This study uses T1-weighted DCE-MRI to quantify subtle
blood-brain barrier permeability in normal-appearing
white matter and white matter lesions of patients with
mild stroke. We calculated Patlaks pharmacokinetic
parameters and two model-free measurements, all of which
suggest that permeability is enhanced in white matter
lesions when compared to normal-appearing white matter.
Moreover, we investigated the relationship between
model-free and pharmacokinetic parameters, showing
moderate to strong correlations.
