Comparative study on magnetci reson ance sialography, CT sialogar phy and X-rya sialography inS j?gren′s syndromeal
Abstract：Objective To compare the effect and value between magnetic resonance sialography (MRS),CT siaglography and X-ray sialography in the diagnosis of Sj ?gren′s syndrome .Methods Three hundreds and one sus-pected Sj?gren′s syndrome,of them 65 cases took MRS,130 cases took CT sialography and 106took X -ray sialogra-phy.And these results were compared .Results These three methods′sensitivity, specificity and Youden index were as following:MRS:95%, 80%, 0.75 , CT sialography:87.5%, 80%, 0.675 , X-ray sialography: 72%, 90%, 0.62 respectively .The area under the ROC curve of MRS , CT sialography and X-ray sialography were 0.875 ,0.837 , 0.815 respectively.Conclusion MRS′s accuracy in the diagnosis of Sj ?gren′s syndrome is higher than the conven-tional X-ray sialography, and it is noninvasive and has high clinical value .
