Central Necrosis and Peritumoral Edema: Histopathologic Characteristics in HER2+ Breast Cancer
Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30280
Robert Hill, MD discusses an article in which the authors evaluate associations between peritumoral and intratumoral high T2 signal intensity with histopathologic characteristics. -
Limited Diagnostic Performance of Adrenal-Protocol CT for Heterogeneous Nodules
Full article: https://ajronline.org/doi/10.2214/AJR.23.30769
Adrenal-protocol CT is commonly performed as part of the diagnostic workup of adrenal nodules, in order to distinguish adrenal adenomas from tumors. 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. -
A Critical Look at PI-RADS Upgrading Rules
Full article: https://www.ajronline.org/doi/10.2214/ajr.23.30611
Farzan Sherbaf, MD discusses a study on the need for ongoing research to refine PI-RADS criteria and emphasizes the crucial role of radiologists in contributing to this evolution through continuous follow-up of relevant clinical data. -
Free-Breathing Cine Cardiac MRI Sequence Performs as Well as Standard Breath-Hold Sequence
Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30272
Peter Gunderman, MD discusses a recent AJR study that finds that a free-breathing accelerated cine sequence with deep learning reconstruction is just as accurate as standard breath-hold SSFP sequences in estimating left ventricular measurements. 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. -
Comparative Analysis of Procedural Outcomes When Using High-Frequency Jet Ventilation Versus Spontaneous Respiration for Lung Tumor Cryoablation
Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30557
Rebecca Le, MD discusses a new article challenging the fear of using general anesthesia during percutaneous thoracic procedures, comparing high-frequency jet ventilation (HFJV) with spontaneous respiration (SR) when treating lung tumors with percutaneous ablation. -
GPT-4 Able to Precisely Identify Incidental Findings in Radiology Reports
Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30651
Hong Linda Li, MD discusses a research letter highlighting the potential use of GPT-4 into radiology reports to flag the presence of three incidental findings that may require further management.
Customer Reviews
I love AJR
AJR honestly kinda saved my life. The very song I ever heard was ‘Weak’ and I feel in love instantly. They’re songs have so much meaning to me and I relate to almost everyone of their songs. I can’t wait for they’re very new album “TMM”. Thank you, you three for saving some poor souls life. I love you guys and I can’t wait to listen to your podcast! 💙❤️💚
I like AJR
When I first heard about AJR having a Podcast I do not believe it then I saw it and I love it. I’ve listen to every single one of their songs for absolutely no reason and that’s why I love them. (This is dumb. Why did I make this?)
I LOVE THESE GUYS!!!
I LOVE AJR I ALMOST HAVE EVERY SINGLE SONG
