摘要
目的探讨SPECT/CT显像术前对异位胃黏膜病灶的定位诊断价值。方法对25例异位胃黏膜患儿进行SPECT/CT检查,对动态平面显像20min内腹部有固定异常放射性浓聚灶者,于20min末行SPECT/CT断层扫描并进行同机断层融合,评价断层融合显像对病灶的定位结果与术中所见的一致性。结果 25例平面显像阳性,其中断层融合显像阳性17例,阴性8例。14例(14/17,82.35%)断层融合显像所示病灶位置与术中所见相同,一致性高(Kappa=0.746,P<0.05)。结论异位胃黏膜SPECT/CT融合显像可准确定位病灶,有较高的应用价值。
Objective To explore the location value of preoperative SPECT/CT fusion imaging in ectopic gastric mucosa lesions. Methods Twenty-five children with ectopic gastric mucosa were examined with SPECT/CT. Patients who had fixed abnormal uptake lesions in abdomen within 20 rain of the dynamic planar imaging underwent SPECT/CT and image fusion at the end of 20 rain. The localization results of lesions by SPECT/CT fusion imaging were compared with intraoperative findings. Results Twenty-five patients with positive planar imaging underwent tomography fusion imaging, and then positive findings were noticed in 17 patients, among them 14 patients＂ intraoperative findings had high consistency with location of lesions of tomography fusion imaging （Kappa= 0. 746, P〈0.05）. Conclusion SPECT/CT fusion imaging can locate ectopic gastric mucosa lesions accurately and has high application value.
