Overview
MR perfusion complements diffusion imaging to estimate ischemic core and salvageable penumbra for reperfusion decisions.
Core Sequences
Include diffusion weighted imaging perfusion weighted imaging and MR angiography for vessel status assessment.
Acquisition and Postprocessing
Use dynamic susceptibility contrast techniques with standardized deconvolution to derive cerebral blood flow and volume maps.
Clinical Integration
Interpret perfusion maps alongside clinical timeline and vessel imaging to guide thrombolysis and thrombectomy decisions.
