The authors retrospectively reviewed 15 magnetic resonance (MR) studies of elbows with radiographic evidence of nerve disorders. These 15 cases were selected from 55 MR studies of the elbow in patients referred for various complaints. MR images of the elbow of 10 healthy volunteers were also reviewed. Ulnar nerve disorders were seen in 11 cases. Three patients had median nerve disease, and one patient had a pathologic condition of the radial nerve. The following nerve abnormalities were detected: focal or diffuse nerve thickening, increased signal intensity on T2-weighted images, and course deviation due to either mass effect or spontaneous subluxation. Six of seven patients with nerve thickening, two of two patients with increased nerve signal intensity, and five of eight patients with nerve displacement complained of neurologic symptoms. Four of the patients underwent surgery; in each, surgical results confirmed the findings at MR. These results suggest that MR imaging has a potential role in the detection of nerve disorders at the elbow and in the guidance of treatment.
作者回顾性分析了15例肘部磁共振（MR）研究，这些研究均有神经疾病的影像学证据。这15例病例是从55例因各种主诉转诊患者的肘部MR研究中挑选出来的。还对10名健康志愿者的肘部MR图像进行了分析。11例患者存在尺神经疾病。3例患者患有正中神经疾病，1例患者存在桡神经病变。检测到以下神经异常：局灶性或弥漫性神经增粗、T2加权图像上信号强度增加以及因占位效应或自发性半脱位导致的走行偏差。7例神经增粗患者中有6例、2例神经信号强度增加患者中有2例、8例神经移位患者中有5例出现神经症状。4例患者接受了手术；每例患者的手术结果均证实了MR检查结果。这些结果表明，MR成像在检测肘部神经疾病及指导治疗方面具有潜在作用。
