Enhancement degree of brain metastases: correlation analysis between enhanced T2 FLAIR and vascular permeability parameters of dynamic contrast-enhanced MRI

ConclusionsThe enhancement degree of brain metastases on CE-T2 FLAIR is negatively correlated with Ktrans and Kep values, which indicate that vascular permeability parameters may play an important role in explaining the difference in enhancement between CE-T2 FLAIR and CE-BRAVO.Key Points• The enhancement degree on CE-T2 FLAIR was negatively correlated with Ktransand Kepvalues.• The vascular permeability of brain metastasis accounted for the difference in enhancement degree between CE-T2 FLAIR and CE-BRAVO.• CE-T2 FLAIR is useful for detecting brain metastases with mild disruption of the blood-brain barrier.
