Statistically significant differences from baseline (P < 0.017).
CI, confidence interval; DCE-MRI, dynamic contrast-enhanced magnetic resonance imaging; C, continuous; I, intermittent; IAUC60, area under the plasma concentration–time curve for the first 60 s postcontrast agent injection; Ktrans, transfer constant.
