[Abstract] Preoperative assessment of patients with gastric cancer (GC) is critical to their prognosis, which greatly affects the long-term quality of life. Imaging and biological makers, the important parts of preoperative assessment, provide a lot of information for diagnosis and treatment strategy of gastric cancer. The magnetic resonance imaging (MRI) and ki67 occupy an irreplaceable position. MRI can not only evaluate tumor infiltration, but also have unique advantages in the evaluation of lymph node and distant metastasis. Diffusion-weighted imaging (DWI), one of MRI functional imaging, based on its apparent diffusion coefficient (ADC) value, is widely recognized in the evaluation of malignant tumors. ki67 expression index as a prognostic factor for malignant tumors, is closely related to the prognosis of gastric cancer patients. Similarly, postoperative pathological typing is also an important basis for clinicians to make prognosis and chemotherapy regiments. However, there is little research on the relationship among the three aspects, and further research is needed in future.
