In this chapter we discuss MRN which can show current nerve pathology. RF sequences and clinical applications are discussed. Examples of nerve compressions are those affecting the sciatic nerve (e.g. piriformis syndrome), the brachial plexus nerves (e.g. thoracic outlet syndrome), the pudendal nerve, or almost any nerve in the body. The brain and spinal cord neural tracts can be followed using DTI (tractography). MRN can easily been done on 1.5- and 3T but not satisfactorily on a lower field strength which can be stressful for claustrophobic patients. MRN has been used for > than fifteen years but still several insurance companies do not reimburse the cost of it; on other sites it is a standard insurance item and commonly reimbursed. The anatomy of the cranial nerves and its origins are described in this chapter.
