Evaluation of diagnostic value of pelvic MRI in endometriosis in comparison with surgical findings: A cross-sectional study

Background: Endometriosis is a multifocal gynecologic disorder during the fertility period in women. Magnetic resonance imaging (MRI) is an important diagnostic modality for this disease and can be used either alone or along with transvaginal ultrasonography. Objective: This study aims to compare the accuracy of pelvis MRI in pelvic deep endometriosis with laparoscopic findings in women referred to Shahid Sadoughi hospital in one year. Materials and Methods: This cross-sectional study was conducted on ۴۰ women suspicious of endometriosis who referred to Shahid Sadoughi hospital, Yazd, Iran from November ۲۰۲۰-۲۰۲۱. Based on clinical findings and history, participants were referred to the imaging center for pelvic MRI. Finally, the results of MRI and diagnostic laparoscopy were compared with pathologic findings. Results: The sensitivity and specificity of MRI for pelvic endometriosis were ۹۴.۸% and ۲۰%, respectively. Also, the positive predictive value and negative predictive value of MRI were ۹۰.۲% and ۳۳.۳%, respectively. Conclusion: Laparoscopy is still the gold standard of endometriosis diagnosis, but MRI with susceptibility-weighted imaging sequence is the best noninvasive diagnostic method.
