Denervated skeletal muscle: MR imaging. Work in progress.

摘要: PURPOSE: To evaluate the change in signal intensity of skeletal muscles after denervation and to determine clinical usefulness magnetic resonance (MR) imaging diagnosis denervation. MATERIALS AND METHODS: Denervated associated with various forms peripheral neuropathy spinal radiculopathy were studied MR 17 patients. RESULTS: On T1-weighted images, denervated was normal 14 patients high three. T2-weighted all showed on at least one image. High images observed 15 or more days onset paralysis. In two patients, returned relief CONCLUSION: is a noninvasive accurate method for use may ultimately eliminate need electromyography.
