O-RADS MRI: A Primer for Lesion Characterization

The O-RADS MRI education subcommittee has produced an enduring educational activity with aims to help learners recognize how to use the O-RADS MRI risk stratification system for adnexal lesion characterization in clinical practice. The activity has 6 different modules covering topics such as: the MRI Lexicon/Atlas, Risk Score Stratification, MRI Techniques, Diagnostic Pearls and Pitfalls, Reporting and Teaching Cases. At the end of some modules, you will be able to assess what you have learned in the provided knowledge checks and there is an opportunity to receive CME credits. In addition to the six e-learning modules, you will be able to access additional resources to O-RADS MRI, such as a dictation template and guide to using the O-RADS MRI calculator.
