The American College of Radiology (ACR) Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound (US) risk scoring system has been studied in a selected population women referred for suspected or known adnexal lesions. This higher frequency malignant neoplasms than presenting to radiology departments pelvic ultrasonography variety indications, potentially impacting the diagnostic performance system.To evaluate neoplasm O-RADS US multi-institutional, nonselected cohort.This multi-institutional cohort study included United States who presented routine between 2011 2014, with pathology confirmation imaging follow up 2 years clinical up.Analysis 1014 lesions using stratification system.Frequency ovarian cancer system.This 913 mean (SD) age patients was 42.4 (13.9 years), 674 (73.8%) were premenopausal. overall 8.4% (85 lesions). 0.5% (3 657 lesions; <1% expected); 3, 4.5% (5 112 <10% 4, 11.6% (18 155; 10%-50% 5, 65.6% (59 90 >50% expected). 4 optimum cutoff diagnosing sensitivity 90.6% (95% CI, 82.3%-95.9%), specificity 81.9% 79.3%-84.3%), positive predictive value 31.4% 25.7%-37.7%) negative 99.0% 98.0%-99.6%).In this patient population, performed within expected range as published by ACR committee. at lower end range, partially because prevalence population. However, high maintained, when lesion can be classified an 2, is low, which reassuring both clinician patient.
