Wenhui Zhou, MD, PhD reviews a recent AJR article examining the performance and interreader agreement of clear cell likelihood score (ccLS) for noninvasive, imaging assessment of renal mass. This validation study bolsters the value of multiparametric MRI to predict pathologic diagnosis of incidentally detected renal cell carcinoma.

Gregory Lee, MD and Jean Jeudy, MD discuss the accuracy of visual scoring of coronary artery calcium on chest CT, regardless of contrast. By more accurately reporting these scores, large groups of patients may greater benefit from preventative treatment of coronary disease.

Xiaochen Denise Liu, PGY 5, discusses an article in which the preliminary findings suggest the need for modification of the current consensus for CKD risk factor prior to outpatient administration of iodinated contrast.

Rosalind Gerson, PGY3, discusses a study that compared the diagnostic performance of stress myocardial perfusion imaging (MPI) and CT Angiography with AI-Quantitative CT (CTA + AI-QCT) in detecting obstructive coronary artery stenosis, with invasive angiography serving as the reference standard. CTA + AI-QCT demonstrated better diagnostic performance than MPI. Modelling of diagnostic algorithms showed that incorporating CTA+AI-QCT reduced both costs and rates of invasive testing.

The key step in the creation of a transjugular intrahepatic portosystemic shunt (TIPS) is the needle puncture from a hepatic vein to a portal vein. This can be challenging in patients with portal vein thrombosis, where the portal vein is poorly visualized. Liwei Jiang, MD, discusses a feasibility study that employs a previously described technique of placing a guidewire into the right hepatic artery to serve as a landmark for the target portal vein.

Radiation safety is important, particularly in pediatric imaging. Viet Le, MD discusses an article that demonstrates how a deep learning-based algorithm reduces radiation dose in pediatric CTs compared to current techniques without loss of image quality.

Ground-level fall is a common injury in older patients and a frequent cause of ED visits. These low impact falls may lead to intracranial hemorrhage, which is a particular concern in patients on antithrombotic therapy. In this episode, Sara Tedla MD, discusses a recently published study in AJR, which evaluates traumatic intracranial hemorrhage on CT after minor head trauma in adult patients on antithrombotic therapy.

Gregory Michael Lee, MD discusses an article on applying strategies that better identify benign intrapulmonary lymph nodes and using volumetric-based measurements result in improved specificity without loss in sensitivity, as compared to Lung-RADS version 1.1.

We are moving towards patient-centered care and thus, it is important to listen to patients’ feedback. Hyunjoong William Kim discusses an article that evaluated the role of an individual hospital’s effort to make the provider reviews from patients transparent and public on its website; specifically, it looked at if there were any score differences between the radiologists and the non-radiology physicians. Radiologists, particularly those who are involved in direct patient care, may be subjected to similar patient review and ratings mechanisms as other clinical providers and this article is a good starting point to think about the ever-changing healthcare field.

Management of nonmalignant architectural distortion on DBT remains controversial. Alexandra Millet, MD discusses study results suggesting that imaging surveillance rather than surgery can be considered for architectural distortion on DBT yielding radial scar without atypia or other concordant benign pathologies without atypia.
