摘　　要：多层螺旋CT结合回顾性心电门控技术,可采取多相位窗的冠状动脉图像,从中筛选最佳图像并利用后期图像重建技术可模拟出冠状动脉的三维结构。此技术对冠状动脉病变的筛查与诊断、冠状动脉支架置入术及搭桥术后的评价等方面有独特的优势。因其微创、安全、分辨率高等优点,多层螺旋CT冠脉成像的临床应用前景越来越广阔。Combined retrospectively electrocardiographically(ECG)-gated image reconstruction with multislice spiral CT(MSCT)coronary reconstruction,optimal tomographic images can be screened from those multi-phase window of coronary artery(CA)images.Reconstructed by related software,3-dimensional reconstructions of CA images were performed.This method have some particular superiority in diagnosis of coronary artery disease(CAD),in evaluation of effects after intracoronary stent implantation and coronary artery bypass graft(CABG).The mini-invasion,low-risk and high-differentiation of MSCT make it have abroad clinical application in coronary angiography.
