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."

Percutaneous Ablation as an Effective and Safe Option for Patients With ILD and Early-Stage NSCLC Jan 03, 2024

In this podcast, Alessandro Micelli, MD discusses an article on safety and efficacy of percutaneous ablations in patients with ILD and NSCLC are analyzed, taking into consideration the appearance and grading of adverse events and local tumor control.

Investigating the Use of Perfluorobutane for Contrast-Enhanced Ultrasound Diagnosis of Hepatocellular Carcinoma Jan 03, 2024

Show notes

Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30156

Sid Dogra, MD discusses an article in which the authors investigate various combinations of imaging acquisitions and diagnostic criteria for hepatocellular carcinoma using contrast-enhanced ultrasound with the agent perfluorobutane.

Lung Biopsy Is Riskier in Patients With Usual Interstitial Pneumonia, Or Is It? Jan 03, 2024

Show notes

Full article: https://www.ajronline.org/doi/abs/10.2214/AJR.23.29938

Peter Gunderman, MD discusses a study finding complications of lung biopsy are more common in patients with usual interstitial pneumonia (UIP), but only when the proceduralist traverses findings of UIP–a surprising discovery that raises questions about patient positioning and lung biopsy safety.

Can Photon-Counting CT Transform Infrapopliteal Vascular Imaging Jan 03, 2024

Show notes

Farzaneh Ghazi Sherbaf, MD discusses an AJR article analyzing recent research using photon-counting detector CT to better visualize and characterize infrapopliteal arteries by providing higher spatial resolution compared to conventional CT to overcome calcified plaque artifact, even with lower IV contrast media dosage.

IMG Faculty in Academic Radiology Departments Dec 20, 2023
