Feasibility of diffusion tensor imaging (DTI) with fibre tractography of the normal female pelvic floor
European Radiology, 2011Co-Authors: F. M. Zijta, M. Froeling, M. P. Paardt, M. M. E. Lakeman, S. Bipat, A. D. Montauban Van Swijndregt, G. J. Strijkers, A. J. Nederveen, J. StokerAbstract:Objectives To prospectively determine the feasibility of diffusion tensor imaging (DTI) with fibre tractography as a tool for the three-dimensional (3D) visualisation of normal pelvic floor anatomy. Methods Five young female nulliparous subjects (mean age 28 ± 3 years) underwent DTI at 3.0T. Two-dimensional diffusion-weighted axial spin-echo echo-planar (SP-EPI) pulse sequence of the pelvic floor was performed, with additional T2-TSE multiplanar sequences for anatomical reference. Fibre tractography for visualisation of predefined pelvic floor and pelvic wall Muscles was performed offline by two observers, applying a consensus method. Three eigenvalues (λ1, λ2, λ3), fractional anisotropy (FA) and mean diffusivity (MD) were calculated from the fibre trajectories. Results In all subjects fibre tractography resulted in a satisfactory anatomical representation of the pubovisceral Muscle, perineal body, anal - and urethral sphincter complex and Internal Obturator Muscle. Mean FA values ranged from 0.23 ± 0.02 to 0.30 ± 0.04, MD values from 1.30 ± 0.08 to 1.73 ± 0.12 × 10^−³ mm²/s. Muscular structures in the superficial layer of the pelvic floor could not be satisfactorily identified. Conclusions This study demonstrates the feasibility of visualising the complex three-dimensional pelvic floor architecture using 3T-DTI with fibre tractography. DTI of the deep female pelvic floor may provide new insights into pelvic floor disorders.
