Diagnostic Imaging’s Weekly Scan: April 26 — May 2

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.

On Thursday, President Donald Trump nominated breast radiologist Nicole Saphier, MD, to serve as Surgeon General.

Called a “star physician” by President Trump, Dr. Saphier is a board-certified breast radiologist and associate professor of radiology at Weill Cornell Medical College and Memorial Sloan Kettering Cancer Center. Dana H. Smetherman, MD, the CEO of the American College of Radiology, said Dr. Saphier is a “tireless advocate for women’s health.”

In recent interviews with Diagnostic Imaging, Wendie Berg, MD, PhD, Stamatia Destounis, MD, and Manisha Bahl, MD, shared their concerns about the recent breast cancer screening guidance from the American College of Physicians.

Patients who had a total tumor volume (TTV) complete response (CR) on six-week SPECT/CT imaging had a 16 percent higher survival rate at two years in comparison to those who didn’t have TTV CR, according to new prospective research published in Radiology earlier this week.

In a recent interview with Diagnostic Imaging, Matthew Hulse, a certified nuclear medicine technologist, discussed the evolution of amyloid PET imaging in managing patients with Alzheimer’s disease, the impact on PET imaging volume and the emergence of quantification platforms for monitoring treatment efficacy.

Here is a clip from the interview.

In an independent test set, a radiomic AI model demonstrated an 82 percent AUC for detecting pancreatic ductal adenocarcinoma on computed tomography (CT) scans at a median of nearly 16 months prior to clinical diagnosis, according to new research published in the journal Gut.
