Diagnostic performance of dynamic contrast-enhanced magnetic resonance imaging parameters and serum tumor markers in rectal carcinoma prognosis

Figure 4 The areas under the curve of dynamic contrast-enhanced magnetic resonance imaging parameters, carbohydrate antigen 19-9 and carbohydrate antigen 125 for the diagnosis of T stage and differentiation degree. A: The areas under the curve (AUC) of carbohydrate antigen 19-9 (CA19-9) in the diagnosis of high and low stages; B: The AUC of CA125 in the diagnosis of high and low stages; C: The AUC of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters plus tumor markers in the diagnosis of high and low stages; D: The AUC of CA19-9 in the diagnosis of moderate-high and low differentiation; E: The AUC of CA19-9 in the diagnosis of moderate-high and low differentiation; F: The AUC of DCE-MRI parameters plus tumor markers in the diagnosis of moderate-high and low differentiation. CA19-9: Carbohydrate antigen 199; CA125: Carbohydrate antigen 125; DCE-MRI: Dynamic contrast-enhanced magnetic resonance imaging.
