Abstract
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,thev 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. Key words: Three-dimensional ultrasound surface imaging; Carotid atherosclerotic; Plaques
