Deep learning gives major boost to tumor segmentation in prostate MRI
May 25, 2022 -- German researchers have used a convolutional neural network (CNN) to automatically segment prostate tumors in multiparametric MRI data. The CNN can produce trustworthy clinical results, even if it is trained with manually segmented data, they reported at the annual meeting of the International Society for Magnetic Resonance in Medicine.

Support grows for database of wrist fractures to enhance AI research
May 24, 2022 -- Efforts to develop artificial intelligence (AI) algorithms to help diagnose pediatric wrist fractures need to improve, say Austrian radiologists. They have developed a large annotated public dataset of x-ray images and encouraged its use in an article published on 20 May in Scientific Data. Read More

Contrast agent pooling on CT suggests imminent cardiac arrest
May 23, 2022 -- Researchers suggest that contrast agent pooling on CT -- known as the CAP sign -- are in danger of imminent cardiac arrest. The CAP sign could be addressed as an imaging feature of circulatory failure and used to predict the likelihood of cardiac arrest, they say. Read More

PET/CT reveals heart artery inflammation in COVID-19 patients
May 23, 2022 -- PET/CT imaging shows that inflammation of the aorta is increased in the early postinfection stage of COVID-19 in patients with severe disease, according to a study from Greece. Read More

MRI's 'forgotten' contrast agent makes dramatic reappearance
May 20, 2022 -- After decades of dormancy, deuterium is surging in research use as a contrast agent for MRI. Researchers discussed deuterium's potential in a presentation at the recent International Society for Magnetic Resonance in Medicine annual congress in London. Read More

Does AI pose a serious threat to radiographers' jobs?
May 19, 2022 -- Global artificial intelligence (AI) luminary Dr. Daniel Sodickson, PhD, has sought to allay fears that a "Wild West" of disruptive innovations and increased automation in the coming years could decimate the jobs of radiographers. Read More

11.7T MR spectroscopy quantifies brain glucose metabolism
May 18, 2022 -- French researchers have developed a new MR spectroscopy approach to study brain glucose metabolism, a process significantly involved in Alzheimer's disease. They presented their work at the annual meeting of the International Society for Magnetic Resonance in Medicine. Read More

Reflections on 2 years of COVID: What we got wrong
May 17, 2022 -- The COVID-19 pandemic is by no means over, and it may never truly disappear, but there have been many curious changes over the last two years, writes Dr. Paul McCoubrie in a new column. He gives a personal view on COVID's impact on radiology since 2020. Read More

Debate intensifies over precise clinical role of ultralow-field MRI
May 17, 2022 -- New portable ultralow-field MRI scanners promise to radically improve medical imaging access for patients with neurological disorders and other conditions, but which clinical indications and unmet needs will be filled with these systems? The global MRI community is striving to reach a consensus in this area. Read More
