- Abstract
- We report on three patients with transient focal neurologic deficits that completely resolved. In all cases, initial
perfusion-weighted imaging (PWI) performed 1 hour after being free of symptoms showed a defect in the time-to-peak
(TTP) map in the area with normal diffusion-weight imaging (DWI) findings. After 24 hours, DWI showed a high signal
intensity in exactly the same area as the TTP defect. Therefore, early PWI provides a rapid evaluation of cerebral
hemodynamics in transient ischemic attack. Key Words: Ischemic attack, transient, MRI, perfusion-weighted imaging
