对 2 5例原发性高血压、血压≥ 16 0 /90mmHg ,且经过心电图、心脏远达距离摄片、超声心动图检查 ,其中至少一项符合左心室肥厚 (LVH)标准的患者 ,进行磁共振扫描成像 (MRI) ,并与上述检测结果对比 ,以估价MRI对高血压性心脏病LVH的诊断价值。结果表明 ,MRI对LVH的诊断率 (96 % )明显高于超声心动图(5 6 % )、X线 (40 % )和心电图 (2 8% )对LVH的诊断率 (P均 <0 .0 1)。且MRI可测定收缩及舒张期室壁厚度 ,可对LVH准确分型 ,可对比心脏大小、心室容量及心肌重量。MRI对LVH是一种极好的诊断方法
25 patients with essential hypertension, blood pressure ≥ 16 0 / 90mmHg, and after electrocardiogram, telephoto distance radiography, echocardiography, at least one of them in line with left ventricular hypertrophy (LVH) standard patients, magnetic Resonance scanning imaging (MRI), and compared with the above test results to evaluate the diagnostic value of MRI in patients with hypertensive heart disease LVH. The results showed that the diagnostic rate of LVH by MRI (96%) was significantly higher than that of echocardiography (56%), X-ray (40%) and electrocardiogram (28%) 1). And MRI can determine the thickness of systolic and diastolic wall thickness, LVH can accurately type, can be compared to the heart size, ventricular volume and myocardial weight. MRI is an excellent diagnostic for LVH
