简要总结
Spectral CT was used to prospectively collect medical images and clinical data related to colorectal cancer, evaluate the effect of image quality in the diagnosis of colorectal cancer, and evaluate the application value in the accurate staging of colorectal 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.

研究组 & 干预措施
Study on the prediction of regional lymph node metastasis in colorectal cancer by spectral CT combin
Prospectively collect medical images and clinical data related to colorectal cancer using Philips Quark CT equipment, and evaluate the diagnostic accuracy and clinical application value in the accuratestaging of colorectal cancer. Patientsdiagnosed with colorectal cancer in Yunnan Provincial Cancer Hospital from August 2025 to December 2026 were consecutively included,and after scanning with Philips Quark CT, the TNM stage of colorectal cancer patients was assessed by two radiologists, and finally statistical analysis was performed
干预措施: Investigating the role of spectral CT combined with MSI status in the diagnosis and treatment of colorectal cancer lymph nodes. (Diagnostic Test)
结局指标
主要结局
Pathological TNM staging
时间窗: 1 day
Pathological examination information: The pathology results using surgery/biopsy data are the gold standard, and the depth of tumor invasion, lymph node metastasis, and distant metastasis are recorded
