Reliable tractography of specific abnormal brain nerves such as the facial nerve displaced by vestibular schwannoma is necessary for estimating risk before the surgery. Single-shot diffusion EPI sequence has been used previously to reconstruct tractography of facial nerve but suffered severe distortion in the basicranial region. Here we performed high resolution anatomical and diffusion scans in patients with vestibular schwannoma, in order to track the facial nerve and provide reliable result for the surgeons to evaluate the surgical risk.
