腮腺磁共振造影在舍格伦综合征诊断中的价值

目的：探讨腮腺磁共振造影在舍格伦综合征（SS）诊断中的价值。方法：应用磁共振涎腺成像及磁共振造影（MRS）诊断腮腺表现为主的舍格伦综合征，在选择合理诊断标准的基础上，结合免疫学指标、病理学检查进行诊断。并与腮腺造影结果进行比较。结果：32例最终诊断为SS的25例患者中，23例MRS诊断出现典型的表现，即导管和腺泡不规则的扩张，并能排除腮腺占位性病变。敏感度：92％：特异度：71．4％；准确度：87．5％。伴有自身抗体出现的占68．％：唇腺活检符合SS表现的占72％。18例SS患者MRS与腮腺造影均有阳性表现，15例结果基本相同，占83.3％。结论：MRS能客观地反映舍格伦综合征患者受累腺体的病变情况和程度，是SS诊断和与腮腺肿瘤性疾病鉴别诊断的重要方法之一。

The value of MRS in diagnosis of Sj(o)gren's syndrome in parotid gland

PURPOSE: The purpose of this study is to evaluate the value of MR sialography in diagnosis of Sjoigren's syndrome in parotid gland. METHODS: MRI and MRS were used to diagnose Sjoigren's symdrome and differentiate with other disease combined with clinical, serologic and histopathologic result. Meanwhile, the result of MRS was compared with sialograph. RESULTS: 25 cases were ultimately diagnosed as Sjoigren's syndrome among 32 cases by clinical, serologic, histopathologic and sialography or MRS method. 23 cases were presented typical image in MRS, and sensitivity was 92%; specificity 71.4% and accuracy 87.5%. Other different manifestations were found in 25 cases, such as: autoantibody 68%, focui lymphocytic infiltration 72%. 18 cases have the positive results between MRS and sialography and 15 cases (83.3%) have the same manifestations by degree classification. CONCLUSION: The Sjoigren's syndrome can be confirmed by clinical, serologic, histopathologic, and MRS or sialography. MRS is a reliable method to diagnosis and differentiated diagnose Sjoigren's syndrome with other disease.
