Sagittal T2-weighted MRD image at maximal pelvic floor contraction (squeeze). The pubococcygeal line (PCL) serves as a reference line extending from the inferior border of the pubic symphysis to the last coccygeal joint. The H line represents the anteroposterior dimension of the levator hiatus, while the M line measures the perpendicular descent of the levator plate relative to the PCL. The midpubic line (MPL) provides an additional reference for anterior-posterior alignment. Identifiable pelvic structures include the pubic symphysis (Ps), rectum (R), and bladder (B).
