The goals of this study were to assess the reproducibility of Dynamic Susceptibility Contrast (DSC) MRI and Perfusion-CT (PCT) and to compare the CBF estimates obtained with DSC, PCT, and Arterial Spin Labeling (ASL). We included patients with cerebral tumor, routinely monitored with these imaging methods. We observed good agreement between DSC and PCT, and poor correlation between DSC and ASL. A more detailed analysis of the present data could yield insights into the respective strengths and weaknesses of each method depending on the vascular properties.
