In patients from either MRI cohort, specified PSA density thresholds had similarly high negative predictive values for clinically significant prostate cancer.

In this episode, Sara Tedla MD, discusses a recently published study in AJR, which characterizes utilization of head and neck CTA in the ED, and frequency of non-routine results communication among patients' chief concerns.

A commercially available deep learning algorithm to detect reticular opacities in surgically confirmed interstitial lung disease was more accurate than radiologists. Gregory Lee, MD discusses a new AJR article that examines the use of a deep learning algorithm tool increased interobserver agreement for readers, as well as increased the sensitivity, specificity and accuracy of the radiologist.

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.

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.
