摘要
目的探讨胃石CT征象。方法回顾性分析2017年7月—2019年2月本院收治并确诊的胃石患者的影像及临床资料,总结胃石的CT征象。入组标准:(1)临床确诊为胃石的病例;(2)胃石在治疗前完成过CT检查。结果共23例患者入组,共发现31枚胃石,其中有4例(共8枚)因胃肠道准备不足发生漏诊。31枚胃石中有22枚胃石呈现"蜂窝征",16枚胃石呈现"粪球征"。"钉耙齿征"和"环水征"均出现在所有胃石中。结论 "钉耙齿征""环水征"是胃石的典型CT征象,较"蜂窝征""粪球征"具有更高的特异性,熟悉这些征象可提高胃石的诊断能力。
Objective To explore MSCT findings of gastric calculir.Methods The image and clinical data of the patientsdiagnosed gastric calculir in our hospital from July 2017 to February 2019 were analyzed retrospectively,and The CT signs of gastric calculir were summarized based on literature.Inclusion criteria were as follows:1.Gastric calculir diagnosis has been confirmed;2.CT examination of the patients had been performed before treatment.Results 23 cases with gastric calculir were studied and a total of 31 stones were found.4 cases( 8 stones) were misdiagnoseddue to insufficient preparation before CT examination.22 gastric calculir in our study showed "honeycomb sign",and 16 gastric calculir displayed "fecal ball sign".Meanwhile,"nail rake tooth sign"and ’"ring water sign"had appeared in all gastric calculir in our study.Conclusions "Nail rake tooth sign"and "ring water sign" are typical CT findings in patients with gastric calculir,and it have higher specificity than "honeycomb sign"and"fecal ball sign".Knowing these signs could improve the diagnostic ability of gastric stone.
