O-RADS MRI SCORE: An Essential First-Step Tool for the Characterization of Adnexal Masses

Area of Science:

• Radiology
• Gynecological Imaging
• Oncology

Background:

• The Ovarian-Adnexal Reporting and Data System on Magnetic Resonance Imaging (O-RADS MRI) is established for characterizing pelvic gynecological masses.
• O-RADS MRI offers added value over O-RADS Ultrasound (US) by reclassifying suspicious lesions as benign.
• Identifying solid tissue in adnexal masses is critical for determining the need for gadolinium contrast.

Purpose of the Study:

• To evaluate the O-RADS MRI score's effectiveness in characterizing adnexal masses.
• To highlight the step-by-step application of the O-RADS MRI score.
• To assess the score's potential for improving patient management in suspected ovarian cancer.

Main Methods:

• The O-RADS MRI score is applied through a systematic, multivariate analysis.
• Key steps include identifying adnexal masses, assessing peritoneal carcinomatosis, and evaluating fatty content.
• The analysis further scrutinizes wall and internal enhancement, differentiating solid tissue and malignancy.

Main Results:

• The O-RADS MRI score demonstrates high value in distinguishing benign from malignant adnexal masses.
• The score exhibits high reproducibility among radiologists.
• It aids in identifying the presence and characteristics of solid tissue within masses.

Conclusions:

• The O-RADS MRI score is a valuable tool for characterizing adnexal masses.
• Its reproducibility supports timely referral to expert centers for ovarian cancer treatment.
• Radiologists integrate O-RADS MRI with clinical and biological data for precise diagnosis and personalized treatment.
