Suspected peroneal tendinopathy, tears, and subluxation are often confirmed preoperatively using magnetic resonance imaging (MRI) or diagnostic ultrasound (US). No study has directly compared the accuracy of these tests for the diagnosis of peroneal tendon pathology. The purpose of this study is to directly compare MRI and US to intraoperative findings in patients who underwent surgery for suspected peroneal pathology to determine the imaging diagnostic accuracy. Operative records and diagnostic images for 21 consecutive patients who had both MRI and US prior to surgery for suspected peroneal tendinopathy, tears, or subluxation were retrospectively reviewed. The results of this review are compared with the intraoperative findings to yield the sensitivity and specificity for each imaging modality. For the diagnosis of peroneal tendon tears, US was found to have a sensitivity of 88% and specificity of 100%, compared to 100% sensitivity and specificity for MRI. In the diagnosis of peroneal tendinopathy, both US and MRI had a sensitivity and specificity of 100%. In diagnosing peroneal subluxation, US was 100% sensitive compared to 66% for MRI, and both were 100% specific. In conclusion, US was found to be more effective in diagnosing peroneal subluxation and MRI was slightly more accurate in the diagnosis of peroneal tendon tears.
疑似腓骨肌腱病、撕裂和半脱位通常在术前通过磁共振成像（MRI）或诊断性超声（US）得以确诊。尚无研究直接比较这些检查对腓骨肌腱病变诊断的准确性。本研究的目的是将MRI和US与因疑似腓骨病变而接受手术患者的术中发现进行直接比较，以确定成像诊断的准确性。对21例因疑似腓骨肌腱病、撕裂或半脱位而在手术前同时进行了MRI和US检查的连续患者的手术记录和诊断图像进行了回顾性分析。将该回顾结果与术中发现进行比较，以得出每种成像方式的敏感性和特异性。对于腓骨肌腱撕裂的诊断，发现US的敏感性为88%，特异性为100%，而MRI的敏感性和特异性均为100%。在腓骨肌腱病的诊断中，US和MRI的敏感性和特异性均为100%。在诊断腓骨半脱位时，US的敏感性为100%，而MRI为66%，两者的特异性均为100%。总之，发现US在诊断腓骨半脱位方面更有效，而MRI在诊断腓骨肌腱撕裂方面略更准确。
