Diagnostic Imaging's Weekly Scan: December 14 — December 20

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.

First up is new research published in European Radiology earlier this week. For patients with primary lung cancer, a nomogram incorporating PET, CT and clinical findings offered an 87.7 percent AUC for predicting lymph node metastasis and over a 19 percent higher sensitivity than a PET-based model for predicting small lymph node ( > 1 cm) metastasis.

In a recent interview at the RSNA conference, neuroradiologist Emanuel Kanal, M.D., discussed key findings from a committee of the American Board of Magnetic Resonance Safety with respect to MRI technologist responsibilities and how the advent of remote MRI scanning and related protocols may lead to increased MRI safety.

In another interview from the RSNA conference, Sriyesh Krishnan, M.D., discussed pertinent principles in assessing AI models, ongoing monitoring of the adjunctive value and an unyielding focus on patient care.

The Food and Drug Administration (FDA) granted 510(k) clearance for a multi-direction diffusion-weighted imaging (DWI) sequence that may bolster image quality in stroke detection with the portable brain magnetic resonance imaging (MRI) Swoop system.

Irregular CT margin and an SUVmax > 6.25 were associated with greater than threefold and sixfold higher risks, respectively, for malignancy among patients with thyroid incidentalomas detected on PET/CT, according to new research published in European Radiology.
