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.

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.

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.

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.

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.

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.

In this episode, John Do, MD speaks with TIPS expert Dr. Jonas Redmond, interventional radiologist and associate professor at the University of California San Diego, to discuss the results of a recently published study in AJR that supports the utility of FIPS score in differentiating patients who are optimal candidates.
