The aim of this study was to evaluate the potential ability of readout-segmented echo-planar diffusion-weighted imaging for visualizing the pelvic splanchnic nerve, an important surgical landmark in pelvic nerve-preserving surgery. Eleven healthy male volunteers were examined using this novel technique at 3T, and successful visualization of the targeted nerve was achieved at the rate of 50%. Readout-segmented echo-planar diffusion-weighted imaging may be a promising technique to visualize the pelvic splanchnic nerve preoperatively in clinical settings.
