目的 探讨胃癌螺旋CT的TNM分期诊断价值。资料与方法 5 0例经胃镜证实的胃癌患者进行低张服水螺旋CT扫描。根据胃癌的部位、大小、范围、浸润程度、周围淋巴结及脏器转移情况进行TNM分期 ,并与术后病理分期对照。结果 低张服水螺旋CT对胃癌TNM分期准确性为 76 %,其中T分期准确性为 78%,N分期准确性为 6 2 %,M分期准确性为 96 %。结论 低张服水螺旋CT检查的TNM分期对评估胃癌的手术方案及临床治疗有较大的价值。
Objective To investigate the TNM staging of gastric cancer spiral CT. Materials and Methods 50 cases of gastric cancer patients confirmed by gastroscope underwent hypotonic service water spiral CT scan. According to the location of gastric cancer, size, extent, degree of infiltration, peripheral lymph nodes and organ metastasis of TNM staging, and postoperative pathological staging. Results The staging accuracy of TNM staging was 76%. The accuracy of T staging was 78%, the accuracy of N staging was 62%, and the accuracy of M staging was 96%. Conclusion The TNM staging of low-tension service water spiral CT examination has great value in the evaluation of surgical treatment and clinical treatment of gastric cancer.
