MR Neurography – Diagnostic Criteria to Determine Lesions of Peripheral Nerves

Clinical examination and electrodiagnostic testing comprise the traditional methods of diagnostic investigation in peripheral nerve disease. These are excellent tools to assess function of peripheral nerves but can be limited in localizing visualization of peripheral nerves at the fascicular level – the fascicle being the first order subunit of a peripheral nerve. The major limitation of clinical and electrophysiological examination is precisely the strength of MRN: the exact localization of nerve lesions. Lesion localization and spatial lesion patterns in the peripha lesion. Recent developments in MR scanner and coil technology and the refinement of pulse sequences for increasing structural resolution have allowed imaging of fine details in healthy and diseased peripheral nerve [1, 2]. MR Neurography (MRN) at high magnetic field strength of 3 Tesla allows for the
