A quantitative MRI method for imaging blood-brain barrier leakage in experimental traumatic brain injury. [PDF]

PLoS ONE, 2014
Blood-brain barrier (BBB) disruption is common following traumatic brain injury (TBI). Dynamic contrast enhanced (DCE) MRI can longitudinally measure the transport coefficient Ktrans which reflects BBB permeability.
