Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.24245   Incidentally detected renal masses are common, and can require follow-up. 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-in...

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...

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. Article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.23847

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 use...

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...

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 action...

Compared to other guidelines, ACR TI-RADS results in a decreased number of thyroid nodules which are either followed or given a recommendation of fine needle aspiration (FNA). Find out on this podcast hosted by Amber Liles, MD, MPH, what thyroid malignancies are missed and why and how changes in size thresholds might affect ACR TI-RADS performance and outcomes. For more on this read the new  AJR a...

Although the clinical symptoms of pediatric COVID-19 pneumonia may be non-specific, some characteristic imaging findings have emerged or are currently emerging.

Vaping associated lung injury exploded into a public health crisis in 2019 in the United States and the introduction of a new term into the medical lexicon – EVALI. This episode briefly explores the history of vaping, the authors' experiences that led to this manuscript, and an update on what has changed since we first went to publication. For more on this, read Travis Henry's article in the March...

Lymph node staging in patients with invasive breast cancer and preoperative imaging of the axilla plays are essential for preoperative staging. Unlike many other areas of the body, it is the node morphology rather than size that is most revealing. Ultrasound not only allows visualization of nodes but also enables image guided biopsy. Accurate identification of axillary adenopathy can prevent unnec...

As healthcare moves into a new era of increasing information vulnerability, radiologists should understand that they may be using systems exposed to altered data or data that contains malicious elements.
