Figure 17. Transverse T2-weighted gradient-echo (24/14; flip angle, 60°) MR image obtained with an endoanal coil in a 63-year-old woman with fecal incontinence demonstrates right anterior defect of the external anal sphincter (ES, arrows) and scar tissue (S) anteriorly on the left side. Thinning of the internal sphincter (IS) anteriorly (arrowheads) can also be seen.
