摘　　要：本文报告用^(99m)锝标记红细胞腹部γ-闪烁扫描检测胃肠道出血患者26例,敏感性为94％,假阴性率6％,特异性87.5％,假阳性率12.5％,定位精确性90.9％。^(99m)锝标记红细胞注入人体一周内对造血系统及肝肾功能均无明显损害。此法可持续检测24h或36h,因此对间歇性和自限性胃肠道出血有独特的诊断价值。Scintiscans using 99mTo-red blood cells were done in 26 patients with gastrointestinal hemorrhage. Of 18 patients with documented hemorrhage at the time of scanning, 17 were positive, (sensitivity, 94%; false negative, 6%). Of 8 patients not bleeding during sointigraphy, 7 had negative sointisoans (specificity, 87.5%; false positive 12.5%). Of the 17 true-positive patients, 12 were'shotwn within 1 h, 5 between 1-24h after the injection of 99mTe-RBC. Overall accuracy was 90.09% in both the detection and localization of gastrointestinal hemorrhage. There was no significant damage to the hemapoietio system, liver or kidneys. Abdominal scintigraphy with 99mTo-RBC is a safe and an effective method for detecting gastrointestinal bleeding.
