Three-Dimensional Modeling of the Pelvic Floor Support Systems of Subjects with and without Pelvic Organ Prolapse

Figure 1

Axis magnetic resonance imaging (MRI) of a subject without ((a), (c)) and a patient with ((b), (d)) pelvic organ prolapse (POP). Top panel shows regions of the pelvis (magenta) and the levator ani muscle (orange). Middle panel shows outlines of the structures. Bottom panel shows a three-dimensional (3D) model on MRI. Note that the levator ani muscle of the control subject attaches to the pubic bones on both sides, whereas that of the POP patient has defects on the right side. Ur: urethra; Va: vagina; R: rectum; OI: obturator internus.
