title: Magnetic resonance imaging examination of denervated muscle.
abstract: Denervated muscles due to lumbar radiculopathy, peroneal axonal neuropathy and hypoglossal neuropathy were studied with magnetic resonance imaging (MRI). Denervated muscle was clearly distinguished from normal muscle by its higher intensity signal. Comparison of the resulting signal intensity of the muscle using various imaging parameters suggests an alteration in water macromolecular binding. These preliminary findings indicate that MRI may be useful in the noninvasive in vivo diagnosis and study of the effects of denervation on muscle.
