目的 探讨多层螺旋CT对胃癌的诊断价值。方法 回顾分析 48例经病理证实的胃癌多层螺旋CT表现。结果 主要CT征象为胃壁增厚僵硬、肿块。动脉期及门静脉期病变明显强化 ,3 5例以门静脉期更著 ;周围脏器浸润和淋巴结转移各 12例 ,远处转移 11例 ;增强分期准确性 87 5 %。结论 多层螺旋增强可对胃癌作出更为完善的评价 ,有助于胃癌的诊断及分期
Objective To investigate the diagnostic value of multi-slice spiral CT in gastric cancer. Methods Retrospective analysis of 48 cases of pathologically confirmed multi-slice spiral CT of gastric cancer. Results The main CT signs of thickening of the stomach wall stiffness, mass. In the arterial phase and portal vein phase, the lesions were significantly enhanced. Thirty-five cases had more portal venous phase. Peripheral organ infiltration and lymph node metastasis were observed in 12 cases and distant metastasis in 11 cases. The accuracy of staging was 87.5%. Conclusions Multi-slice helical enhancement can make a more complete evaluation of gastric cancer and contribute to the diagnosis and staging of gastric cancer
