摘　　要：目的:研究99mTc-高锝酸盐(99mTcO4-)异位胃黏膜显像特点与临床特征之间的相关性。方法:观察MD异位胃黏膜患者,行99mTcO4-显像与手术后病理诊断的符合率,核素扫描特征与临床特征,并用Pearson相关分析法进行分析。结果:MD异位胃黏膜患者消化道出血临床严重程度与病检中憩室合并溃疡、出血率密切相关(rp=0.68,P<0.01),与核素扫描中异位胃黏膜最大直径显像时间明显负相关(rp=-0.57,P<0.05),与核素扫描中异位胃黏膜显像的最大直径无明显相关(rp=0.32,P>0.05)。结论:99mTcO4-显像诊断MD异位胃黏膜的敏感性高、阳性预测值强。憩室黏膜溃疡、出血可能是导致MD异位胃黏膜患者发生消化道出血的重要原因。Objective： The present study was designed to evaluate the diagnostic value of ectope gastric mucosa＇s technetium99m pertechnetat （99mTcO4^-） SPECT in patients with Meckel＇s diverticulum （MD） resulted from ectope gastric mucosa, and to investigate the correlation between 99mTcO4^- SPECT for Meckel＇s diverticulum and its clinical characteristics. Methods： Retrospective study was performed in the patients who visited the 1st hospital affiliated Shanxi Medical University and the Central Hospitol of Taiyuan during Jan. 2000 to Jun. 2006. All of the patients diagnosed pathological as Meckel＇s diverticulum with ectope gastric mucosa after operation were concluded into the present study. The diagnostic coincidence between pathological findings and 99mTcO4^- imaging results was investigated. Furthermore, the characteristics of 99mTcO4^- imaging, and the relationship between the characteristics of radionuclide scanning and the clinical findings were approached. Results： There was significant correlation between the severity of alimentary tract hemorrhage and the morbidity of the ulcer and hemorrhage in diverticula in the patients with MD resulted from ectope gastric mucosa （rp = 0.68, P （0.01）, and a significantly negtive correlation between the severity of alimentary tract hemorrhage and the imaging time of the largest diameters in 99mTcO4^ - imaging （rp = - 0.57, P 〈0.05）. However, no significant difference was found between the severity of alimentary tract hemorrhage and the largest diameters in 99mTcO4^- imaging （rp = 0. 32, P〉0. 05）. Conclusion： Ectope gastric mucosa＇s 99mTcO4^- SPECT should be an optimization on the diagnosis of MD with ectope gastric mucosa, for its high sensitivity and the positive predictive value, in addition to its economical and noninvasive property. The ucler or hemorrhage in MD is the most frequent reason of alimentary tract hemorrhage in patients with MD with ectope gastric mucosa, and may play an important role in the advance of imaging time of th
