摘要
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 。
Objective To investigate the value of multi-slice spiral computed tomography (MSCT) in diagnosing gastric cancer. Methods The MSCT signs of 48 gastric cancers proved histologically were evaluated retrospectively. Results The main CT signs included thickening of gastric wall and mass.The lesion showed marked enhancement in the arterial and portal venous phases, and 35 cases showed marked enhancement in the portal venous phase compared with the arterial phase. 12 cases had tumor invasion in the adjacent organs and lymph mode metastasis, and 11 cases had tumor distant metastasis. The accurate rate of enhancement staging was 87 5%. Conclusions MSCT enhancement scan can help us evaluate the lesion more perfectly, and also is helpful in diagnosing and staging of gastric cancer.
