June 2023: Val M. Runge, MD, a note from the Editor
This issue of the journal, as always, has many outstanding articles, representing cutting edge research and technology in diagnostic imaging. Critical new developments and findings in our field are presented, all within the field of magnetic resonance. Advances important for current clinical imaging are presented in 4 articles. The utility of breath-hold fat-suppressed T2-weighted images of the liver is demonstrated, using deep learning-based reconstruction, for both TSE and HASTE. Deep learning diagnosis of rotator cuff tears is shown, with excellent diagnostic performance, and model accuracy similar to subspecialty-trained musculoskeletal radiologists. Further optimization of prostate cancer assessment is demonstrated with the addition of T1 mapping using a single-shot T1 FLASH approach. And, the feasibility of single breath-hold 3D MR elastography of the liver is shown, which offers further advantages for the evaluation of nonalcoholic fatty liver disease in obese patients, which are otherwise challenging to image and which represents a global health crisis. Two additional articles examine the issue of contrast agent dose reduction in MRI using deep learning based approaches, with various pros and cons.
