Additive Role of ADC Value to ORADS in Adnexal Lesions

Summary

Evaluation of the impact of adding mean apparent diffusion coefficient (ADC mean) measurements to the Ovarian-Adnexal Imaging Reporting and Data System MRI (O-RADS MRI) scoring for adnexal lesion characterization using a combined O-RADS MRI/ADC mean reading approach.
