摘要目的根据冠状动脉MR血管成像的不同信号强度(SI)模式,比较经皮冠状动脉介入(PCI)治疗慢性完全性冠状动脉闭塞(CTO)的成功率。材料与方法本研究已通过伦理审查认证,所有病人均已提交知情同意书。本研究共纳入93例病人,包括95处CTO病变,所有纳入的病人在进行PCI之前均已接受1.5 T MR稳态自由进动序列冠状动脉血
Abstract Objective To compare the success rates of percutaneous coronary intervention (PCI) in treating patients with chronic total coronary artery occlusion (CTO) according to the different signal intensity (SI) patterns of coronary MR angiography. Materials and Methods The study has been ethically reviewed and accredited and all patients have submitted informed consent. A total of 93 patients, including 95 CTO lesions, were enrolled in this study. All patients enrolled had a 1.5 T MR steady-state free precession sequence coronary artery before PCI
