| 摘 要： | 目的:评价99mTcO4-联合99mTc-RBC显像对小儿下消化道出血的诊断价值。方法:94例下消化道出血患者先进行99mTcO4-显像,阴性者再进行99mTc-RBC,显像资料均参照临床最终结果进行评价。结果:94例患者中99mTcO4-显像阳性者32例,其中29例证实为Meckel憩室,2例为小肠重复畸形,1例为空肠黏膜下血管畸形9。9mTcO4-显像阴性62例,进行99mTc-RBC显像阳性28例,经手术及胃、肠镜证实胃溃疡或肠息肉18例,空肠黏膜下血管畸形5例,其余5例及阴性病例治疗好转出院9。9mTcO4-联合99mTc-RBC显像诊断下消化道出血的灵敏度为82.1%,特异度为100%,准确度为91.9%。结论:99mTcO4-联合99mTc-RBC显像对小儿下消化道出血具有较高的定位诊断及鉴别诊断价值,且无创、简单易行、快速可靠。
