Ovarian-Adnexal Reporting and Data System Ultrasound – O-RADS US
What is the O-RADS Ultrasound scoring system? O-RADS US (Ovarian-Adnexal Reporting and Data System — Ultrasound) is a 5-category risk stratification system developed by the American College of Radiology (ACR) to standardize the reporting of ovarian and adnexal lesions on ultrasound. It assigns each lesion a score from 1 to 5 based on morphological features…
TIRADS US Score
The American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) is a standardized ultrasound-based risk stratification framework for thyroid nodules. It assigns points across five sonographic domains—composition, echogenicity, shape, margins, and echogenic foci—each reflecting increasing probability of malignancy. The cumulative score categorizes nodules from TR1 (benign) to TR5 (highly suspicious), with defined…
