摘要
目的:探讨MRI对肘管综合征的影像及临床应用价值。方法:对18例肘管综合征患者和20例健康成年人行肘部3.0T MR横轴面、冠状面及矢状面扫描,扫描序列包括SE T1WI、脂肪抑制SE T2WI和脂肪抑制SE PDWI。对比分析患者组和对照组中肘部尺神经的信号及形态特点。结果:患者组和对照组中尺神经的横截面积分别为(0.17±0.08)和(0.07±0.01)cm^2,两组间差异有统计学意义(P<0.001);两组中尺神经/肌肉信号强度比分别为2.82±1.41和1.56±0.38,两组间差异有统计学意义(P=0.002)。18例肘管综合征患者中有13例行肘管内尺神经减压术,5例行保守治疗。结论:MRI可显示肘管综合征患者肘部尺神经的变化,是一种能较好地评估肘管综合征的检查方法。
Objective:To explore the clinical application value of MRI for cubital tunnel syndrome. Methods:Eighteen patients with cubital tunnel syndrome and twenty healthy volunteers (control group) were examined by MRI in coronary, sagittal and axial position. The scan sequences were as follows:SE T1WI, SE T2 WI and fat-suppression SE PDWI. Signal in- tensity and size of ulnar nerve in patient and normal group were measured and compared statistically. Results:The area of ul- nar nerve in the patient and control group was (0.17±0.08)cm2 and (0.07 ± 0.01)cm2 , there was statistically significant difference (P〈0. 001). The relative signal intensity of ulnar nerve in patient group and control group was (2.82 ± 1.41) and (1.56 ± 0.38), there was statistically significant difference (P= 0. 002). Among the eighteen patients, thirteen were operated for ulnar nerve decompression, five underwent conservative treatment. Conclusion: MRI can show the changes of size and signal intensity of ulnar nerve in patients with ulnar neuropathy,it is an useful method in evaluating ulnar neuropa- thy at the elbow.
