The ability to obtain high-resolution images of the orbits, pharynx, skull base, larynx, and cranial nerves has greatly benefited the work-up of abnormalities in these regions, and has been an important application of MR imaging. Typically, evaluation of abnormalities in the head and neck requires careful attention to detail and a thorough understanding of the underlying anatomy.
