Figure 1From: Correlating lesion size and location to deficits after ischemic stroke: the influence of accounting for altered peri-necrotic tissue and incidental silent infarctsExamples of the four regions used to denote differing categories of lesioned tissue. Note that each row of MR images depicts examples from different patients. Region 1 represents the lesion core, Region 2 represents the peri-necrotic tissue, Region 3 represents lesions in the same hemisphere as the index stroke, and Region 4 represents lesions in the hemisphere opposite to Region 1.Back to article page
