Clinical electrophysiology of infantile botulism.

abstract：BACKGROUND:Diagnosing cervical radiculopathy (CR) can be difficult because of symptomatic overlap with peripheral neuropathies. In this retrospective observational study, we aimed to determine whether short-tau inversion recovery (STIR) magnetic resonance imaging (MRI) sequences are useful for detecting signs of denerv...
