Fig. 2

Consecutive oblique axial T2-weighted turbo spin-echo MR images (TR/TE, 7228/100) of a 40-year-old male patient presenting with discharging perianal fistula. The manual segmentation process was done by tracing different anatomical structures in each image in different colours (a). The fistula was traced in red colour (red arrow), the internal anal sphincter in blue (blue arrow), the external anal sphincter in yellow (yellow arrow) (b), the puborectalis muscle in light green (c) and the rest of the levator plate in deep green (d)
