心脏大血疾病 MRI 诊断的初步经验

Initial Experience of MRI Diagnosis of Cardiovascular Diseases

本文分析41例作过心电图门控磁共振成像(ECG—G—MRI)的心脏大血管疾病的MRI表现,并与心血管造影、心导管检查、彩色多普勒超声显像及手术所见相比较。MRI 没有放射幅射,不需使用造影剂即可清楚刻画出心脏大血管腔、心肌和心包,随着设备和技术的进步,MRI 诊断许多获得性和先天性心赃大血管的能力增强,堪与损伤性的心脏大血管造影和心导管检查媲美。

The results of the examinationswith electrocardiographic gated mag-netic resonance imaging(ECG-G-MRI)of 41 patients with,cardiovascular di-seases were analyzed and were com-pared with the results of angiocardiography(ACG),cardiaccatheterization(CC),colour Doppler echocardiography(CDE)and surgery.ECG-G-MRI candelineate clearly the cardiac pathoana-tomy including cardiovascular lumen,myocardium and pericardium withoutionizing radiation and intravascularcontrast materials,With the progressof MRI equipment and technology, diagnostic capability of ECG-G-MRIis strengthened especially in intracar-diac and paracardiac masses,cardio-myopathy,congenital diseases and tho-racic-aortic disease,and may matchwith that of invasive ACG and CC.
