O-RADS MRI to classify adnexal tumors: from clinical problem to daily use.

Eighteen to 35% of adnexal masses remain non-classified following ultrasonography, leading to unnecessary surgeries and inappropriate management. This finding led to the conclusion that ultrasonography was insufficient to accurately assess adnexal masses and that a standardized MRI criteria could improve these patients' management. The aim of this work is to present the different steps from the identification of the clinical issue to the daily use of a score and its inclusion in the latest international guidelines.

Complex US adnexal masses during pregnancy: Is pelvic MR imaging accurate for characterization?

Objective: To retrospectively evaluate the accuracy of pelvic magnetic resonance (MR) imaging for the characterization of complex sonographic adnexal masses discovered in women during pregnancy.

Study Design: The study population comprised 31 pregnant women (median age: 32 years (range: 19-42); mean gestation age of 16 weeks) referred to our institution for MR imaging for characterization of an adnexal mass discovered incidentally during routine ultrasound (US) for other indications. The population comprised of 31 women, with 36 adnexal lesions (mean size: 103mm [range: 20-290]), of which 27 were benign and 9 were malignant masses.
