Abstract

Background Gynecologic masses are the most common subject of gynecologic imaging. The usefulness of MRI is high in the characterization of adnexal masses. The ADNEX MR classification framework was launched to stratify sonographically identified adnexal masses in to five groups based on their probability of malignancy: grade 1 (no lesion), grade 2 (benign), grade 3 (probably benign), grade 4 (indeterminate), and grade 5 (probably malignant). Aim to determine the accuracy of the ADNEX MR scoring system in classification of adnexal masses at Mansoura University Hospitals (MUH). Methods A total of 48 female patients with 52 adnexal masses on ultrasound were included in this prospective study. Each patient had an MRI with conventional and functional sequences . The images were reviewed independently by two radiologists who graded the images on a scale of 1 to 5 in the ADNEX MR system. Results The malignancy rates for scores 2, 3, 4, and 5 were 0%, 0%, 23.5%, and 76.4%, respectively, for reader 1, and 0%, 0%, 29.4%, and 70.6% for reader 2. The AUC values for differentiating benign from malignant masses were 0.997 and 0.992, respectively. Using a cutoff value of >3, sensitivity, specificity, and accuracy were 98.2%, 97.1%, and 98.1% for reader 1, and 97.8%, 94.3%, and 96.2% for reader 2. Borderline tumors were more likely to be misclassified. Interobserver agreement was high (κ = 0.820, p = 0.001). Conclusion The system shows high accuracy for benign and malignant tumors, while its performance is lower for borderline tumors . Overall, the ADNEX MR scoring system reliably categorizes adnexal masses .
