The Ovarian/Adnexal Reporting and Data System for Ultrasound: From Standardized Terminology to Optimal Risk Assessment and Management

Catherine H. H. Phillips et al.

Summary: The American College of Radiology (ACR) Ovarian-Adnexal Reporting and Data System (O-RADS) provides a framework for characterizing ovarian and adnexal pathology, improving reporting and patient management. Multiple validation studies have demonstrated the excellent diagnostic accuracy of O-RADS in detecting ovarian cancer, with O-RADS 4 being the optimal cut-off. Inter-read agreement is high regardless of radiologists' training level or practice experience. O-RADS shows comparable agreement to other systems like GIRADS, ADNEX, and IOTA. Further research will focus on refining lexicon terminology and risk stratification based on validation studies.

External Validation of the Ovarian-Adnexal Reporting and Data System (O-RADS) Lexicon and the International Ovarian Tumor Analysis 2-Step Strategy to Stratify Ovarian Tumors Into O-RADS Risk Groups

Stefan Timmerman et al.

Summary: Correct diagnosis of ovarian cancer is important for better prognosis. The O-RADS lexicon and the IOTA 2-step strategy can be used to stratify patients into risk groups. However, the observed malignancy rate in O-RADS 2 was not clearly below 1%.

O-RADS MRI After Initial Ultrasound for Adnexal Lesions: AJR Expert Panel Narrative Review

Elizabeth A. Sadowski et al.

Summary: The O-RADS ultrasound and MRI risk stratification systems were developed to aid radiologists in assessing adnexal lesions. Both modalities can accurately characterize benign lesions and provide additional information for further management. MRI plays a crucial role in determining the risk of invasive cancer and guiding personalized treatment options.

Benign descriptors and ADNEX in two-step strategy to estimate risk of malignancy in ovarian tumors: retrospective validation in IOTA5 multicenter cohort

C. Landolfo et al.

Summary: This study validated the use of modified benign simple descriptors (BDs) to exclude malignancy in most women with adnexal masses, and proposed a two-step strategy using the ADNEX model to estimate the risk of malignancy. The modified BDs were applicable to 37% of tumors, 99.3% of which were benign. The two-step strategy showed an AUC of 0.94.

Systematic Review and Meta-Analysis of O-RADS Ultrasound and O-RADS MRI for Risk Assessment of Ovarian and Adnexal Lesions

Qing Zhang et al.

Summary: A meta-analysis was conducted to evaluate the diagnostic performance of O-RADS ultrasound (US) and O-RADS MRI for risk stratification of ovarian and adnexal lesions. The results showed that both O-RADS US and O-RADS MRI have high sensitivity for the diagnosis of ovarian or adnexal malignancy. Understanding the diagnostic performance of O-RADS US and O-RADS MRI will be useful in clinical practice.

Predictive accuracy and reproducibility of the O-RADS US scoring system among sonologists with different training levels

Manli Wu et al.

Summary: The study aimed to investigate the predictive performance and reproducibility of the Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound system in evaluating adnexal masses among sonologists with different levels of expertise. The results showed that experienced sonologists had higher predictive accuracies and better reproducibility with O-RADS. The system also demonstrated high sensitivity and negative predictive value for each sonologist. Training is necessary for inexperienced sonologists before implementing the O-RADS classification system in clinical practice.

Shan Zhou et al.

Summary: This study evaluated the learning curve and challenging points of the Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound risk stratification system. Results showed that after training, junior doctors at different levels can reach a coincident O-RADS ultrasound risk stratification, with difficulties primarily related to subjective judgments of classic benign lesions, the color flow score, and solid-appearing masses. Experience is needed to improve the applicability of the system.

Summary: Endometriosis affects 6-10% of women of reproductive age, with about 2-4% developing in menopause. Malignant transformation in postmenopausal endometriosis poses a clinical challenge, with certain recurrent clinical conditions like previous endometriosis and estrogen-only HRT for a relatively long time showing a decrease over time. Further exploration and study are needed in this area.
