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).
