摘要
目的 比较1 8F 脱氧葡萄糖 (FDG)PET显像和超声心动图 (UCG)对心肌梗死面存活心肌检查的符合情况。方法 4 0例心肌梗死患者 ,男 38例 ,女 2例 ,平均年龄 (5 6± 11)岁 ,分别行1 8F FDGPET显像及UCG检查。结果 PET显像检出坏死心肌 2 6 9个节段 ,UCG发现室壁节段运动异常2 15个节段 (检出率 79 9% )。PET显像检测心肌梗死面有无心肌存活与UCG观察室壁运动情况显著相关 (χ2 =4 9 5 3,P <0 0 0 1)。UCG室壁运动轻微异常的节段与PET显像示有部分心肌存活相关 ;而UCG室壁运动消失及矛盾运动的节段 ,与PET显像示心肌无存活相关 (χ2 =4 7 9,P <0 0 0 1)。同时PET显像在UCG室壁矛盾运动节段检出部分节段有心肌存活 (u =3 6 8,P <0 0 1)。结论 常规UCG检查观察心脏室壁运动可以初步筛选梗死累及部位的心肌存活情况 ;对UCG发现大面积室壁运动消失甚至室壁矛盾运动的患者 ,应行心肌PET显像。
Objective To investigate the concordance of 18F-FDG PET imaging and echocardiography (UCG). Methods Forty cases with myocadial infarction underwent UCG, PET and coronary angiography. Results PET showed 269 segments with necrotic myocardium, and UCG showed 215 segments (79.9%) with motion abnormalities. There was significantly correlated between PET detected viable myocardium and UCG find segmental motion(χ2=49.53 , P<0.001). Further more, there was correlation between UCG hypokinetic segments and PET myocardial viable segments. And also between UCG akinetic segments and nonviable necrotic myocardial segments (χ2=47.9 ,P <0.001). Besides, PET imaging has statistical significance (u=3.68, P<0.01) in viable myocardium of aneurysm patients with paradox wall motion. Conclusion As a screening test, first do UCG to detect the viability of the infarcted myocardial area, and then to those UCG showed large area akinetic segments or paradoxical aneurysm should undergo PET.
