Main
Stroke is Australia’s second single greatest killer after coronary heart disease and a leading cause of disability.In 2009,
Australians will suffer around 60,000 new and recurrent strokes – that’s one stroke every 10 minutes.One in five people having a first-ever stroke die within one month and one in three die within a year.
In an acute stroke clinical setting what one would like to know is,
Is there hemorrhage and how extensive is the infarct – NCCT
Factors impacting the prognosis
- Duration and severity of occlusion
- Site of occlusion
- Degree of collateralization
- Degree of recanalization
- Re-occlusion
- Sensitivity of tissue to ischemia/Eloquence
The goal of perfusion imaging is to understand stroke evolution
- Predict natural history and outcome without treatment
- To assess effect of treatment on measurable parameters / patient
- To triage patients into those in whom intervention is appropriate and those that should be left alone
- Ultimate goal is to intervene and salvage ischemic but not yet infarcted brain
