目的 通过分析胃前壁癌肿在双对比造影 (DC)中的X线征象 ,提高对其影像特征的认识。方法 复查分析经术前、手术和病理证实 ,均做了DC的胃前壁癌肿 3 5例。结果 悬滴、白雾状影、重叠白线及线征 4个征象的出现率分别达 78%、94%、66%、88%。当癌肿累及大小弯侧时 ,还可出现腔壁多边征。如能确定上述征象中的 1、2个对诊断有重要意义。结论 胃前壁癌肿在DC中有其特征性的影像表现 ,注意观察并充分认识上述征象及其周围组织结构的变化 ,并紧密结合临床综合分析 ,有助于提高术前诊断的准确性。
OBJECTIVE: To improve the understanding of the imaging features by analyzing the X-ray findings of gastric anterior wall cancer in double contrast radiography (DC). Methods Retrospective analysis of preoperative, surgical and pathological confirmed, were done DC anterior wall cancer in 35 cases. Results The appearance rate of 4 signs such as hanging drop, white fog shadow, overlapping white line and line sign were 78%, 94%, 66% and 88% respectively.
