Abstract:
Objective To investigates the feasibility of diffusion tensor imaging (DTI) and diffusion tensor tracking (DTT) for evaluation of the effect of childbearing history on female pelvic floor muscles. Methods Forty-six healthy females were divided into two groups: nulliparous and primiparous. MR conventional sequences and DTI were acquired. The optimized FA threshold value was obtained by regulating the FA to fiber tracking. The two groups were compared in terms of ADC, FA, VRA and T2-WT. Results (1)The DTT of FA 0.18 got the highest score in fiber tracking . ( 2 ) The ADC of nulliparous subjects and the subjects who had given birth were (1.24 ± 0.11) ×10-3 mm2/s, (1.33 ± 0.11) ×10-3 mm2/s (P = 0.017). There were no statistical differences in FA, VRA and T2-WT between the two groups (P > 0.05). Conclusions The optimized FA threshold of fiber tracking in pelvic floor muscles is 0.18. DTI and DTT may be used to evaluate the effect of childbearing history on female pelvic floor muscles.
