Diagnostic Performance of Magnetic Resonance Imaging in Female Gynecological Pelvic Masses


The Department of Radio-diagnosis, Faculty of Medicine, Ain Shams University


Abstract Background: Magnetic resonance imaging (MRI) is an excellent noninvasive technique to evaluate and characterize the gynecological pelvic masses, due to its high spatial reso-lution, excellent tissue contrast, and multiplanar imaging capability. MRI is often used to supplement ultrasonography (USG). Aim of Study: To evaluate the accuracy of MR imaging in the detection and characterization of gynecological mass lesions and to study the spectrum of diverse nature of pelvic mass lesions, to determine the origin, tissue content and characterization of pelvic masses. Patients and Methods: This study was conducted on 30 adult female patients with clinically or ultrasonographically suspected pelvic gynecological mass, they were subjected to pelvic Ultrasound & pelvic MRI and subsequently their findings were correlated with the gold standard (histopatho-logical findings/Imaging follow-up). Results: MRI was significantly superior to ultrasound in diagnosing the pelvic masses and in the evaluation of the tumor extension, myometrium invasion, detection of lymph nodes, MRI showed Sensitivity (88.9%), Specificity (95.2%), Positive Predictive value (88.9%), Negative Predictive value (95.2%) and Accuracy (93.3%). Conclusion: MRI is an excellent tool for the assessment of disorders of the female pelvic organs, a better modality for detection, characterization of various diseases, staging patients with malignant lesions where accurate diagnosis will make an impact on their surgical and medical management planning in comparison with US.
