This study was done to determine whether the sublingual gland ducts could be visualized and/or their function assessed by MR sialography and dynamic MR sialography and to elucidate the clinical significance of the visualization and/or evaluation of the function of sublingual gland ducts by clinical application of these techniques. In 20 adult volunteers, 19 elderly volunteers, and 7 patients with sublingual gland disease, morphological and functional evaluations were done by MR sialography and dynamic MR sialography. Next, four parameters, including the time-dependent changes (change ratio) in the maximum area of the detectable sublingual gland ducts in dynamic MR sialographic images and data were analyzed. Sublingual gland ducts could be accurately visualized in 16 adult volunteers, 12 elderly volunteers, and 5 patients. No significant differences in the four parameters in detectable duct areas of sublingual glands were found among the three groups. In one patient with a ranula, the lesion could be correctly diagnosed as a ranula by MR sialography because the mass was clearly derived from sublingual gland ducts. This is the first report of successful visualization of sublingual gland ducts. In addition, the present study suggests that MR sialography can be more useful in the diagnosis of patients with lesions of sublingual gland ducts.
本研究旨在确定通过磁共振涎腺造影术和动态磁共振涎腺造影术能否观察舌下腺导管及其功能，并通过这些技术的临床应用阐明舌下腺导管可视化和/或功能评估的临床意义。对20名成年志愿者、19名老年志愿者和7名舌下腺疾病患者进行了磁共振涎腺造影术和动态磁共振涎腺造影术的形态学和功能评估。接下来，分析了四个参数，包括动态磁共振涎腺造影图像中可检测到的舌下腺导管最大面积的时间依赖性变化（变化率）和数据。在16名成年志愿者、12名老年志愿者和5名患者中，舌下腺导管能够被准确观察到。三组之间舌下腺可检测导管区域的四个参数没有显著差异。在一名患有舌下囊肿的患者中，磁共振涎腺造影术能够正确诊断该病变为舌下囊肿，因为肿块明显起源于舌下腺导管。这是首次成功观察到舌下腺导管的报告。此外，本研究表明磁共振涎腺造影术在舌下腺导管病变患者的诊断中可能更有用。
