Peripheral neuropathies of the foot and ankle can be challenging to diagnose clinically due to concomitant traumatic and nontraumatic or degenerative orthopedic conditions. Although clinical history, physical examination, and electrodiagnostic testing comprised of nerve conduction velocities and electromyography are used primarily for the identification and classification of peripheral nerve disorders, MR neurography (MRN) can be used to visualize the peripheral nerves as well as the skeletal muscles of the foot and ankle for primary neurogenic pathology and skeletal muscle denervation effect. Proper knowledge of the anatomy and pathophysiology of peripheral nerves is important for an MRN interpretation.
足部和踝关节的周围神经病在临床上的诊断具有挑战性，这是由于同时存在创伤性和非创伤性或退行性骨科疾病。尽管临床病史、体格检查和电诊断测试（包括神经传导速度和肌电图）主要用于识别和分类周围神经疾病，但磁共振神经成像（MRN）可用于可视化足部和踝关节的周围神经以及骨骼肌肉，以发现原发性神经病变和骨骼肌肉失神经效应。正确了解周围神经的解剖结构和病理生理学对于 MRN 解读非常重要。
