摘　　要：目的探讨3D FIESTA MR涎腺造影对于涎腺梗阻性疾病的诊断价值。方法11例涎腺梗阻性患者,进行MR涎腺造影检查,并对MR数据进行后处理,重建3D图像及仿真内窥镜图像。将MR的重建图像结果与诊断内镜进行对比。结果MR涎腺造影诊断正确率为72.7%,涎腺仿真内镜与术中内镜视野具有高度的匹配性。结论MR涎腺造影能够显示涎管,MR仿真内镜可以作为术前检查的有效方法,提供手术的形态学及病理学信息。Objective To investigate the value of 3D FIESTA sequence in magnetic resonance sialography （MRS） in the diagnosis of obstructive salivary diseases. Methods Eleven patients with obstructive salivary diseases underwent MRS, and three-dimensional （3D） reconstruction and virtual endoscopic images of the salivary gland ducts were obtained after MRS data post-processing for comparison with those of sialoendoscopy. Result The diagnostic accuracy of MRS was 72.7% for obstructive salivary diseases. The virtual endoscopy provided a visual field highly consistent with that by sialoendoscopy. Conclusion MRS is capable of visualizing the tracts of salivary glands. MR virtual endoscopy can provide sufficient morphological and pathological data for preoperative assessment of salivary operations with sialoendoscopy.
