摘　　要：采用 99m锝 -高锝酸盐 (99m Tc O4- )对 5例美克耳憩室患儿进行腹部 SPECT显像 ,探讨其在美克耳憩室诊断中的价值。该 5例患儿中 ,2例平面显像未见异常 ,3例在下腹部出现模棱两可的微弱放射性浓聚区 ,经 SPECT显像后始明确美克耳憩室诊断 ,并经手术和病理证实为美克耳憩室伴异位胃粘膜。因此 ,对于临床怀疑美克耳憩室而平面显像阴性或下腹部出现模棱两可的放射性核素浓聚区时 ,进行 SPECT显像具有重要的临床意义。This study was aimed to assess the value of SPECT imaging in the diagnosis of Meckel's diverticulum. 99m TcO 4 - abdominal planar imaging and scintigraphy were performed on 5 hospitalized children with a history of gastrointestinal hemorrhage and abdominal pain. 2 cases were negative on planar imaging and 3 cases showed equivocal 99m TcO 4 - concentration in the lower abdomen, but we could not make out diagnosis. SPECT imaging confirmed there was a remarkable and focal area of increased concentration of 99m TcO 4 - in the lower abdomen in all 5 cases. Operation and pathology confirmed the existence of Meckel's diverticulum with ectopic gastric mucosa. We suggest that SPECT be performed if there is a high index of clinical suspicion for Meckel's diverticulum and the results of planar imaging are equivocal or even normal.
