摘要 目的应用超声及超声实时应变弹性成像技术对比鼻咽癌患者放疗后与对照组的腮腺形态大小及内部变化,为放疗后预测涎腺损伤提供依据。方法对鼻咽癌放疗组用加速器治疗常规面颌联合野,颈部行电子线放疗,记录两组腮腺长径、横径大小,超声实时应变弹性成像检查,对比两组腮腺的长径、横径、血流阻力指数、血流搏动指数以及弹性评分的差异。应用弹性Q-analysis分析系统分析腮腺的弹性应变率比值。结果鼻咽癌放疗组腮腺的长径和横径均小于对照组,血流阻力指数、血流搏动指数、弹性评分及弹性应变率比值均大于对照组,差异均有统计学意义(均P<0.05)。结论超声实时应变弹性成像可有效评价鼻咽癌患者放疗后腮腺损伤,可作为鼻咽癌患者放疗后涎腺损伤的有效检查手段。
