摘　　要：目的:通过对比研究,优化磁共振涎管造影技术的方法。方法:依次采用短时反转恢复序列(STIR)、重T2WI快速自旋回波序列(重T2WIFSE)、单次激发快速自旋回波序列(SSFSE),厚层扫描,快速采集,并于口含维生素C前后分别扫描。结果:30例分析比较,STIR序列较重T2WIFSE扫描涎管的显示效果明显提高(P<0.05),SSFSE序列虽较STIR序列成像时间短,但其分辨率及信噪比较差。口含维生素C后,涎管的显示效果有一定程度的提高,但不显著(P>0.05)。结论:口含维生素C与STIR序列并用能更好的显示涎管主干及其分支,具有较高的临床实用价值。Objective:To optimize the technology of MR Sialography by contrast study. Method:STIR, T 2WI FSE, SS FSE were performed in turn before and after given two pieces of Vit C in patients' mouths. Thick slices and fast acquisition were used.Result:30 cases analyzed, compared to T 2WI FSE, the display of the parotid gland ducts were more improved(P<0.05) and the resolution was higher and signal-noise ratio was better in STIR. But the scan time was shorter in SS FSE. After given two pieces of Vit C in patients' mouths, the display of the parotid gland ducts was improved slightly, but has no significant difference (P>0.05). Conclusion:The parotid gland ducts and its peripheral ductal branches can be displayed well by using STIR and given Vit C at the same time. There is high clinic value.
