急性心肌梗死(AMI)的早期确诊通常是困难的,快速和特异定位于急性坏死区域的显象剂可提供重要的诊断资料。~(99m)Tc标记葡糖二酸(GLA)显象可否提供这些资料,作者显象了一组存在AMI症状的患者。 方法 28例(男22例,女6例;平均年龄61.7岁,中位年龄65岁)因症状和体征高度提示为AMI而进监护室的且临床状况稳定的患者列入研究。所有患者都存在对硝酸酯无反应典型的胸痛时间延长,并伴有ECG上持续性的ST段改变。静脉内弹丸注射~(99m)Tc-GLA900～1110兆贝克勒尔,且在约3小
Early diagnosis of acute myocardial infarction (AMI) is often difficult, and imaging agents that rapidly and specifically target areas of acute necrosis provide important diagnostic information. Can ~ (99m) Tc-labeled glucarate (GLA) imaging provide these data, the authors visualized a group of patients with AMI symptoms. Methods Twenty-eight patients (22 males and 6 females; mean age 61.7 years, median age 65 years) were included in the study because of the high level of symptoms and signs suggestive of AMI in intensive care units and clinically stable patients. All patients had prolonged chest pain that was unresponsive to nitrates, with persistent ST segment changes on the ECG. Intravenous bolus injection of ~ (99m) Tc-GLA 900-1110 trillion becquerels, and in about 3 small
