摘要
目的探讨磁共振对皮肌炎的诊断价值及临床意义。方法收集我院2012年2月～2013年6月13例接受过MRI检查的皮肌炎患者资料，且都有病理结果，评价MRI对皮肌炎的临床应用价值。结果13例皮肌炎患者在MRI均有异常表现，主要累及臀部肌群及两侧大腿外侧肌群，T2WIFS及DWI两个序列对病变的显示效果最好，敏感度最高，其中肌肉炎性水肿性改变及皮下脂肪水肿13例，肌筋膜增厚8例。结论MRI检查是一种无创、敏感的检查方法，与肌酶、肌电图及肌肉穿刺相比较，有更高的阳性率，是诊断皮肌炎累及范围及进展程度的重要检查手段。
Objective To study the value of MRI imaging and its significance in the diagnosis of dermatomyositis. Meth- ods Thirteen patients with dermatomyositis were enrolled in this experiment. All the patients were scanned with MRI up- on their thigh and had pathological results. Results All the patients had abnormal appearance in MRI. T2 WI FS and DWI sequences were the most sensitive sequences in finding the lesions of dermatomyositis, lesions involving the buttocks mus- cles on the both sides and the lateral thigh muscles. The findings included muscle edema and subcutaneous fat edema in13 patients, thickening in fascia in 8 patients. Conclusion MRI is a non-invasive, sensitive technique that is important to di- agnose dermatomyositis extent and degree of progress and MRI had a higher positive rate than the muscle enzymes, elec- tromyography and muscle biopsy.
