目的
通过与超声（US）和数字化涎腺造影的结果进行前瞻性比较，确定磁共振（MR）涎腺造影在诊断涎腺结石中的价值。
材料和方法
对24例疑似涎腺结石的患者前瞻性地进行了MR涎腺造影，采用T2加权三维（3D）稳态相长干涉（CISS）和快速采集松弛增强（RARE）序列。诱发流涎作为对比材料。T1加权自旋回波和T2加权快速自旋回波成像也进行了。并将其结果与超声和数字化涎腺造影结果进行比较，以后者作为参考标准。
结果
在显示颌下导管系统方面，3D CISS图像明显上级RARE图像（P：<.05），其次是T2加权快速自旋回波图像（P：<.01）和T1加权自旋回波图像（P：<.001）。CISS MR涎腺造影的敏感性和特异性分别为100%和80%，RARE MR成像的敏感性和特异性分别为80%和100%。超声诊断的敏感性和特异性均为80%。
结论
诱发流涎的MR涎腺造影是无创性的，可以描绘下颌下导管系统和检测涎石，其准确性与数字涎腺造影相似，但上级于US。
PURPOSE
To determine the value of magnetic resonance (MR) sialography for the diagnosis of sialolithiasis by comparing results prospectively with those of ultrasonography (US) and digital sialography.
MATERIALS AND METHODS
MR sialography was prospectively performed with T2-weighted three-dimensional (3D) constructive interference in steady-state (CISS) and rapid acquisition with relaxation-enhancement (RARE) sequences in 24 patients suspected of having sialolithiasis. Evoked salivation was used as contrast material. T1-weighted spin-echo and T2-weighted turbo spin-echo MR imaging also were performed. The results were then compared with those of US and digital sialography, with the latter as standard of reference.
RESULTS
The 3D CISS images were significantly (P: <.05) superior to RARE images for demonstrating the submandibular ductal system, followed by T2-weighted turbo spin-echo images (P: <.01) and T1-weighted spin-echo images (P: <.001). The sensitivity and specificity were 100% and 80%, respectively, for CISS MR sialography and 80% and 100%, respectively, for RARE MR imaging. The sensitivity and specificity of US were both 80%.
CONCLUSION
MR sialography with evoked salivation is noninvasive and allows delineation of the submandibular ductal system and detection of sialoliths with accuracy that is similar to that of digital sialography and superior to that of US.
