摘要
目的 探讨三维超声表面成像对鉴别颈动脉粥样硬化斑块的应用价值.方法 收集2009年7月至2013年6月期间在我院就诊,怀疑存在颈动脉硬化斑块病变的患者325例,先进行二维超声扫查,再行三维超声表面成像,对比两种方法的检出率,以及在评价斑块性质方面的价值.结果 二维超声诊断出现斑块人数261例,斑块发生率80.31％,三维超声表面成像诊断出斑块人数283例,发生率87.08％,两者差异无统计学意义（P＞0.05）;二维超声检出斑块总数658节,三维超声表面成像检出斑块786节,两者差异有统计学意义（P＜0.05）;两种检查方法对不同性质的斑块的检出率,经配对卡方检验,差异有统计学意义（P＜0.05）;三维超声表面成像对软斑的检出率（29.01％）略高于二维超声（22.34％）.结论 三维超声表面成像拥有强大的图像后处理方法,实现了病灶的三维观察,使图像更清晰、更直观,诊断信息更为丰富.
Objective To explore the value of three-dimensional ultrasound surface imaging in the diagnosis of carotid atherosclerotic plaques. Methods 325 patients that might have carotid atherosclerotic were collected from our hospital from July, 2009 to June, 2013. Firstly, they were scanned by two-dimensional ultrasound, then three-dimensional ultrasound surface imaging. The results of the two methods were compared. Results 658 plaques were found in 261 patients by two-dimensional ultrasound, while 786 plaques in 283 patients by three-dimensional ultrasound, with a statistical difference（P 〈 0.05）. Three-dimensional ultrasound was more sensitive in detecting soft plaques than two-dimensional ultrasound （29.01% vs. 22.34%, P 〈 0.05）. Conclusions Three-dimensional ultrasound surface imaging has good image post-processing and a three-dimensional view of the nidus, so it has clearer image and provide more diagnosis information.
