Preoperative SPECT/CT fusion imaging in localization of ectopic gastric mucosa surgery / 中国医学影像技术

ABSTRACT

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 min of the dynamic planar imaging underwent SPECT/CT and image fusion at the end of 20 min.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.
