| 摘 要： | 目的 比较3.0T磁共振全心对比增强冠状动脉成像(CE-CMRA)与传统冠状动脉造影(CAG)对可疑冠心病(CAD)检出的能力,探讨临床应用3.0T CE-CMRA的可行性。 方法 对30例可疑CAD患者在1周内先后行CAG和CE-CMRA检查。CE-CMRA检查应用心电门控、呼吸门控、反转回复序列、分段梯度回波序列,以0.3 ml/s速率注入钆贝酸二葡甲胺(0.2 ml/kg)和15 ml生理盐水,延迟60 s开始采集数据。以传统CAG为金标准,计算CE-CMRA的诊断敏感度、特异度和准确率。应用Kappa一致性检验评价两种检查方法的一致性。 结果 成功完成26例CE-CMRA检查, CE-CMRA诊断CAD患者、段落、各支血管的准确率分别为84.62%(22/26)、78.30%(285/364)、87.50%(56/64),阳性预测值分别为81.82%(9/11)、81.05%(124/153)、91.67%(22/24),阴性预测值分别为89.47%(17/19)、80.62%(208/258)、90.32%(56/62)。CE-CMRA对右冠状动脉的显示率为86.15%(112/130);左主干100%(26/26);前降支98.46%(128/130);回旋支83.33%(65/78)。26例CE-CMRA中,17例图像为Ⅳ级,8例为Ⅲ级图像,1例为Ⅱ级图像,无0级和Ⅰ级图像。 结论 3.0T CE-CMRA的图像质量符合诊断要求,可作为检出CAD的一种方法。 |

| Abstract: | Objective To compare the detective ability of 3.0T whole heart contrast enhanced coronary magnetic resonance angiography(CE-CMRA) and conventional coronary angiography(CAG) for coronary artery diseases(CAD),and to explore the clinical application feasibility of 3.0T CE-CMRA.Methods CE-CMRA and CAG were performed within one week in 30 patients with suspected CAD.Successful CE-CMRA was obtained in 26 patients,ECG-gated,respiratory gating,inversion recovery sequences and segmented gradient echo sequence techni... |
