From: Diffusion tensor-based fiber tracking of the male urethral sphincter complex in patients undergoing radical prostatectomy: a feasibility study

Fig. 2

Axial views obtained from DSI Studio showing the region of interest (ROI) placement on the color-coded FA maps for the proximal sphincter (A1) and distal sphincter (A2), and on the T2-weighted image for the apex (A3) and bulb (A4) to track the membranous urethra. Fiber tracking results derived from the DTI images of an arbitrarily chosen study patient are shown for the proximal sphincter (B1), distal sphincter (B2), and membranous urethra (B3), color-coded based on the direction of the fibers—red for left–right (x), green for anterior–posterior (y), and blue for superior-inferior (z) directions. MRI T2-weighted image of a patient’s mid-sagittal slice labelled with the relevant anatomy, where the orange lines define the proximo-distal extent imaged in the DTI acquisition (C1)
