Diffusion-Weighted MR Imaging in the Acute Phase of Transient Ischemic Attacks AJNR 23:77-83,4, Rovira,A.,et al, 2002 See this aricle in Pubmed Article Abstract Two thirds of our TIA patients showed focal abnormalities indicative of acute ischemic lesions on diffusion-weighted images. This incidence is higher than that previously reported in the literature. The presence of such abnormalities incre ased with increasing total symptom duration, but this relation was not observed when only patients whose symptoms lasted less than 6 hours were considered. No significant correlation was observed between the cause and presence of TIA-related lesions on d iffusion-weighted MR images. These TIA-related lesions are probably irreversibly and may lead to subsequent infarct.
