Diagnostic Imaging's Weekly Scan: May 17 — May 23

Welcome to Diagnostic Imaging’s Weekly Scan, which offers an opportunity to catch up on the most well-viewed radiology content of the past week.

Delayed-only image acquisition for contrast-enhanced mammography after neoadjuvant chemotherapy offered a greater than 17 percent higher sensitivity rate than early-only image acquisition for detecting residual disease, according to a new study.

In a study of 351 women with BI-RADS 3-5 non-mass enhancement breast lesions, researchers found that multiparametric MRI offered 98.4 percent sensitivity and a 97.9 percent negative predictive value (NPV).

In the latest episode of his “Interventional Radiology in Focus” series, Mina Makary, MD, discusses current and potential pre-procedure, intra-procedure and post-procedure applications of AI for interventional radiology.

The addition of density heterogeneity on CT to a predictive model for differentiating malignant and benign sub-centimeter pulmonary nodules led to a greater than 15 percent improvement in the model’s AUC, according to a new multicenter study published in Insights into Imaging.

A retrospective comparison of AI X-ray platforms from seven different manufacturers for stand-alone lung cancer detection revealed sensitivity rates ranging between 20.8 percent to 77.8 percent.
