AJR Podcasts

In this AJR Conversation, IR Section Editor Anne Covey, MD, speaks with Shamar Young, MD, about his team's recently published article on thermal ablation of thyroid nodules.

Xiao Xiao Tong discusses an AJR article that found interreader agreement assessed among ten radiologists was substantial both for the Society of Radiologists in Ultrasound risk category assignment and for the surgical consultation recommendations. In particular, the variability was less relevant in the recommendation for surgical consultation and in assigning the indeterminate risk category. ARTICLE TITLE - Society of Radiologists in Ultrasound Consensus Conference Recommendations for Incidental Gallbladder Polyp Management: Interreader Agreement Among Ten Radiologists

In this episode of the AJR Podcast Series on Wellness, Sherry Wang MBBS discusses feeling unwell. The episode addresses the state of physician burnout, depression, moral injury, and personal experiences.

He discusses the system’s impact on streamlining scans and its potential for broader application despite the complexities in pediatric radiology. The conversation includes insights from Dr. Ryan Chung's interview on the project's nuances and reflects on the initiative's success in efficiency and error reduction.

However, there has been limited evaluation of its efficacy in heterogeneous nodules. Sid Dogra, MD discusses a recent multi-institutional study evaluating different methods of ROI placement and show that adrenal-protocol CT generally has poor diagnostic performance in distinguishing adrenal adenomas and non-adenomas in heterogeneous nodules.

An accurate free-breathing cine sequence could benefit patients who have difficulty holding their breath and decrease scanning times, but there are limitations to the study that may hinder wider adoption.

It shows that pure ground-glass nodules have better surgical outcomes and may be monitored noninvasively, whereas nodules with increased density may need surgery.

With a focus on the need for pediatric-specific datasets CAD systems, the podcast analyses the study's methodology and results.

No statistically significant difference was observed between these two groups, including in subgroups of patients on active surveillance and patients with no prior prostate cancer history.

However, Schoen et al. prove otherwise by measuring CT net scan energy consumption and estimated savings on one of their scanners at Wake Forest. The authors found that a high correlation between CT dose report metrics and CT scanners’ net scan energy consumption and that net scan energy savings could be extracted from a reduction in dose report metrics without requiring a sensor. The authors also measure the impact on CT energy savings, which is greatly impacted by reducing idle state energy consumption, or the energy the CT produces from being “on.”
