Synopsis

This lecture will present O-RADS MR score which was developed to predict malignancy of adnexal masses. This score is an accurate five level categories score that demonstrates a sensitivity and specificity higher than 90% and a good reproducibility (Kappa >0.8). In a multicentric european large validation cohort, only 2 borderline and no invasive cancer were quoted O-RADS MR score 2 (NPV = 98%). This score is mainly based on the analysis of solid tissue using morphological and functional criteria including T2W signal, DW signal and the analysis of time intensity curve on DCE MR sequence.
