Morphometric Characterization of Levator Ani Subdivisions in Healthy Controls and Patients: An MRI Study Using 3D PICS.

ABSTRACT:

Introduction and hypothesis

To date, levator ani muscle (LAM) morphometry has been classified descriptively and semi-quantitatively. New MRI techniques enabling detailed visualization with the 3D pelvic inclination correction system (3D PICS) could offer a one-stop-shop diagnostic modality for quantitative assessment of LAM subdivisions. The aim of this controlled MRI study was to assess morphometric LAM subdivision characteristics in two distinct groups of premenopausal women, namely nulliparous asymptomatic controls and symptomatic patients (Pelvic Organ Prolapse Quantification [POP-Q] ≥ II).

Methods

Magnetic resonance imaging scans of the 22 women in each group were analyzed applying the 3D PICS coordinate system. A second reading of MRI was used to calculate interrater r
