Abstract:
Objective To discuss the application of double contrast enhanced ultrasonography in the diagnosis of micro vessel formation on gastric cancer.Methods 52 cases of patients with gastric cancer who scheduled for elective tumor resection on our hospital from August 2015 to October 2017 were enrolled in the study.Oral ultrasonic contrast agent,and intravenous contrast agent were used to assess the preoperative condition.The image feature of gastric ultrasound imaging was observed,and the time-intensity curve (TIC) parameters of gastric lesions and normal gastric were recorded,the relationship of gastric carcinoma TIC parameters and the expression of micro vessel density (MVD),vascular endothelial growth factor (VEGF) expression were analyzed.Results Comparison of gastric lesions and normal gastric tissue,there were statistically significant difference on the basic strength (BI),enhanced intensity (EI),peak intensity (PI),perfusion time (WIT) (P ＜ 0.05);Correlation analysis showed that EI,PI were positively correlated with MVD,BI,WIT was negatively correlated with MVD (P ＜ 0.05);EI,PI were positively correlated with VEGF,BI was negatively correlated with VEGF (P ＜ 0.05).Conclusions Gastric ultrasound imaging technology can accurately assess the blood perfusion characteristics of gastric carcinoma,with a certain value on the gastric cancer angiogenesis evaluation.
