摘要
目的探讨眼睑及泪腺部病变的彩色多普勒血流成像特点。方法应用彩色多普勒超声对166例患者的眼睑及泪腺进行检查,观察正常眼睑、泪腺及病变眼睑及泪腺的形态改变,同时与眼科专用超声诊断仪的检查结果相对照。结果彩色多普勒超声较眼科专用超声诊断仪可更清晰地显示眼睑及泪腺的全貌,对眼睑及泪腺部病变内部回声的显示亦优于二维超声,且可以同时叠加血流信号,观察病变的血流情况。形态与血流的结合对泪腺部病变的诊断较单纯应用眼科专用超声诊断仪对病变性质的确定更有帮助。结论彩色多普勒超声成像是眼睑及泪腺部病变诊断的好方法。
Objective To investigate the normal and pathologic ultrasonographic characteristics of eye lid and lacrimal gland.Methods A total of 166 cases who had eye lid and lacrimal gland diseases were examined on color Doppler flow imaging(CDFI),and the results were compared with those on B-mode ultrasound in ophthalmological setting.Results CDFI was better than B-mode ultrasound in showing the eye lid and whole lacrimal gland;it was also superior to 2-dimensional ultrasound in showing the internal echoes of eye lid and lacrimal gland diseases,and at the same time it could superpose the blood flow signals for observing the blood flow in the diseases.Combination of morphology and blood flow features was a better choice for diagnosis of eyelid and lacrimal gland diseases than those simply on B-mode.Conclusions CDFI may be the optimal choice for the diagnoses of eyelid and lacrimal gland diseases.
