摘要 目的分析和探讨低张水充盈螺旋CT平扫加增强扫描在进展期胃肿瘤诊断中的价值,评价其临床意义。方法检查前10h禁食,检查前20min肌注654-210mg,扫描前10min口服温开水1000~1200mL,临扫前再口服水500mL,均行CT平扫加增强扫描,分析CT检查显示病变的优势与局限性。结果对33例经胃镜和(或)手术病理证实的进展期胃癌进行回顾性分析,总结出进展期胃癌低张水充盈螺旋CT平扫加增强检查的直接征象、对周围脏器的侵犯征象和转移征象。结论低张水充盈螺旋CT增强扫描在进展期胃癌腔内和腔外肿块的鉴别、胃壁受浸润的程度、浆膜外侵犯的程度以及有无远处及腹腔淋巴结有无转移、术前分期与评估、手术后复发的判断等方面,均有较高的诊断价值,对临床制定手术方案具有重要的指导意义。
