| 目的 对比分析血管内超声(IVUS)与MR黑血序列冠状动脉管壁成像评价左冠状动脉斑块负荷。 方法 对拟诊为冠心病(CAD)的患者15例,于7天内分别进行IVUS和MR检查。在两种技术所获图像相对应的层面上分别测量血管横截面积、管腔横截面积计算斑块负荷,并行配对t检验、直线相关分析和Bland-Altman分析。 结果 IVUS和MRI评价血管横截面积、管腔横截面积和斑块负荷具有显著相关性,r值分别为0.59、0.68和0.59(P<0.001)。与IVUS比较,MR检查测得的血管横截面积和管腔横截面积较小,斑块负荷计算值较大,差异有统计学意义(P<0.05)。Bland-Altman分析显示IVUS和MR测量冠状动脉斑块负荷均具有较好的重复性。 结论 IVUS和MRI技术均可准确评价冠状动脉病变程度。 |

| Objective To compare intravascular ultrasound (IVUS) and magnetic resonance imaging (MRI) in evaluation on left coronary artery plaque burden. Methods Fifteen patients with suspected coronary artery disease (CAD) underwent IVUS and MRI within 7 days. The vessel cross-sectional area (CSA), luminal CSA and plaque burden were measured in corresponding slices using IVUS and MRI. The data were analyzed with paired-samples t test, simple correlation analysis and Bland-Altman analysis. Results CSA, luminal CSA and plaque burden obtained with IVUS correlated with those obtained using MRI (r=0.59, 0.68, 0.59, respectively; P<0.001). However, CSA and luminal CSA measured by MRI were less than those by IVUS (P<0.05), and the plaque burden measured by MRI was larger than that by IVUS (P<0.001). Bland-Altman analysis showed consistent trend in value of coronary artery plaque by repeated measurement using IVUS or MRI. Conclusion IVUS and MRI can well evaluate coronary plaque. |
