Risk of Malignancy Index (RMI) Calculator

As part of clinically working up possible malignancies, the RMI score is often used to determine the likelihood that a mass/cyst seen on ultrasound warrants special consideration and/or consultation to gynecology oncology. This tool aims to simply the process. A score of 200 or more indicates a high malignancy risk.

This calculator is based off of the article Initial Evaluation and Referral Guidelines for Management of Pelvic/Ovarian Masses available through the SOGC.
