Abstract:
Objective To quantitatively assess the neovascularization within human carotid atheroclerltic soft plaque in patients with cerebral infarction using real-time contrast-enhanced uhrasonography. Methods One hundred and forty-two patients with carotid athemselerotic soft plaque were divided into two groups: cerebral infarction group (n = 44)and control group (n = 98).Real-time contrast-enhanced ultrasonography was examined. Acoustics quantitative analysis was made by auto-tracking contrast quantification (ACQ)technology. Results The enhanced intensity (EI)in cerebral infarction group was significandy higher than that in control group[(14.58±4.19)dB vs (11.26±3.77)dB, P< 0.01]. The difference of arrival time (DAT)and the difference of time to peak (DTrP)in cerebral infarction group was significantly shorter than those in control group [(2.21±0.42)s vs (2.46±0.51)s,(2.13 + 0.37)s vs (2.43±0.48)s, P all < 0.01]. Conclusions The real-time contrast-enhanced uhrasonography can provide a new non-invasire and quantitative tool to assess the neovascularizafion within carotid atheroselerofic soft plaque. EI is re-garded as an independent risk factor correhtes strongly with cerebral infarction.
