The
American Heart Association has deemed the quantification of cerebral
perfusion in stroke to be of paramount importance. Hence accurate automated
determination of perfusion image maps are essential for analyzing the tissue
of risk after an ischemic stroke event.
The need for offline post-processing of Dynamic Susceotibility
Contrast (DSC) images can delay the availability of time critical information
(i.e. the extent of the perfusion diffusion mismatch predicts the response to
intra venous thrombolysis in ischemic stroke) Therefore we have developed a
inline protocol to eliminate the offline generation of quantitative perfusion
maps with evaluation.
