MRI诊断腰背部浅筋膜炎的临床应用价值

Value of MRI in diagnosis of lumbosacral superficial fasciitis

目的:探讨腰背部浅筋膜炎的MRI影像学特征。方法:选取有腰腿痛病史,临床拟诊为腰背部筋膜炎的患者89例,男53例,女36例。使用3.0T及0.35T磁共振机,采用自旋回波T1加权像(SET1WI)、快速自旋回波T2加权像(FSET2WI)及短时反转恢复序列(STIR)或频率选择反转恢复衰减序列(SPAIR)行腰部扫描。结果:89例患者腰背部浅筋膜层中均可见到条、片状长T1、长T2信号影,STIR和SPAIR呈明显高信号影,边界较清楚。结论:MR诊断腰背部浅筋膜炎敏感性及特异性高,可避免误诊和漏诊。

Objective： To assess the MR characteristics of lumbosacral superficial fasciitis. Methods： Eighty-nine cases of patients （53 males and 36 females） with clinical diagnosis of lumbosacral superficial fasciitis because of low back pain or（and） leg pain were included in this study. MR examination of low back was performed on a 3.0T or a 0.35T MR scanner for all the patients. The scanning sequences included spin echo T1WI（SE T1WI）, fast spin echo T2WI（FSE T2WI）, short time inversion recovery（STIR） or spectral attenuated inversion recovery（SPAIR）. Result： Lesions of long T1 and long T2 signal intensity which were high signal intensity on STIR and SPAIR with clear border were seen in the lumbosaeral superficial fascia of all the 89 cases. Conclusion： MRI has high sensitivity and specificity in diagnosis of lumbosaeral superficial fasciitis and may help in avoiding misdiagnosis and missed diagnosis.
