目的：比较磁共振(MR)涎腺造影术和常规涎腺造影术对干燥综合征唾液腺疾病的诊断准确性。材料和方法：对35例疑似干燥综合征患者进行MR涎腺造影术和常规涎腺造影术检查。采用1.5T系统进行梯度和自旋回波腮腺造影。结果：在31例(%)患者中，MR涎腺造影术与常规涎腺造影术确定的涎腺疾病分期准确相关。然而，在两名患者中，MR腮腺造影的分期较高：他们患有I期疾病，但被确定为II期疾病。在另外两名患者中，MR腮腺造影的分期较低：一名II期疾病患者和一名III期疾病患者分别被确定为II期疾病。常规唾液管造影术阶段与MR唾液管造影术阶段之间的相关性可用下列公式来估计：常规唾液管造影术阶段=0.021+0.982 x(MR唾液管造影术阶段)。结论：MR涎腺造影对干燥综合征涎腺病变的诊断具有较高的准确性。
PURPOSE: To compare the diagnostic accuracy of magnetic resonance (MR) sialography with that of conventional sialography in the assessment of salivary gland disease in Sjogren syndrome.MATERIALS AND METHODS: Thirty-five patients (32 women, three men; age range, 18-69 years) suspected of having Sjogren syndrome were examined with MR sialography and conventional sialography. Gradient and spin-echo MR sialography was performed with a 1.5-T system. MR sialographic findings were compared with conventional sialographic findings.RESULTS: In 31 (89%) patients, the stage of salivary gland disease determined with MR sialography accurately correlated with that determined with conventional sialography. However, the stage at MR sialography was higher in two patients:They had stage I disease but were determined to have stage II disease. In two other patients, the stage at MR sialography was lower: A patient with stage II disease and a patient with stage III disease were determined to have stage land stage II disease, respectively. The correlation between the stage at conventional sialography and that at MR sialography (P < .001) can be estimated with the following equation: conventional sialographic stage = 0.021 + 0.982 x (MR sialographic stage). Both the sensitivity and the specificity of MR sialography in the diagnosis of Sjogren syndrome were 100%.CONCLUSION: MR sialography is highly accurate iii the evaluation of salivary gland disease in Sjogren syndrome.
