Abstract：
:MRM is a useful imaging technique that can be incorporated into routine spine MR imaging protocols without a significant increase in imaging time or patient discomfort. When combined with high quality, sequential (no inter-slice gap), axial images of the spine, the authors have found that it decreases the surgeon's need for conventional contrast enhanced myelography by showing the etiology of compression and degree of compressive effect, particularly in cases of degenerative spine disease. In select cases where greater bone detail is desired, an unenhanced CT is often sufficient. MRPNI also is a useful imaging technique that is primarily used in the evaluation of patients with radicular symptoms not explained by spine MR imaging findings. Selective MRPNI is performed based on clinical and electrodiagnostic results to evaluate extra-spinal causes of peripheral neuropathy. It is easily performed using phase array coils and is primarily used to detect traumatic axonal disruption and compressive neuropathy.
