In cancer in the head and neck region, the facial (nVII) and trigeminal (nV) nerves can be affected by microscopic or macroscopic perineural growth. For radiotherapy treatment, the affected nerves have to be included in the target volume. Therefore, high resolution MR imaging is required of nV and NVII is needed. We used T2-FFE with a binomial water selective pulse for fat suppression. High resolution T2-FFE images with an excellent quality were acquired that allow to trace the cranial nerve pathways of nV and nVII in the head and neck region.
