右心室供血减少在临床上较难评价,右室梗塞常易漏诊.用~(99m)Tc-MIBI SPECT心肌灌注显像检查25例正常人(平均36岁)和25例可疑冠心病人(平均59岁).病人都作了~(201)Tl显像和X线冠状动脉造影,确诊11例有右冠状动脉狭窄超过50%,其中3例有下壁心肌梗塞史.~(99m)Tc-MIBI运动和静息显像分两天进行,注射剂量555MBq,作45°右前斜位到45°左后斜位的180°SPECT显像,用电子计算机掩盖左室后,用肉眼观察右室灌注情况,并加用每隔6mm的右室横轴切面作靶心图(bull’s-eye)行客观分析.根据~(99m)Tc-MIBI右室显像,在11例右冠状动脉
Right ventricular blood supply reduction is more difficult to evaluate clinically, right ventricular infarction often misdiagnosed.Using ~ (99m) Tc-MIBI SPECT myocardial perfusion imaging examination of 25 normal subjects (mean 36 years) and 25 cases of suspected coronary heart disease patients (mean 59 years old.) All patients underwent ~ (201) Tl imaging and X-ray coronary angiography, of which 11 had a diagnosis of right coronary artery stenosis over 50%, of which 3 had a history of inferior myocardial infarction. ~ (99m) Tc- MIBI exercise and resting imaging were performed in two days with a dose of 555MBq and a 180 ° SPECT imaging of 45 ° right anterior oblique to 45 ° left oblique. After the left ventricle was masked with an electronic computer, right ventricular perfusion Objective To analyze objectively the bull’s-eye line at a distance of 6mm from the horizontal axis of the right ventricle.According to ~ (99m) Tc-MIBI right ventricular imaging, in 11 right coronary arteries
