目的:锝99 m -标记红细胞扫描(Tc99m红细胞扫描)建议证实胃肠道(GI)出血。它是有争议的这些扫描是否能充分本地化的出血。本研究评估的有效性RBC扫描确认和本地化胃肠道出血。我们的假设是,这些扫描在本地化胃肠道出血,如果积极有效的连续相内成像。方法:Tc99m RBC扫描进行共有80名患者在四年期间本地化胃肠道出血(59岁男性,21岁女;年龄6 - 88(意思是,48年)。电影75年的80名患者被一位核医学医师重读蒙蔽原始阅读和病人的身份和历史。扫描的结果进行了比较与验证性研究。结果:共21患者积极扫描(28%)。其中,出血的网站在16个21个病人(76%)证实了血管造影(4/16),内镜(10/16),手术(10/16),或两者结合。 In 14 of the 16 confirmed studies (88 percent), RBC scan correctly localized site of bleeding by our rigid definition. In six patients (4 not confirmed, 2 erroneously localized), scans were positive only at greater than 15 hours. Ten of the 14 correctly localized studies and none of the incorrectly localized studies were positive in the continuous phase of imaging. CONCLUSION: Tc99m RBC scan is effective in localizing GI bleeding when positive within the continuous phase of imaging. In this population supplemental angiography or endoscopy for the purpose of localization would seem unnecessary.
