MRI superior in characterizing high-risk adnexal lesions

MRI has advantages over transvaginal ultrasound (TVUS) when characterizing adnexal lesions based on the Ovarian-Adnexal Imaging-Reporting-Data System (O-RADS), according to findings published October 27 in the European Journal of Radiology. A team led by Isabelle Thomassin-Naggara, MD, PhD, from the Assistance Publique–Hôpitaux de Paris in France, found that MRI is on par with TVUS when it comes to sensitivity, but it has higher specificity. “MRI should be the recommended second-line technique when a mass is discovered during TVUS and is rated O-RADS 4 and 5 over than TVUS by an ultrasound specialist,” the Thomassin-Naggara team wrote. Accurate characterization of adnexal lesions is important for deciding the best course of action for treatment. TVUS is the first-line option in this area. The researchers pointed out that while both ultrasound and MRI can assess solid lesion components, solid tissues, and components can appear echoic on TVUS. MRI is typically the go-to modality when an adnexal lesion is considered “complex” or “indeterminate” on ultrasound. The American College of Radiology’s (ACR) O-RADS scoring scale meanwhile aims to standardize the characterization of such lesions, with scores of 4 and 5 indicating intermediate and high risk of malignancy, respectively. Thomassin-Naggara and co-authors wanted to investigate the diagnostic performance of O-RADS ultrasound performed by an expert sonographer and O-RADS MRI scores to find out for which l...
