The aim of the study was to investigate the feasibility of Diffusion-prepared MRI (D-prep MRI) to visualize the Facial nerve in head and neck cancer patients. Twenty-four patients (12 male, 60±11 year) received a D-prep MRI, where the main trunk and branches of the Facial nerve is reviewed by one neuro/head and neck radiologists. The main trunk was visible in fifteen patients and in four, six, six and one patients for the posterior auricular, zygomaticofacial, cervicofacial and temporal branches respectively. D-prep MRI is able to visualize the Facial nerve in most cases, but further improvement is required.
