Clear cell Likelihood Score (ccLS) is a non-invasive method to grade the likelihood of a small renal lesion being a clear cell renal cell carcinoma based on the MRI appearance. Hyunjoong William Kim, MD discusses a new AJR article in which the authors demonstrate a relationship between the ccLS and the rate of growth, as higher clear cell Likelihood Score is associated with faster growth rate of the renal lesion.

How many CT-guided lung biopsies should one perform before being considered competent? Knowing metrics for performance and how to measure performance may help set guidelines for training and clinical practice. Liwei Jiang, MD details a new study in which the authors seek to define the learning curve of CT-guided lung biopsies, looking at diagnostic accuracy and complication rates.

Lara Gabrielle L Lim discusses a new AJR study that focuses on CT changes of the pancreas before the diagnosis of pancreatic ductal adenocarcinoma. This involves six focal pancreatic abnormalities that when detected will aid in early disease detection, early disease management, and improved patient outcomes.

Jeffrey Guccione, MD discusses an article that examines the use of iohexol in a water-soluble contrast challenge for predicting non-operative management of small bowel obstruction. Technical success rates are also examined, and the real-world practicality discussed. Strengths and limitations are addressed as well, including the use of iohexol over gastrografin.

In this podcast, Tyler Richards, MD discusses an observational retrospective study that looks at risk factors for patients with non-small cell lung cancer, which they found to be advanced clinical stage at diagnosis (stage III or IV) and EGFR mutation in patients with adenocarcinoma histology. They recommend that patients in these risk groups receive a surveillance brain MRI at 12 months.

David Ballard, MD discusses an AJR article in which the authors provide a practical practice consideration for optimizing prostate MR image quality. To reduce susceptibility from rectal gas, the authors had MR technologist place 18-French rectal tubes in patients undergoing prostate MR and compared them to patients without rectal tube placement.
