Fig. 2From: The additive value of diffusion tensor imaging in the determination of perianal fistula activityHorseshoe-shaped intersphincteric fistula with positive inflammation activity. A Axial STIR image revealed intersphincteric fistula of abnormal high SI. B, C DWI & ADC map revealed high SI of fistula on b1000 images and low SI on ADC map with ADC value ~ 0.71 × 10−3 mm2/s. D axial fractional anisotropy (FA) map showed a value of 0.539Back to article page
