摘要
目的对比超声彩色多普勒血流显像（CDFI）与e—Flow技术在椎动脉（VA）检查中的作用。方法选择高频超声血流显示较为困难的健康体检者24例，其中男性14例，女性10例，年龄22～58岁（平均年龄44岁），对于同一个受试者分别使用彩色多普勒血流显像及e—Flow技术了解椎动脉血流的显示情况，并使用Photoshop图像软件进行有效像素分析。结果CDFI和e—Flow组血管像素占总像素的比例分别4．2‰±2．2‰、7．1‰±2．9‰，两组比较差异具有统计学意义（P〈0．05）。结论e—Flow技术对于常规检查较为困难的人群，血流显示效果优于CDFI。
Objective To compare the efficacy of color Doppler flow imaging （CDFI） with e-Flow technique in vertebral artery （VA） examination. Methods Twenty-four healthy subject （male 14, female 10, aged 22 - 58 years, mean age 44 years） whose VA was difficultly displayed in high frequency flow ultrasonography, both CDFI and e-Flow respectively for each subject were performed, compared the display patterns of VA flow and analysed their effective pixels with Photoshop software. Results The arterial pixel in CDFI and e-Flow was 4.2 ‰ ± 2.2 ‰, 7.1‰ ±2.9‰ of the total pixel respectively and significant difference was found（P 〈 0.05）. Conclusion It is demonstrated that e-Flow technique is superior to CDFI in examination of VA flow in the population difficultly detected by conventional approach.
