In patients at high risk for hepatocellular carcinoma, progression to higher categories from LR-2 and LR-3 observations remains a concern with surveillance of these lesions. Tune into this podcast to hear the results of a recently published study in AJR that found low progression rates of LR-2 and LR-3 observations with insights and comments from our special guest, the developer and leader of LI-RADS, Claude Sirlin, MD, who is an abdominal radiologist and professor at the University of California San Diego.

Percutaneous ablation is an effective treatment for sarcoma lung metastases that improves survival with minimal damage to healthy lung. Two increasingly used ablation modalities, microwave ablation and cryoablation, have not been directly compared. Liwei Jiang, MD, discusses a new study that compares the outcomes following microwave ablation and cryoablation of sarcoma lung metastases.

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.
