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.

Alexandra Millet, MD discusses a new study shows that accuracy improves and recall rates decrease when DBT or AI-CAD are used as adjuncts to DM alone for surveillance of the ipsilateral and contralateral breasts in women with a personal history of breast cancer after BCT, indicating that these additional methods can reduce unnecessary callbacks. 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.

Should CT contrast media be warmed? 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.

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.
