磁共振冠状动脉成像在冠心病诊断中的应用价值

目的评价三维导航磁共振冠状动脉成像技术(MRCA)在冠心病诊断中的应用价值。方法对18例健康志愿者和15例冠心病或疑似冠心病的患者进行MRCA,并与冠脉造影结果进行对比。结果MRCA与冠脉造影结果无差异(P>0.05)。与冠脉造影相比,MRCA对于左前降支(LAD)病变的诊断符合率为94.5%,敏感度为90.8%,特异度为100.0%;对于右冠状动脉(RCA)病变的诊断符合率为82.2%,敏感度为88.7%,特异度为86.2%;对于回旋支(LUX)病变的诊断符合率为82.8%,敏感度为85.0%,特异度为76.0%。结论三维导航MR-CA在冠心病诊断中具有重要的临床应用价值。

Application Value of Magnetic Resonance Coronary Angiography in Diagnosis of Coronary Heart Disease

Objective To evaluate the application value of real-time navigator three-dimensional magnetic resonance coronary angiography in diagnosis of coronary heart disease.Methods Real-time navigator three-dimensional magnetic resonance coronary angiography (MRCA) was performed in 18 healthy volunteers and 15 patients with real or suspected coronary heart disease,and the result was compared with that of coronary angiography.Results There was no statistic difference of the diagnosis between MRCA and coronary angiography( P >0.05).Compared with angiography,the coincidence rates of the diagnostic result in MRCA were 94.5% for left anterior descending,82.2% for right coronary artery,and 82.8% for left circumflex; while the sensitivities were 90.8%,88.7%,and 85.0% respectively; and the specificities were 100.0%,86.2% and 76.0% respectively.Conclusion Real-time navigator three-dimensional magnetic resonance coronary angiography in diagnosis of coronary heart disease has a great application value.
