2024年12月20日 · For risk stratification, the O-RADS US system uses five categories (O-RADS 1–5), from normal (1) to high risk of malignancy (5). An O-RADS US 0 (zero) category is used for an incomplete evaluation.

2024年2月20日 · The Ovarian-Adnexal Imaging Reporting and Data System, (O-RADS), aims to ensure that there are uniform unambiguous sonographic and MRI evaluations of ovarian or other adnexal lesions, accurately assigning each lesion to a risk category of malignancy being present, and which informs the appropriate management that could be instituted.

2025年2月21日 · For ultrasound, see the Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US). O-RADS MRI serves to guide risk stratification for adnexal lesions discovered in average-risk women with no acute symptoms.

Findings are in keeping with an O-RADS US 4 lesion in the left adnexal region. O-RADS US 4 lesions carry an intermediate risk of malignancy i.e 10% less than 50%.

Here is a case illustrating the imaging criteria of the O-RADS US 3 and O-RADS MRI 3 categories.

The Ovarian-Adnexal Imaging Reporting and Data System, (O-RADS), aims to ensure that there are uniform unambiguous sonographic and MRI evaluations of ovarian or other adnexal lesions, accurately assigning each lesion to a risk category of malignancy being present, and which informs the appropria...

2025年2月21日 · Endometriomas, also known as chocolate cysts or endometriotic cysts, are a localised form of endometriosis and are usually within the ovary. They are readily diagnosed on ultrasound, with most demonstrating classical radiographic features. Epid...

2025年1月17日 · Liver Imaging Reporting and Data System Ultrasound Surveillance (LI-RADS US Surveillance) is a standardized system with recommendations for imaging technique, interpretation and reporting for surveillance of hepatocellular carcinoma (HCC) using unenhanced ultrasound in patients at high risk for developing HCC. As a surveillance tool, it is not ...

Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) and Ovarian-Adnexal Reporting and Data System Magnetic Resonance Imaging (O-RADS MRI) aim to ensure that there are uniform unambiguous sonographic and MRI evaluations of ovarian or other adnexal lesions, accurately assigning each lesion to a risk category of malignancy being ...
