摘要: 目的：探讨多层螺旋CT(MSCT)三期增强扫描和使用水作对比剂在胃癌诊断和T分期中的价值。方法: 56例经胃镜证实或怀疑为胃癌的病人均于术前1周内行多层螺旋CT检查。分析多层螺旋CT检查结果，并与术后病理结果进行对照分析。结果：多层螺旋CT三期增强扫描和使用水作充盈剂可发现和正确定位所有进展期胃癌患者。MSCT对胃癌T分期的正确率为73%(41/56),判断浆膜侵犯的正确率、敏感性和特异度分别为89.0%、89.7%和82.0%。结论：多层螺旋CT三期增强扫描对胃癌的显示率高。T分期对指导胃癌手术方式和判断预后具有重要意义。关键词: 胃肿瘤； T分期； MSCT

Abstract： Objective: To analyze CT finding of advanced gastric carcinoma on MSCT to evaluate the utility of triphase contrast enhancement technique with water opacyfied gastrointestinal ducts on the preoperative staging of gastric cancers. Methods: Fiftysix consecutive patients with endoscopic confirmed or clinical suspected gastric carcinoma were preoperatively evaluated with MSCT using the water filling gastrointestine. Each case was staged according to the TNM classification system. All patients subsequently underwent surgery and got pathological results. Features of MSCT were compared with histologic staging of tumor invasion depth. Results: MSCT has detected all the 56 gastric lesions. Compared with histologic results, MSCT achieved correct T staging in 41 patients (73%).The accuracy、 sensitivity and specificity of MSCT for diagnosing involvement of tunica serosal were 89%, 89.7% and 82%, respectively. Conclusions: The detection rate of triphasic enhanced MSCT to gastric carcinoma is very high. MSCT plays an important role in guiding surgical treatment especially after T staging. ......
