Synopsis
This study investigated to what extent blood-brain barrier (BBB) leakage (1) can be measured with DSC-MRI and (2) is influenced by perfusion. In vivo DCE (golden-standard) and DSC data of patients with cerebral small vessel disease (cSVD) and elderly controls were used, as well as simulations of signal curves. DSC-MRI, in contrast to DCE-MRI, is not sensitive enough to measure subtle leakage in cSVD. Further research is required to better disentangle perfusion effects from leakage, and therefore correction methods should be used with caution for measuring subtle leakage.
