Article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.24415 Shrav Sridhar, MD discusses a retrospective study in which automated volumetric segmentation-assisted hepatic parenchymal attenuation measurement was performed on contrast-enhanced and unenhanced abdominal CT scans of a cohort of healthy adults to investigate the possibility of stratifying liver fat content on contrast-enhanced CT.

Recommendations from the 2017 ACR white paper on incidental renal masses suggests that small homogeneous masses measuring less than 20 Hounsfield units are probably benign, and do not require further characterization. However, new evidence from a multi-institutional study in AJR suggests that this cutoff should be raised to at least 30 Hounsfield units. In this episode, Matthew Petterson, MD discusses the new evidence.

Frederic J. Bertino, MD reviews a new AJR study in which the authors attempt to compare the clinical efficacy and technical feasibility of Splenic vein stenting and splenic artery embolization (the current standard) for the treatment of SPH.

The addition of clinical information and verified cartilage damage progression on MRI may represent a new standard in determining progression of knee osteoarthritis. Drew Gunio, MD, MS discusses a new AJR article on why 2.5 mm may now be the new number to consider when reporting medial meniscal extrusion.

Can HU reliably differentiate any benign sclerotic bone lesion (not just bone islands) from sclerotic metastases? David Robinson, MD explores the topic through the lens of a new AJR article on the subject. Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.24029

Jordan Perchik, MD discusses a new AJR study in which a team of breast imaging radiologists determine if case review and a targeted educational session can improve detection of microinvasive disease on mammography. The authors describe patterns key to upstaging DCIS and address the difficulty and limitations of detecting microinvasive disease.

In this podcast, Edgar Perez, MD reviews new AJR data on how ablation fares in the morbidly obese demographic. Additionally, this podcast may help facilitate discussions about expectations, safety, efficacy, and complications during consultations with morbidly obese patients.

Michael Nellamattathil, MD analyzes and reviews a recent AJR article on the various factors contributing to anesthesia time and exposure in pediatric patients undergoing MRI examinations and what can be done to improve these measures. Article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.23601

Jeffrey Guccione, MD highlights the keys points of a new AJR article, which retrospectively compares the imaging features on CT of coronavirus pneumonia and influenza. The importance of this research is put into the broader context of the evolving COVID-19 pandemic, including the possibility for concurrent outbreaks of SARS-CoV-2 and influenza. The strengths and weaknesses are outlined along with some future avenues for investigation. Article: https://www.ajronline.org/doi/full/10.2214/AJR.20.23304
