肘关节疾病的MRI研究

目的探讨MRI在肘关节病变的应用价值。方法154例有肘关节疼痛、活动障碍或不适患者行肘关节MR检查，包括冠状位、矢状位及横断位成像，序列包括T1wI自旋回波（T，WISE），T2WI自旋回波压脂（T：WIFS），质子密度加权成像自旋回波压脂（PDWIFS）。俯卧位108例，仰卧位46例，使用膝关节线圈及表面线圈。结果154例患者中，关节正常表现25例，关节异常患者129例（83．8％）。其中炎性疾病38例（29．5％），包括骨性关节炎32例，风湿性关节炎5例，关节结核1例。肿瘤或肿瘤样疾病28例（21．7％），包括滑膜软骨瘤病4例，腱鞘巨细胞瘤1例，神经鞘瘤3例，腱鞘囊肿5例，滑膜囊肿15例。损伤性疾病63例（48．8％），包括韧带损伤24例，肌腱损伤28例，尺神经损伤11例。结论磁共振对肘部疾病的诊断具有很好的价值。

MR research of elbow diseases

Objective To study the diagnostic value of elbow diseases on magnetic resonance imaging （MRI）. Methods 154 paitionts with unilaleral elsow diseases patients （age range：14～63 years, with elbow discomfort, pain or elbow joint swelling） were scanned with MRI （Tl-weighted-spin-echo, Tz-weighted-spin-echo-fat-suppression, PD-weighted-spin-ech- o-fat-suppression）. Of 154, 108 were supine, 46 were prone. Results Among 154 patients, 25 patients were normal, the ratio of the abnormity was 83.8 %. 38 （29.5 %） were inflammatory diseases, including osteoarthritis （32）, rheumatoid ar- thritis （5）, joint tuberculosis （1）; 28 （21.70%） were tumors or tumor-like diseases, including synovial chondromatosis （4）, pigmented villonodular synovitis （1）, neurinoma （3）, tendon sheath cyst （5）, synovial cyst （15） ; 63（48.8%） were traumatic diseases, including ligaments tear （24）, tendons tear （28）, ulnar neuropathy （11） ; 25 patients were normal. Conclusion MRI plays an important role in the diagnosis of elbow diseases.
