Clinical Study of Multi-slice Spiral CT Post-processing Technology in the Evaluation of Gastric Cancer Image
Gastric cancer is the most common malignant tumor in the digestive system. At present, surgical resection is the most effective treatment. The prognosis is closely related to the degree of tumor differentiation, depth of invasion, TNM stage and so on. Accurate preoperative evaluation of gastric cancer patients is conducive to the selection of effective treatment and prolongation of survival. This paper discusses the feasibility of multi-slice spiral CT (MSCT) in perfusion imaging of gastric cancer, and evaluates its application value in preoperative evaluation of gastric cancer. The difference of PS, MTT, BF and bv in different TNM stages was statistically significant (P <0.05). MSCT perfusion imaging can reflect the hemodynamic changes of gastric cancer, which is of great significance for preoperative evaluation of gastric cancer.
