Shrav Sridhar, MD discusses a retrospective study in which automated volumetric segmentation-assisted hepatic parenchymal attenuation measurement was performed on contrast-enhanced and unenhanced abdominal CT scans of a cohort of healthy adults to investigate the possibility of stratifying liver fat content on contrast-enhanced CT.
Increasing Specificity of Recommendations for Renal Incidentalomas [critique of article by Corwin et al.]
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-institutional study in AJR suggests that this cutoff should be raised to at least 30 Hounsfield units. In this episode, Matthew Petterson, MD discusses the new evidence.
