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

Figure 3 The areas under the curve of dynamic contrast-enhanced magnetic resonance imaging parameters for the diagnosis of T stage and differentiation degree. A: The areas under the curve (AUC) of volume transfer constant (Ktran) in the diagnosis of high and low stages; B: The AUC of extravascular extracellular volume fraction (Ve) in the diagnosis of high and low stages; C: The AUC of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters in the diagnosis of high and low stages; D: The AUC of Ktran in the diagnosis of moderate-high and low differentiation; E: The AUC of Ve in the diagnosis of moderate-high and low differentiation; F: The AUC of DCE-MRI parameters in the diagnosis of moderate-high and low differentiation. Ktrans: Volume transfer constant; Kep: Rate constant; Ve: Extravascular extracellular volume fraction; DCE-MRI: Dynamic contrast-enhanced magnetic resonance imaging.
