摘　　要：目的探讨多层螺旋CT三期增强扫描在胃癌诊治中的应用价值。方法回顾性分析36例经手术及/或病理证实的胃癌的多层螺旋CT三期增强扫描图像。结果多层螺旋CT增强扫描动脉期-门静脉期对胃癌的检出与手术或病理符合率100%,而平衡期扫描显著提高了胃癌T分期的准确度,TNM分期准确性为83.3%。结论多层螺旋CT三期增强扫描对胃癌的检出、定性、分期与预后的评估具有独特的优越性。Objective To explore the application of triphase enhanced multi-slice CT in the diagnosis and treatment of gastric cancer. Methods 36 cases of triphase enhanced multi-slice CT images of gastric cancer confirmed by surgery and/or pathology were restrospectively analyzed. Results Detectability of gastric cancer with the arterial- parenchymal phase of enhanced muliti-slice CT and coincidence of surgery or pathology were 100%, the equilibrium phase could improve the accuracy of T-staging of gastric cancer, and the accuracy of TNM staging was 83.3%. Conclusion Triphase enhanced multi-slice CT is recommended for the detection, qualitation, staging and prognosic appraisal of gastric cancer.
