About

Spectral CT was used to prospectively collect medical images and clinical data related to gastric cancer, evaluate the effect of image quality in the diagnosis of gastric cancer, and evaluate the application value in the accurate staging of gastric cancer, so as to provide a more accurate clinical basis for diagnosis, promote the development of individualized treatment, and ultimately improve the prognosis of patients.

The application value of spectral CT in the accurate staging of gastric cancer

Experimental group

Description:

Prospectively collect medical images and clinical data related to gastric cancer using Philips Quark CT equipment, and evaluate the diagnostic accuracy and clinical application value in the accurate staging of gastric cancer.Patients diagnosed with gastric cancer in Yunnan Provincial Cancer Hospital from April 2025 to May 2026 were consecutively included, and after scanning with Philips Quark CT, the TNM stage of gastric cancer patients was assessed by two radiologists, and finally statistical analysis was performed.

Treatment:
