MRI of Muscle Denervation in Central and Peripheral Nervous System Disorders

Neuroimaging of classic neuralgic amyotrophy

“…In some but not all cases, gadolinium enhancement helps to establish the diagnosis of neuritis. Moreover, MRI is particularly valuable for visualizing muscle denervation patterns associated with NA . However, due to the limited field of view at a given resolution, only certain segments of the peripheral nerves can be depicted in detail, which can lead to false negative results.…”

“…Moreover, MRI is particularly valuable for visualizing muscle denervation patterns associated with NA. 8,9 However, due to the limited field of view at a given resolution, only certain segments of the peripheral nerves can be depicted in detail, which can lead to false negative results. Ultrasound may be an alternative, because high-resolution probes of 15 MHZ and above offer sufficient spatial resolution to judge morphology and, therefore, pathology of nerves as small as <1 mm diameter.…”
