【摘要】 目的探讨99TcmO-4平面显像联合SPECT/CT断层显像在肠道异位胃粘膜诊断中的增益价值。方法 33例患儿行99TcmO-4异位胃粘膜平面显像,26例行平面显像联合SPECT/CT局部断层显像,以临床结果进行为评价标准,评价断层显像在异位胃粘膜显像中增益价值。结果在所有59例患儿的显像中,33例动态平面异位胃粘膜显像的灵敏度、特异度及正确性分别为66.67%、33.33%、54.55%;而平面显像联合断层显像的灵敏度、特异度及正确性分别为85.71%、91.67%、88.46%,两组间的灵敏度没有统计学差异,特异度及正确率有统计学差异。结论99TcmO-4异位胃粘膜平面显像联合SPECT/CT断层显像能明显提高诊断的特异性及正确性,减少临床不必要的手术治疗。更多还原

【Abstract】 Objective To investigate the extra value of99TcmO-4planar imaging combined SPECT / CT tomography imaging in the diagnosis of ectopic gastric mucosa. Methods99TcmO-4planar imaging and99TcmO-4planar imaging combined SPECT / CT tomography imaging were performed separately on 33 and 26 children suspected ectopic gastric mucosa. The extra value of SPECT / CT tomography imaging was evaluated in the diagnosis of ectopic gastric mucosa by referring to clinical result. Results In all 59 cases,the sensitivity,specificity and accuracy rate of99TcmO-4planar imaging vs99TcmO-4planar imaging combined SPECT / CT tomography imaging in the diagnosis of ectopic gastric mucosa are 66. 67%,33. 33%,54. 55% vs 85. 71%,91. 67%,88. 46% respectively. The specificity and accuracy rate between the two groups were significantly different while sensitivity was not statistically significant. Conclusion The99TcmO-4planar imaging combined SPECT / CT tomography imaging may improve the specificity and accuracy in the diagnosis of ectopic gastric mucosa and reduce unnecessary surgical treatment.更多还原
