A simplified approach to ovarian lesions based on the O-RADS US risk stratification and management system.

Compared to the risk-oriented approach to ovarian lesions that is presented in the Ovarian- Adnexal Reporting and Data System (O-RADS) US Risk Stratification and Management System as a guideline, a lesion-oriented flowchart is more user-friendly for radiologists. In the present article, the O-RADS guideline has been depicted in the form of a single flowchart to explain how to approach ovarian lesions in an algorithmic manner. In addition to providing a practical flowchart, this pictorial article contains some images of the related ovarian lesions.
