Diagnostic Imaging's Weekly Scan: November 16 — November 22

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.

Emerging research, recently published in European Radiology, reveals significantly higher accuracy for photon-counting detector computed tomography (PCD-CT) in detecting obstructive coronary artery disease (CAD) in contrast to energy-integrating CT (EID-CT) and may facilitate a nearly 15 percent reduction of referrals for invasive coronary angiography (ICA) procedures.

Comparing annual emergency department encounters that involved a head CT in 2007 and 2022, the authors of a new study in Neurology, noted a 51 percent increase in head CT scans and also found significant disparities in access to head CTs for Black patients, those on Medicaid and patients in rural hospital settings.

In a recent interview with Diagnostic Imaging, Christoph Lee, M.D., discussed key findings from the ASSURE study, which evaluated the use of a multi-stage AI-driven workflow for over 579,000 women who had digital breast tomosynthesis (DBT) exams.

Earlier this week, the Food and Drug Administration (FDA) granted a fast track designation for the positron emission tomography (PET) imaging agent ITM-94 in the detection of clear cell renal cell carcinoma (ccRCC). In addition to ITM-94 demonstrating favorable tolerability and a high tumor-to-background ratio for ccRCC in preliminary study findings, researchers for an ongoing phase 1/2 trial are currently evaluating the effectiveness of ITM-94 in classifying indeterminate renal masses.

New multinational research, published in Radiology, suggests that a mammography radiomic model may help predict the emergence of occult invasive breast cancer in women with confirmed ductal carcinoma in situ (DCIS).
