The Relationship Between Magnetic Resonance Imaging and Electrodiagnostic Studies in Patients with Ulnar Neuropathy at the Elbow

Objective: This study investigated the correlations between magnetic resonance imaging (MRI) and nerve conduction studies (NCS) in patients with ulnar neuropathy at elbow (UNE).Methods:In total, 46 who underwent MRI NCS a single center from 2014 to 2018 were included. Motor studies, including segmental inching tests, sensory performed. The 5-point severity score was evaluated based on signal change swelling fat-suppressed T2 weighted sequence. findings of grouped into 3 categories. Spearman rank test used evaluate electrodiagnostic parameters.Results:The locations lesions correlated 20 UNE, while other had no correlations. Six could not be categorized according location showed various findings. significant negative amplitude (r = -0.423, p 0.002) -0.456, 0.002), velocity -0.526, < 0.001) -0.548, 0.001).Conclusion Electrodiagnostic outcomes score, reflecting structural changes seen MRI. Combining make diagnosis localization more precise.
