The aim of this study was to investigate the clinical application of DTI fiber tractography on evaluating the levator ani injury after first vaginal delivery. Thirty-five primiparous women with 6 weeks after vaginal delivery and twenty-five age-matched nulliparous women volunteers as control group were included. The primiparas women were divided into 2 subgroups by the existence of pelvic organ prolapse. DTI with fiber tractography provided satisfactory 3D representation of pubovisceralis while the study of iliococcygeus was more difficult. No significant differences of FA and ADC values were found among primiparous normal group, primiparous POP group and control group for pubovisceralis.
