| ［摘要］ 目的 对比腮腺导管磁共振水成像（MRS）、CT造影与X线造影在诊断干燥综合征(SS)中的作用和价值。方法 收集2011-01～2014-01共301例临床疑诊为SS患者的影像学检查资料，其中行磁共振水成像有65例，行CT造影有130例，行X线造影有106例。将磁共振、CT结果与X线腮腺导管造影结果进行对比研究，评价磁共振腮腺导管水成像诊断干燥综合症的应用价值。结果 三种检查方法的敏感度、特异度、Youden指数分别为腮腺导管MRS 95%、80%、0.75，CT造影87.5%、80%、0.675，X线造影72%、90%、0.62。腮腺导管MRS、CT造影及X线造影的ROC曲线下面积分别为0.875、0.837、0.815。结论 SS腮腺导管MRS准确性高于传统X线造影，且为无创性检查，具有较高的临床应用价值。 |

| ［Abstract］ Objective To compare the effect and value between magnetic resonance sialography(MRS),CT siaglography and X-ray sialography in the diagnosis of Sjögren′s syndrome.Methods Three hundreds and one suspected Sjögren′s syndrome,of them 65 cases took MRS,130 cases took CT sialography and 106 took X-ray sialography. 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 Sjögren′s syndrome is higher than the conventional X-ray sialography, and it is noninvasive and has high clinical value. |
