Adrenal-protocol CT is commonly performed as part of the diagnostic workup of adrenal nodules, in order to distinguish adrenal adenomas from tumors. However, there has been limited evaluation of its efficacy in heterogeneous nodules. Sid Dogra, MD discusses a recent multi-institutional study evaluating different methods of ROI placement and show that adrenal-protocol CT generally has poor diagnostic performance in distinguishing adrenal adenomas and non-adenomas in heterogeneous nodules.

Farzan Sherbaf, MD discusses a study on the need for ongoing research to refine PI-RADS criteria and emphasizes the crucial role of radiologists in contributing to this evolution through continuous follow-up of relevant clinical data.

Peter Gunderman, MD discusses a recent AJR study that finds that a free-breathing accelerated cine sequence with deep learning reconstruction is just as accurate as standard breath-hold SSFP sequences in estimating left ventricular measurements. An accurate free-breathing cine sequence could benefit patients who have difficulty holding their breath and decrease scanning times, but there are limitations to the study that may hinder wider adoption.

Shruti Kumar, MD study that investigates the outcomes of patients with pure ground-glass nodules, heterogeneous ground-glass nodules, and part-solid nodules. It shows that pure ground-glass nodules have better surgical outcomes and may be monitored noninvasively, whereas nodules with increased density may need surgery.

Xiao Xiao Tong discusses a study that conducted a comparative analysis between patients who underwent multiparametric MRI and those who underwent biparametric MRI, in terms of NPV. No statistically significant difference was observed between these two groups, including in subgroups of patients on active surveillance and patients with no prior prostate cancer history.

Rebecca Le, MD discusses an article that combines the relationship between radiology and sustainability, which could sound like an unlikely combination to some. However, Schoen et al. prove otherwise by measuring CT net scan energy consumption and estimated savings on one of their scanners at Wake Forest. The authors found that a high correlation between CT dose report metrics and CT scanners’ net scan energy consumption and that net scan energy savings could be extracted from a reduction in dose report metrics without requiring a sensor. The authors also measure the impact on CT energy savings, which is greatly impacted by reducing idle state energy consumption, or the energy the CT produces from being “on.”
