One of the first questions asked by stroke patients and their families at admission is if and how soon they can expect improvement in their functional deficits. The ability to quantify the likelihood of such improvement could therefore be of great clinical interest. Important prognostic variables in current clinical practice include the admission NIH Stroke Scale (NIHSS) score and admission “core infarct” lesion volume on magnetic resonance diffusion-weighted imaging (DWI). However, admission infarct volume and clinical stroke severity alone can only predict 30% to 50% of the variance in motor impairment improvement; thus a predictive model may also include information regarding the infarction location, structural integrity of descending motor pathways, and cortical activation in fMRI studies. The accuracy of such prognostication might be improved with the addition of kinetic cerebral perfusion parameters to predictive models. Whereas acute DWI lesions are highly specific for infarction, perfusion scans can provide complementary information by detecting regions of severely impaired blood flow with high probability of infarction. The precise spatial localization of cerebral hypoperfusion can substantially contribute to the accuracy of predictive models of stroke outcome, especially when used in combination with other clinical information. In present study, we combined admission clinical and topographic hemodynamic imaging data to develop prognostic models for prediction of early functional improvement in acute stroke patients presenting with single extremity motor deficits. An automated location-weighted atlas-based methodology was used to quantify the effects of the complex spatial pattern of admission cerebral perfusion deficits on early functional outcome.
