Comparison of dynamic contrast-enhanced-magnetic resonance imaging parameters and serum markers in preoperative rectal cancer evaluation: Combined diagnostic value

The combined application of DCE-MRI functional parameters and serum tumor markers can significantly improve the diagnostic accuracy of T staging and differentiation degree of rectal cancer, providing a new approach to improve the preoperative assessment system of rectal cancer. This combined diagnostic model has important clinical application value, but further validation is needed through large-scale multicenter studies.
