Diagnostic Imaging's Weekly Scan: May 10 — May 16

New multicenter ultrasound research raised questions about the reliability of the Ovarian-Adnexal Reporting and Data System (O-RADS) for differentiating between malignant and benign ovarian and adnexal lesions. Researchers found that 135 out of 219 lesions originally characterized as O-RADS 4 or 5 were actually benign.

In a recent interview with Diagnostic Imaging, Leslie Lamb, MD, MSc, discussed findings from new mammography research that showed an 89.3 percent sensitivity for detecting invasive lobular carcinoma (ILC) with adjunctive AI.

In the latest episode of her “Breast Imaging in Focus” series, Manisha Bahl, MD, MPH, FSBI, discusses a new study of breast arterial calcification on mammography and practical clinical implications for breast radiologists. As Dr. Bahl points out, breast arterial calcification, which has been linked to higher risks of cardiovascular disease, was identified in 22.7 percent of women and increased with age from 8 percent in women younger than 50 to 61 percent in women older than 70.

In another recent interview with Diagnostic Imaging, Shadpour Demehri, MD, discussed new research findings suggesting a correlation between emphysema-like changes on CT and reduced bone mineral density in patients without chronic obstructive pulmonary disease (COPD).

Here is a clip from the interview.

In an Emergency Radiology study involving nearly 350 completed requests for CT scans at a pediatric hospital emergency department, researchers found that 54 percent were not appropriate according to American College of Radiology appropriateness criteria.
