O-RADS MRI: A Guide to the Lexicon, Risk Score and Technique

Learn how to incorporate O-RADS™ MRI in the evaluation of patients with adnexal lesions in clinical practice through the use of lexicon terms, imaging techniques and risk stratification system. 

Viewers will become more familiar with O-RADS MRI and develop an approach to assess lesions in a stepwise algorithmic manner.

By incorporating O-RADS into clinical practice, clinicians can improve risk stratification of adnexal lesions and ensure appropriate patient management and outcomes.

Learning Objectives

  1. Describe how to accurately characterize both fluid and solid components on MRI using T1-weighted with and without contrast, T2-weighted and diffusion-weighted imaging sequences. 
  2. Identify technical requirements and the risk score categories in the O-RADS MRI risk stratification system. 
  3. Develop an algorithmic approach to analyzing adnexal lesions on MRI based on their imaging appearance.
