DCE-MRI studies of cervical cancer have reported that Tofts model-derived K trans may predict outcome. Since K trans depends on both microvascular perfusion and permeability, it is unclear whether one or both are important for predicting survival. We present what we believe to be the first prospective DCE-MRI study (n = 42) to employ the more specific two-compartment exchange model (2CXM) to separately measure perfusion (plasma flow) and permeability, and study their relationship to disease-free survival. High plasma flow ( P = 0.022) and low FIGO stage ( P = 0.020) were significant predictors of survival, but permeability was not ( P = 0.63).
