Pins and Needles From Fingers to Toes: High-Resolution MRI of Peripheral Sensory Mononeuropathies.

OBJECTIVE

The purpose of this article is to review advanced MRI techniques and describe the MRI findings of pure sensory mononeuropathy with relevant clinical and anatomic correlation.

CONCLUSION

Peripheral sensory mononeuropathy can be challenging to evaluate with MRI because of the small caliber of pure sensory nerves and the lack of changes in secondary muscular denervation. Advances in MRI afford the necessary signal-intensity contrast and resolution for adequate evaluation of many of these small peripheral nerves.
