Those patients most likely to show evidence of brain injury on MR diffusion-weighted imaging (DWI) are patients who have motor symptoms or whose symptoms last longer (i.e., a mean 60 minutes compared with a mean 30 minutes among patients whose imaging studies are negative for brain injury).1 The findings were the work of the MRI in TIA Collaborative Group, a multi-institutional international endeavor.
