An example that features an AI-generated report that identified “scattered pulmonary granulomatous calcifications.” In the first session, three of five readers specifically reported the presence of a nodule. Following the introduction of the AI-generated report, only one reader maintained the specific mention of a nodule, whereas the other four readers adapted their reports to include the AI-suggested terminology of “granulomatous calcifications.” AP = anterior-posterior.

CEM improves breast cancer detection rate over low-energy mammography

By Amerigo Allegretto

Contrast-enhanced mammography (CEM) improves breast cancer detection over low-energy mammography in screening settings.

Images depict true-positive findings in a 51-year-old woman with a left breast focal nonmass enhancement. (A) Mediolateral oblique and (B) cranio-caudal contrast-enhanced mammographic (CEM) images show the enhancement (arrows). No correlate was identified on (C) mediolateral-oblique or (D) craniocaudal low-energy images, or whole-breast ultrasound (not shown). Contrast-enhanced breast MRI shows a suspicious enhancement on (E) sagittaland (F) axial subtraction images (arrows), correlating with the finding on CEM images. MRI-guided biopsy (not shown) showed flat epithelial atypia, withsubsequent surgery confirming ductal carcinoma in situ.
