摘要
目的:探讨CT泪道造影中对比剂及扫描体位的合理选择方法。方法:36例(49侧)溢泪患者行CT泪道造影检查,分别选用300mgI/ml泛影葡胺、40%碘化油行CT横断面、冠状面扫描,观察CT对泪道、阻塞平面及周围结构的显示效果。结果:CT泪道造影对49侧泪道中的48侧(98%)获得满意效果,均显示了泪道的全程或阻塞平面以上扩张部分,明确了泪道阻塞的部位和程度。结论:CT泪道造影应根据病情或观察目的选择适宜的对比剂和扫描体位。
Objective：To discuss the rational use of contrast media and body positioning in CT dacryocystography. Methods：Thirty-six patients （49 lacrimal ducts） underwent CT dacryocystography, with angiografin （300mg I/ml） or lipiodol （40%） by axial or coronal plane. Lacrimal ducts, location of obstruction and adjacent structure were showed by CT dacryocystography. Results：Of the 49 lacrimal ducts examined, 48 ducts （98%） were satisfactorily showed by CT dacryocystography. The full course of lacrimal duct, the dilated part proximal to obstruction were displayed. The location and degree of obstruction were identified. Conclusion： The suitable contrast media and scanning body position should be choosed in - terms of different pathogenetic condition or observation purposes in CT dacryocystography.
