Currently, two opposing trends can be observed in MRI: on the one hand 1.5T scanners are increasingly replaced by 3T scanners for standard clinical MRI applications. On the other hand scanners with lower field strengths have become commercially available in the past years. A session at ECR 2021 took a closer look at low-field (0.5T) and ultra-low-field (0.05T) MRI scanners.
Low-field MRI is the flavour of the season after several 1.5T models were launched. The major advantages of this technology are a relatively low purchasing price and operating costs and few artefacts while the image quality is comparable to a 1.5T scanner. Patient comfort is another benefit of low-field scanners. This advantage, however, tends to get short shrift despite the fact that it might…
A new study from the University of Surrey and University College London has revealed that treatment for heart attacks could be improved thanks to a novel method of evaluating heart function using contrast-based MRI scans. According to the British Heart Foundation, heart and circulatory diseases cause more than a quarter (27 per cent) of all deaths in the UK, which equates to more than 160,000…
An artificial intelligence (AI)-driven system that automatically combs through brain MRIs for abnormalities could speed care to those who need it most, according to a new study. “There are an increasing number of MRIs that are performed, not only in the hospital but also for outpatients, so there is a real need to improve radiology workflow,” said study co-lead author Romane Gauriau, PhD,…
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) want to build the world’s first prototype that tracks moving tumors with magnetic resonance imaging (MRI) in real time during proton therapy. They are combining a rotating open MRI device, designed for the LINAC-MR system from Alberta Health Services, with an actively scanned clinical-akin proton beam at OncoRay, the Dresden-based…
In an industry where every second and every click counts, workflow inefficiencies consume as much as a third of the MRI procedure time. This is a key area of focus where technology advances can radically change what is possible with an MRI exam. Given declining reimbursements, fewer skilled resources, and the system-wide burden of chronic diseases, maximizing productivity is a strategic…

Hyperpolarized MRI is a recent development and its research and application potential has yet to be fully explored. Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have now unveiled a new technique for observing metabolic processes in the body. Their singlet-contrast MRI method employs easily-produced parahydrogen to track biochemical processes in…
Magnetic resonance imaging (MRI) is widely used to identify the narrowing or blockage of blood vessels. Contrast agents improve the visibility of the structures and offer more accurate information of vascular conditions such as vascular blockage and stenosis. Commonly used gadolinium-based contrast agents must be administered in chelated forms due to the gadolinium ions' high toxicity and pose…
Whole-body magnetic resonance imaging (WB-MRI) can detect prostate cancer and inform about treatment response and disease progression earlier and better than other imaging modalities.

Improving workflow is one of the major challenges that radiology departments face. The need to be more efficient, deliver timely and effective patient care, and keep an eye on costs are all factors that seem to be ever-present in the modern imaging department. With the added demands of the coronavirus pandemic as radiology departments continue to play a critical role in the fight against…
Anyone needing a tomography gets the clearest possible images of an organ or other body structure slice by slice. But the further inside the potential problem lies, the more difficult it is to obtain high-resolution images in magnetic resonance imaging (MRI). An international team of scientists led by the University of Duisburg-Essen (UDE) has developed a high-frequency coil that allows for much…
Artificial intelligence (AI) image reconstruction dramatically reduces magnetic resonance imaging (MRI) scan time, according to new research. The first clinical study comparing AI-accelerated knee MRI scans with conventional scans shows that the AI scans are not only diagnostically interchangeable with conventional ones, but also produce higher quality images. Results of this interchangeability…
MRI is the most sensitive method to detect breast cancer. However, the current breast cancer guidelines for Europe, Germany and Austria, still only recommend it for certain indications: For early detection in high risk patients, for differentiation between scarring and recurrences after breast-conserving treatment and to detect cancers of unknown primary site. This is the theory. However, in…
Researchers at the Center for Computational Imaging and Personalized Diagnostics (CCIPD) at Case Western Reserve University have preliminarily validated an artificial intelligence (AI) tool to predict how likely the disease is to recur following surgical treatment for prostate cancer.
