摘　　要：目的:探讨胃窗超声造影与增强CT对胃癌病理类型判断的影响因素。方法:选择120例经过手术病理证实的胃癌患者,均进行胃窗超声造影剂增强CT检查。所有患者都进行了临床资料的调查,分析了影响病理类型判断的影响因素。结果:胃癌患者超声造影显示为胃窦部胃壁增厚、僵硬,呈低回声,与周围组织分界不清;CT表现为胃壁均质不规则增厚,强化后扫描病灶呈均质轻、中度强化;随着临床分期的增加,高分期患者的PI值明显低于低分期患者,而EI值明显高于低分期患者(P<0.05)。超声造影与增强CT诊断胃癌都为112例,检出率为93.3%。Logistic回归分析显示患者的发病年龄及胃癌的病灶部位、临床分期、病理组织学类型是胃癌检出的独立危险因素(P<0.05)。结论:胃窗超声造影与增强CT在胃癌病理判断中都有很好的效果,可明显提高病变诊断的准确性,但是也需要根据影响因素加强鉴别。Objective： To investigate the effect factors of stomach window CEUS and enhanced CT for the diagnosis of gastric pathology type. Methods： 20 cases with gastric cancer who were confirmed by the surgical and pathology were selected as the study objectives and were examined by the stomach windows ultrasound contrast and the agent-enhanced CT. All the clinical data of patients were investigated, and the influencing factors of pathology type＇judgment were analyzed. Results： CEUS results showed that the antral gastric wall thickening and inflexible, hypoechoic and unclear boundaries with the surrounding tissue were the influencing factors of patients with gastric cancer. CT results reflected that the homogeneous irregular thickening of the gastric wall was the influencing factor, after which the enhanced scan showed a homogeneous lesions with mild to moderate strengthening. With the clinical stage increasing, PI value of high installment patients were obviously lower than that of the low installment patients, while the EI value were obviously higher than that of the lower installment patients （P〈0.05）. The diagnosis cases were 112 both by the CUES and the enhanced CT with the detection rate 93.3%. Logistic regression analysis performed that the onset age, the gastric lesion site, the clinical pathology and the histological types were the independent risk factors （P〈0.05）. Conclusion： Stomach CUES and contrast-enhanced CT in the gastric pathology type judgment had good effect, which could improve the disease diagnose accuracy, but also required intensified identification based on effect factors.
