Magnetic resonance defecography assessment of obstructed defecation syndrome in patients with chronic constipation in a tertiary care hospital

Figure 1 Magnetic resonance defecography T2-weighted image depicting the normal pubococcygeal line[14]. Pubococcygeal line (PCL) (yellow line) spans the inferior border of the pubic symphysis to the last visible coccygeal joint. H-line (purple) represents the length of the anterior-posterior levator hiatus. M-line (blue) measures the vertical descent of the anorectal junction below the PCL.
