【摘要】：目的探讨微血管成像技术探测颈动脉斑块内新生血管的价值,并与超声造影及动态增强磁共振灌注成像的结果进行对照分析。方法选取低回声斑块共94个,分别进行微血管成像及超声造影检查,其中18个行动态增强磁共振灌注成像检查。结果微血管成像与超声造影的结果呈现可靠的一致性,Kappa值=0.783。动态增强磁共振灌注成像与微血管成像技术检查的结果 Kappa值=0.538。结论微血管成像可探测斑块内新生血管以判断斑块的易损性,与超声造影及动态增强磁共振灌注成像的结果具有良好的一致性。
[Abstract]:Objective to study the microvascular imaging technology for the detection of carotid plaque neovascularization and the value of contrast-enhanced ultrasound and dynamic contrast-enhanced magnetic resonance perfusion imaging results were compared and analyzed. Methods a total of 94 hypoechoic plaques, respectively, microvascular imaging and ultrasonography, magnetic resonance perfusion imaging in the 18 row dynamic enhancement results microvascular imaging and contrast-enhanced ultrasound showed consistent and reliable, the Kappa value of =0.783. dynamic contrast-enhanced magnetic resonance perfusion imaging and microvascular imaging examination results Kappa =0.538. conclusion microvascular imaging can detect plaque neovascularization to determine plaque vulnerability, and contrast-enhanced ultrasound and dynamic contrast-enhanced magnetic resonance perfusion imaging the results are in good agreement.
