SummaryAimAs only a limited number of studies have used diffusion-weighted imaging (DWI) and conventional magnetic resonance imaging (MRI) in patients with ulnar neuropathy at the elbow (UNE), the present study aimed to investigate the diagnostic value of the non-invasive DWI technique in patients with UNE.MethodsA total of 26 elbows in 19 healthy controls (age range: 22–56 years) with no symptoms and 24 elbows in 21 symptomatic patients (age range: 21–46 years) with cubital tunnel syndrome underwent DWI. The electrophysiological and clinical criteria for the diagnosis of UNE were examined.ResultsNo pathological signal from the ulnar nerve was detected in the healthy controls, whereas there was an increase in signals on DWI in all patients with UNE. On T2-weighted (T2 W) imaging, there was increased signal intensity in 20 elbows, while low signal intensity was observed in the remaining four. A positive correlation was found between disease duration and presence of hyperintensity (P = 0.044, r = 0.42) on T2 W images.ConclusionDWI can be used together with electrophysiological methods for the diagnosis of UNE. Furthermore, DWI might be preferred in some cases, as it is non-invasive compared with the electrophysiological method for UNE diagnosis.
