Comparative Diagnostic Accuracy of Ultrasonography and Magnetic Resonance Imaging in Characterizing Uterine Adnexal Masses: A Prospective Study with Histopathological Correlation
Abstract: Background: Adnexal masses pose diagnostic challenges due to their varied etiology and potential for malignancy. Ultrasonography (USG) and magnetic resonance imaging (MRI) are widely used, but their comparative accuracy remains debated. Objective: To evaluate the sensitivity, specificity, and overall accuracy of USG and MRI in differentiating benign from malignant adnexal masses using histopathology (HPE) as the gold standard. Methods: A prospective study of 60 patients with adnexal masses (>5 cm) at Rama Medical College (2022?2024). All underwent trans - abdominal USG, contrast - enhanced MRI (1.5T GE), and HPE. Statistical analysis included ROC curves, PPV/NPV, and SPSS v25. Results: MRI demonstrated superior sensitivity (91.7% vs.58.3%) and NPV (97.1% vs.86.8%) compared to USG, with both modalities showing 100% specificity and PPV. MRI?s AUC (0.958) surpassed USG (0.792). Benign serous cyst adenoma (33.3%) and mucinous cystadenocarcinoma (16.7%) were common findings. Conclusion: MRI outperforms USG in characterizing complex adnexal masses, particularly for malignancy detection. It should be prioritized when USG results are inconclusive.
