摘　　要：目的:研究下颌下腺导管结石的磁共振涎管造影的影像学特点,为临床诊断下颌下腺导管结石提供可靠的诊断方法。方法:应用重T2加权快速自旋回波序列对14例下颌下腺导管结石患者进行磁共振涎管造影,得到下颌下腺导管和结石图像,并分析其特点。结果:结石影像呈黑色,导管为白色,14例均见结石到腺体方向主导管及分支导管扩张,结石到导管口方向从完全显影、不完全显影到完全不显影等几种表现。结论:磁共振涎管造影可以很直观地显示下颌下腺导管结石的大小和结石在导管中的部位。Objective：To study the imageology features of sialolith in Wharton’s duct with magnetic resonance sialography imaging and to provide a reliable method for diagnosing submandibular duct calculi.Methods：14 cases of submandibular gland duct stone were examined with magnetic resonance sialography using a heavily T2-weighted fast spin-echo sequence.The images of Wharton’s duct were obtained.The characteristics of the duct and stone was analyzed.Results：The sialolithes were displayed as black image and catheters were displayed white.On the images of 14 cases expansion of the main and branch duct was observed in the direction from stone to gland,however,completely imaging,incompletely imaging or non-imaging were observed from stone to orifice of duct.Conclusion：The size and location of submandibular gland duct sialolith can be visually displayed in the images of magnetic resonance sialography.
