Investigating the role of spectral CT combined with MSI status in the diagnosis and treatment of colorectal cancer lymph nodes.
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.
Study summary
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.
