We prospectively compared ultrasound (US) and MRI in patients with common fibular neuropathy. Methods Forty adult patients with clinical suspicion of common fibular neuropathy and 40 healthy controls underwent both US and MRI. US and MRI datasets were randomized for prospective reading. Results The overall sensitivity of US and MRI for diagnosing fibular neuropathy was 90% (95% confidence interval [CI], 79.7%‐97.3%) and 87.5% (95% CI, 71.55%‐93.1%), respectively. The overall specificity of US and MRI was 92% (95% CI, 77.45%‐96.1%) and 85% (95% CI, 73.3%‐94.4%), respectively. The overall sensitivity and specificity of US combined with MRI were 94% (95% CI, 0.80%‐0.99%) and 84% (95% CI, 0.70%‐0.91%), respectively. Overall intra‐ and inter‐observer agreements among 3 readers were 0.76% (95% CI, 0.62%‐0.85%) and 0.74% (95% CI, 0.65%‐0.81%). Conclusions US diagnostic accuracy for common fibular neuropathy was slightly higher than that of MRI. Muscle Nerve 55 : 849–857, 2017
