Impact Of Deep Learning Reconstruction On Image Quality And Diagnostic Performance Of Accelerated Shoulder MRI

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.26071  Wenhui Zhou, MD, PhD reviews a recent AJR article examining the diagnostic performance of six different imaging modalities in the detection of sporadic pheochromocytoma, and the science behind several radiotracers used in the detection of pheochromocytoma. This study supports the use of 18F-FDOPA as the first-line imaging modality in the workup of suspected adrenal pheochromocytoma.

In the ipsilateral breast, addition of AI-CAD resulted in lower recall rates and higher accuracy than did the addition of DBT. This suggests that AI-CAD may help address the challenges of post-BCT surveillance mammograms.

Currently, the ACR has not provided conclusive recommendations, and data to guide decision-making has been sparse. In this episode, John Do, MD discusses a recently published study showing that prewarming iohexol 350 may not be necessary to reduce the risk of extravasation and reaction rates.

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.21.25979  Clear cell Likelihood Score (ccLS) is a non-invasive method to grade the likelihood of a small renal lesion being a clear cell renal cell carcinoma based on the MRI appearance. Hyunjoong William Kim, MD discusses a new AJR article in which the authors demonstrate a relationship between the ccLS and the rate of growth, as higher clear cell Likelihood Score is associated with faster growth rate of the renal lesion.

Knowing metrics for performance and how to measure performance may help set guidelines for training and clinical practice. Liwei Jiang, MD details a new study in which the authors seek to define the learning curve of CT-guided lung biopsies, looking at diagnostic accuracy and complication rates.
