans. \u201cSo, we collaborated with General Electric Healthcare to investigate the reliability of a new technique that uses super-fast methods to scan the flow in the heart, called Kat-ARC. \u201cWe found that this halves the scanning time \u2013 and takes around eight minutes.<\/p>\n

\u201cWe have also shown how this non-invasive imaging technique can measure the peak velocity of blood flow in the heart accurately and precisely.\u201d The team tested the new technology with 50 patients at the Norfolk and Norwich University Hospital and at the Sheffield Teaching Hospitals NHS Foundation Trust in Sheffield.<\/p>\n

Patients with suspected heart failure were assessed using the new Kat-ARC 4D heart flow MRI. Dr Garg said: \u201cThis technology is revolutionising how we assess heart disease and our research paves the way for the super-fast 4D flow MRI scans by halving the scan time.<\/p>\n

\u201cThis will benefit hospitals and patients across the whole world,\u201d he added. NNUH Medical Director Prof Erika Denton said: \u201cNNUH is proud to have taken part in ground-breaking research which has the potential to improve the diagnosis and treatment of people with heart disease.\u201d<\/p>\n<\/div><\/section>
