~(99m)Tc-焦磷酸盐(ppi)或~(111)In-抗肌球蛋白抗体(AM)显像对急性心肌梗塞可提供有价值的诊断和预后信息.本文研究急性心肌梗塞发病后几天至几周不同时期,~(99m)Tc-ppi和~(111)In-AM显像的诊断意义.方法:急性心肌梗塞24例(男22,女2;36～80岁).显像时间:8例在发病后1周内;7例在1～2周内;9例在2周后.在急性发作至显像检查之间均无胸痛复发和心肌酶升高.555～740MBq~(99m)Tc-ppi静注3h后,进行前位、LAO45°及70°和左侧位平面显像,300～500k·c/帧.接着在皮试后,将74MBq~(111)In-AM(含0.5mg AM Fab)缓慢静注,48h后显像,体位和帧计数与ppi显像相同.显像心肌放射性强度分为五级,0~+:无确切的放射性摄
~ (99m) Tc-pyrophosphate (ppi) or ~ (111) In-antimyosin antibody (AM) imaging can provide valuable diagnostic and prognostic information for acute myocardial infarction.This study investigated the pathogenesis of acute myocardial infarction The diagnostic significance of ~ (99m) Tc-ppi and ~ (111) In-AM imaging in different days, weeks and weeks.Methods: 24 cases of AMI (male 22, female 2; 36-80 years old) Like time: 8 cases within 1 week after onset; 7 cases within 1 to 2 weeks; 9 cases after 2 weeks .Acute onset to imaging examination were no chest pain recurrence and myocardial enzymes .555 ~ 740MBq ~ (99m) Tc-ppi 3h after the anterior, LAO45 ° and 70 ° and the left side of the plane imaging, 300 ~ 500k · c / frame.Then after the skin test, 74MBq ~ (111) In -AM (containing 0.5mg AM Fab) slowly intravenously, after 48h imaging, position and frame count and ppi imaging the same.Developmental myocardial radioactivity intensity is divided into five, 0 ~ +: no exact radioactive photo
