高锝酸盐(~(99m)TcO_4~-)腹部显像在Meckel's憩室诊断中的应用

目的 评价放射性核素显像在美克耳憩室诊断中的价值。方法 对１９例消化道出血，疑为美克耳憩室的患儿进行了高锝酸盐（＾９９ｍＴｃＯ４＾－）腹部显像。结果 阴性显像６例，其中５例经手术、内腔镜检查排除美克耳憩室（真阴性），１例经手术病检证实为美克耳憩室（假阴性）。阳性显像１３例，其中１２例经手术和病检证实为美克耳憩室伴异位胃粘膜（真阳性），１例为空肠粘膜下血管畸形（假阳性）。高锝酸盐腹部显像对美克耳憩室

The Application of 99mTcO4-Image to Diagnose Meckel's Diverticulum

Objedive The purpose of this study is to assess the role of radionuclide scintigraphy inthe diagnosis of Meckel's diverticulum (MD). Methods99mTcO4-imaging was performed on 19 hospitalized children with a history of gastrointestinal hemorrhge and abdominal pain. Results Among the 6 casesof negative imaging, MD was ruled out in 5 cases by operation and endoscopy(true negative), and confirmed by surgery and histology in one (false negative). Thirteen cases had active imaging. Of them, 12were proved to be MD and ectopic gastric mucosa(true opitive), and one was verfied as jejunal submucosavedar malformation. (false positive). The sensitivity, specificity and accuracy of radionuclide imagingwere found to be 92. 3 %, 83. 3 % and 89. 5 % respectively. Conclusions Pertechnetate abdominal scintigraphy is simple and easy. It should be the first choice of imaging diagnosis of MD.
