Perfusion parameters
CBF
Reduction estimates infarct core.
CBV
Preserved CBV with delayed Tmax suggests salvageable tissue.
MTT
Sensitive but nonspecific marker of hypoperfusion.
Tmax
Primary parameter used to estimate penumbra.
TTP
Supportive parameter; less commonly used for treatment decisions.
Perfusion pattern
Infarct territory
