Diagnostic Imaging's Weekly Scan: September 27 — October 3

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.

For patients with small cell lung cancer (SCLC), there was a 40 percent improvement in cognitive failure-free survival (CFFS) with brain MRI alone in comparison to the combination of brain MRI and prophylactic cranial irradiation (PCI), according to research presented at the ASTRO conference.

The Food and Drug Administration (FDA) issued a fast track designation for a pre-biopsy combination of 68Ga PSMA PET and prostate MRI that has demonstrated the capability to facilitate a nearly 50 percent reduction in unnecessary prostate biopsies. The BiPASS program, which combines ⁶⁸Ga PSMA PET imaging with prostate MRI prior to the use of prostate biopsy, is slated to be evaluated in an impending phase 3 trial.

In the first of a three-part Reading Room podcast episode, Wendie Berg, MD, PhD, FACR, FSBI, Manisha Bahl, MD, and Amy Patel, MD share insights on the utility of AI in breast imaging with respect to potential advantages, current concerns and future directions.

In a recent interview with Diagnostic Imaging, Joseph Cavallo, MD, MBA, offered insights on post-deployment monitoring with AI, the potential for improved workflow efficiency and the ongoing challenge of balancing essential clinical skills and AI literacy in the training of radiology residents and fellows.

A new meta-analysis comparing the use of magnetic resonance imaging (MRI), computed tomography (CT) and endoscopic ultrasound (EUS) in patients with pancreatic ductal adenocarcinoma (PDAC) demonstrates their unique strengths and complementary value. While MRI offered a 29 percent higher sensitivity than CT for differentiating liver metastases, researchers found that CT provided 12 percent higher sensitivity than MRI for assessing vascular invasion.
