For example, the overall specificity for malignancy of the ADNEX MR system falls below 90% if used without dynamic contrast enhancement [71,87]. Sahin et al [19] proposed a noncontrast MRI score based on ADNEX and O-RADS models using morphologic assessment and DWI with an 84.9% sensitivity, 95.9% specificity, and 94% accuracy with the caveat of a population with a lower malignancy rate (15.1%) than the original ADNEX and O- RADS models population (18.8% and 18.4%). Noncontrast MRI may be used in adnexal mass characterization when the use of IV contrast is precluded. Clinically Suspected Adnexal Mass Variant 5: Adult patient assigned female at birth. Adnexal mass, indeterminate on initial pelvic US, no acute symptoms. Premenopausal. Follow-up imaging. CT Pelvis With IV Contrast CT pelvis with IV contrast is usually not useful for follow-up of an indeterminate adnexal mass. Because the role of US and MRI is well established, there is little reason presently to obtain a CT for follow-up of an indeterminate lesion. CT Pelvis Without and With IV Contrast CT pelvis without and with IV contrast is usually not useful for follow-up of an indeterminate adnexal mass. Because the role of US and MRI is well established, there is little reason presently to obtain a CT for follow-up of an indeterminate lesion. CT Pelvis Without IV Contrast CT pelvis without IV contrast is usually not useful for follow-up of an indeterminate adnexal mass. Because the role of US and MRI is well established, there is little reason presently to obtain a CT for follow-up of an indeterminate lesion. FDG-PET/CT Skull Base to Mid-Thigh There is no role for the use of FDG-PET/CT in the follow-up of indeterminate adnexal masses in premenopausal patients. MRI Pelvis Without and With IV Contrast An indeterminate mass can be followed by contrast-enhanced MRI. This is helpful if the mass cannot be optimally visualized by US or if the mass shows suspicious change of appearance during US surveillance.
