TC-99m-HMPAO白细胞扫描诊断临床表现不肯定的急性阑尾炎
A99m Tc-HMPAO具备穿透血脑屏障的脂溶性、零电荷、分子量小三个基本条件 B脂溶性的 99m Tc-HMPAO在脑内的分布与脑血流成正比 C99m Tc-HMPAO主要排泄途径为肝胆道和泌尿系统,24小时排出注射量的40%左右 D99m Tc-HMPAO进入脑组织后固定分布在脑内,并且出现脑内再分布的现象 E99m Tc-HMPAO配制后主张标记后10...
临床表现不典型的急性阑尾炎有时很难确诊,辅助检查诸如钡灌肠.CT和B超扫描仍不能提高总的确诊率,作者观察锡(Tc)99m-六甲基丙烯儿茶芬胺肟(HMPAO)血白细胞扫描对这类病例的诊断价值.抽取40～50ml静脉血,离心后分次会除红细胞和血小板,提纯白细胞,与30mCi99mTc-HMPAO一起孵育15分钟,加入5ml少血小板血浆,用150g...
