magnetic resonance neurography

magnetic resonance imaging technique that can detect peripheral nerve abnormalities Indications: - evaluation of foot drop [2] Procedure: - standard 1.5 Tesla MRI with special phased-array imaging surface coils - image data are acquired simultaneously from multiple coils - image data from each coil in the array are combined to form a composite image with an improved signal-to-noise ratio [2] - images can be processed to allow stacking of axial sections & slicing of data in another plane of section - helpful in mapping longitudinal extent of nerve involvement Clinical significance: - high-resolution images of peripheral nerves, as well as associated intraneural & extraneural lesions - shows fascicular organization of peripheral nerves, thus rendering nerves distinguishable from other tissue
