OVARIAN-ADNEXAL REPORTING AND DATA SYSTEM FOR US (O-RADS US) IN OVARIAN CANCER

Abstract

OBJECTIVE: to describe the new System called Ovarian-Adnexal Reporting and Data System for US (O-RADS US) supported by the American College of Radiology to standardize the lexicon in the description of characteristics of ovarian and adnexal masses and assign risk categories for the probability of malignancy Based on the assessment of these characteristics, management recommendations are also standardized. METHODS: Bibliographic review. For risk stratification, the O-RADS US system recommended six categories (O-RADS 0–5), incorporating the range of normal to high risk of malignancy. RESULTS: In the studies found, the results for sensitivity, specificity, PPV, NPV and kappa of the method were significant with the use of the OvarianAdnexal Reporting and Data System (O-RADS) risk stratification and management system. CONCLUSION: This system was designed to provide consistent interpretations, to decrease or eliminate ambiguity in US reports, resulting in a greater likelihood of accuracy in assigning malignancy risk to ovaries and other adnexal masses, and to provide a management recommendation for each category. of risk. O-RADS US is the only lexicon and classification system that covers all risk categories with their associated management schemes.
