Description
Basma A Elged and co-authors check a 2026 imaging shortcut for ovarian and adnexal masses: scoring them with O-RADS MRI but skipping the dynamic contrast sequence. Their retrospective study covered 148 patients with 191 masses scanned with non-dynamic contrast MRI plus diffusion imaging. Two radiologists independently assigned categories and measured diffusion values, with surgical pathology as the referee.
Agreement between readers was excellent, at a kappa of 0.901 in the study. Diffusion cutoffs separated benign from malignant masses sharply, with areas under the curve of 1.000 for solid parts and 0.952 for cystic parts at the chosen thresholds. Simple fluid, low diffusion signal in the cyst, and high cyst diffusion values independently predicted malignancy among higher-score lesions. The authors back the simplified protocol as reliable.
