Study on the Prediction of Regional Lymph Node Metastasis in Colorectal Cancer by Spectral CT Combined With MSI

April 27, 2026 updated by: Yunnan Cancer Hospital
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.

Intervention / Treatment
Experimental: 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
Diagnostic test: Investigating the role of spectral CT combined with MSI status in the diagnosis and treatment of colorectal cancer lymph nodes.
The CT scan is part of the standard treatment protocol.
