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.

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.

COVID 19 has been shown to affect a variety of organ systems. In this podcast, Ben Kipper, MD examines the association between stroke subtypes and COVID-19 as well as the effect that association may have on clinicians and radiologists.

On this episode, Alicia Chen, MD takes a closer look at a very timely new AJR article titled, "Lung US Findings in Coronavirus Disease-19 (COVID-19) Patients" by Yao Zhang and colleagues from Beijing Ditan Hospital and Peking University Third Hospital. Compared to CT, ultrasound is portable, less costly, and does not use radiation. These characteristics suggest ultrasound could be particularly useful tool for triage, particularly in the pre-hospital/outpatient setting, and severity stratification and monitoring, particularly of critically ill patients who may be challenging to transport and require careful ventilation management. This study demonstrates that lung ultrasound has a high sensitivity for COVID-19 pneumonia in moderate and severe disease and that sonographic findings can suggest infection length and severity. Ultrasound is a promising adjunct modality for COVID-19 management.

In this episode, Yoon-Jin Kim, MD, discusses a study evaluating factors associated with background parenchymal enhancement (BPE) on contrast-enhanced mammography. The findings are important as BPE impacts study interpretation and high BPE may be an independent breast cancer risk factor. The study findings are valuable for physicians currently interpreting this emerging breast imaging modality and those considering integrating it into their own clinical practice.

Metabolic syndrome is typically thought of as a clinical disease. In this podcast, Shrey Patel explores reevaluating the role of imaging in identifying and potentially diagnosing patients at risk for metabolic syndrome by using CT biomarkers.

Shravan Sridhar, MD, MS discusses his study in AJR that provides a retrospective review of patients with abnormal renal uptake Technicium 99m MDP bone scans in which the causes of abnormal renal uptake, imaging follow up, and interventions are assessed. The study identifies several different conditions responsible for abnormal uptake, ranging in levels of clinical significance and degree of actionability. This study underscores the importance of careful assessment of the kidneys on whole body bone scan.
