Evolution of MR Contrast Enhancement Patterns During the First Week after Acute Ischemic Stroke AJNR 22:103-111, Karonen,J.O.,et al, 2001 See this aricle in Pubmed Article Abstract Intravascular and parenchymal enhancement have been detected with contrast-enhanced T1-weighted MR imaging in patients with ischemic stroke. Diffusion-weighted MR imaging depicts infarct within minutes after the onset of symptoms. The aims of this study were to study the different MR enhancement findings during the first week after stroke and to ascertain whether the presence of intravascular enhancement over a larger area than the infarct on diffusion-weighted images on day 1 is able to p redict substantial infarct growth during the first week. Detection of different patterns of contrast enhancement can help in determining the age of infarct. Parenchymal enhancement may be intense and can cause diagnostic uncertainty in cases in which th e clinical history is obscure.
