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.

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
Video from ISMRM 2022: Thoralf Niendorf on MRI field strength
May 16, 2022 -- Is the future all about low-field MRI, or will high-field scanners continue to have an important role to play in clinical imaging? For answers, we caught up with Prof. Thoralf Niendorf, PhD, at the International Society for Magnetic Resonance in Medicine (ISMRM). He remains an enthusiastic supporter of ultrahigh-field MRI.
