[Abstract] Objective: To assess the clinical value of dynamic MRI in diagnosis of female pelvic organ prolapse (POP).Materials and Methods: Twenty-four patients with clinically diagnosed POP underwent dynamic mid-sagittal plane pelvic MRI using single-shot fast spin-echo (SSFSE) sequence during Valsalva maneuver. MRI diagnosis and measurement were made according to HMO classification system. Of them, twenty-two patients were obtained the same MRI and clinical evaluation again after the pelvic-floor-repair surgery. Therefore, all together 46 MRI examinations were compared with the clinical evaluation statistically.Results: In 46 dynamic pelvic MRI exams, 43 MRI exams had good consistency with the clinical evaluation analyzed by Kappa test (κ=0.862). Dynamic MRI measurements had good correlation with clinical measurements in the anterior and apical compartments estimated by Spearman rank (r=0.650, r=0.520, respectively), and poor correlation with clinical measurements in the posterior compartment (r=0.290).Conclusion: Dynamic MRI examination may evaluate the pelvic organ prolapse comprehensively. It’s an effective method to assess the pelvic floor dysfunction clinically.
