摘要
目的 :评价螺旋CT多期扫描在进展期胃癌术前分期的价值。材料和方法 :前瞻性研究一组36例胃癌病例 ,采用国际胃癌协会通用的TNM标准 ,螺旋CT与手术和病理对照 ,观察螺旋CT对进展期胃癌病变的检出率 ,分期的准确性。结果 :36例进展期胃癌 ,螺旋CT病变检出率100 % ,分期准确性83.33 %(25/30),3例(10 %)CT分期低于外科病理分期 ,2例(6.66 %)CT分期高于外科病理分期。结论 :螺旋CT多期扫描在胃癌术前分期方面有较高的准确性 ,值得临床应用。
Purpose:AIM To evaluate the role of spiral CT in preoperative staging gastric carcinoma.Material and methods:Thirty six cases of gastric carcinoma were prospectively studied by means of triple phase helical CT performed with water as an oral contrast agent.The CT findings were correlated with the surgical and pathological results according to TNM criteria.Results:The detection rate of advanced gastric carcinoma by helieal CT was 100%.25 of 30 patients (83.33%) with advanced gastric carcinoma were correctly staged.Overstaging was noted in 6.66% of cases,and understaging was noted in 10% of cases.Conclusion:These results reveal that spiral CT with water contrast is a valuable tool for determining the staging of gastric carcinoma.
