心脏磁共振成像延迟增强与冠脉造影在冠脉疾病中的应用比较

Application comparison of the late gadolinium enhancement-cardiovascular magnetic resonance and coronary angiography in the diagnosis of coronary artery disease

目的比较心脏磁共振延迟增强(LGE-CMR)和冠脉造影(CA)对冠状动脉疾病(CAD)的诊断价值。方法收集24例具有完整CA及LGE-CMR资料的CAD病例,比较LGE-CMR和CA诊断CAD的差异。结果 CA法诊断CAD 21例,其中6例仅见冠脉硬化,15例病人发现21段固定狭窄段。LGE-CMR诊断CAD 20例。LGE-CMR方法及CA法诊断CAD正确率比较,差异无统计学意义(χ~2=0.92,P>0.05)。结论 LGE-CMR可用于CAD的诊断,可作为CA法有益的补充。

Objective To compare the diagnostic value of late gadolinium enhancement-cardiovascular magnetic resonance( LGE-CMR)and coronary angiography(CA)for coronary artery disease(CAD). Methods The CAD patients with completed CA and LGE-CMR data were collected to analyze the difference between CA and LGE-CMR for diagnosing CAD. Results Totally 21 cases were diagnosed as CAD by CA method,coronary plaques in 6 patients,and 21 stenosis in 15 patients.20 cases were diagnosed as CAD by LGE-CMR method.The difference in diagnostic value between the two methods was not significant(χ^2=0.92,P>0.05). Conclusion LGE-CMR can be used as a useful complement to the CA method for the diagnosis of CAD.
