Diagnostic Imaging's Weekly Scan: September 14 — September 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.

In light of emerging research suggesting an increased incidence of breast cancer among women under the age of 40, Drs. Jean Seely, MD, Zeeshan Shah, MD and Amy Patel, MD, discussed what they’re seeing in practice and emphasized increased vigilance to facilitate early detection.

In a new retrospective study published earlier this week in the New England Journal of Medicine, researchers examined the impact of radiation exposure from medical imaging in a cohort of over 3.7 million children. They estimated that radiation exposure from imaging may be associated with 10.1 percent of hematologic cancers in this patient population.

In a recent interview with Diagnostic Imaging, Drs. Noa Antonissen and Colin Jacobs discussed new research suggesting that a CT-based deep learning model may facilitate a nearly 40 percent reduction in false positives with indeterminate lung nodules on CT.

Multiple nuclear medicine societies, including the Society of Nuclear Medicine and Molecular Imaging, unveiled guidelines this week for PET myocardial perfusion imaging (MPI). Check out our takeaways from the new recommendations on appropriate protocols and keys for interpretation of PET MPI.

In a new breast ultrasound study focusing on BI-RADS category 4 and 5 mass presentations, researchers noted that the presence of echogenic rind had an 81 to 85 percent specificity for malignancy.
