Levator ani muscle(LAM) dysfunction may cause pelvic organ prolapse(POP). DTI and fiber tracking was used to display the general morphology and microstructure changes of LAM in POP patients. We compared the FA, ADC values of pelvic floor muscles and fiber bundles shape between normal and prolapse group in this study. The results showed that the FA values of LAM muscle in prolapse group were lower than that of control and ADC values were opposite. DTI can realize the assessment of the status of LAM in patients with POP and guide the choice of operation methods.
