Diagnostic Imaging's Weekly Scan: September 6 — September 12

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.

New research published in the Radiology journal earlier this week suggests that MRI-guided reconstruction may facilitate improved evaluation of amyloid brain positron emission tomography (PET) scans.

Comparing ordered-subset expectation-maximization (OSEM) reconstruction of PET imaging versus MRI-guided PET reconstructions for 120 patients, researchers noted a 12 percent higher inter-reader agreement and a 7.3 percent reduction in the false positive rate with MRI-guided PET reconstruction.

In another MRI study published in the European Journal of Radiology, researchers found that the presence of vascular hyperintensity on T2 FLAIR MRI was associated with nearly double the odds of cerebral edema in patients with acute ischemic stroke.

In a recent interview with Diagnostic Imaging, Stamatia Destounis, MD, FACR, shared her perspective on recent changes to the BI-RADS system, offering insights on contrast-enhanced mammography, reporting changes for breast MRI and ultrasound, and the importance of auditing for BI-RADS category 3 assessments.

For patients with metastatic castration-resistant prostate cancer (mCRPC), researchers found that (¹⁷⁷Lu)Lu-PSMA-I&T led to a PSA50 response in over 44 percent of patients with no reports of grade 3 or worse renal toxicity, according to a newly published multicenter study in Lancet Medical Imaging and Theranostics.

In the first of a two-part Reading Room podcast episode, Lauren Nicola, MD, Christoph Wald, MD, PhD, MBA, and Peter Shen discussed current challenges with reimbursement for AI in radiology.
