Pilot study finds good correlation between volume transfer constants from WEPCAST and DCE-MRI in clinical subjects, highlighting a non-invasive option for blood-brain barrier assessment.
There is an unmet need of a non-invasive technique to compute the water exchange between vascular and extra-vascular space in the brain since blood brain barrier (BBB) disruption is common in many pathologies and the state of art exogenous contrast agent based method cann’t be applied to all clinical population. So, the current study is aimed at computing a volume transfer constant (Ktrans) from water-extraction-with-phase-contrast-arterial-spin-labelling (WEPCAST) method and to compare it with the global Ktrans from DCE-MRI data. Results of the study finds a good correlation between Ktrans computed from WEPCAST and DCE-MRI data.
