BACKGROUND AND PURPOSE Serial study of such MR parameters as diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC), ADC with fluid-attenuated inversion recovery (ADC(FLAIR)), and T2-weighted imaging may provide information on the pathophysiological mechanisms of acute ischemic stroke. Our goals were to establish the natural evolution of MR(More)
OBJECTIVE To report neuroimaging findings in patients with complex partial status epilepticus. BACKGROUND During status epilepticus, neuroimaging may be used to exclude other neurologic conditions. Therefore, it is important to identify the neuroimaging features that are associated with status epilepticus. In addition, MRI characteristics may provide(More)
BACKGROUND Knowledge of the natural evolution of ischemic brain lesions may be a crucial aspect in the assessment of future stroke therapies. OBJECTIVE To establish daily changes of ischemic cerebral lesion volume using diffusion-weighted magnetic resonance imaging. DESIGN Prospective cohort study. SETTING Referral center. PATIENTS AND METHODS(More)
OBJECTIVE To determine whether diffusion-weighted imaging (DWI) could identify potentially clinically relevant findings in patients presenting more than 6 hours after stroke onset when compared with conventional MRI. METHODS MRI with both conventional (T2 and proton density images) and echoplanar imaging (DWI and apparent diffusion coefficient maps) was(More)
Most studies of depression after stroke have included heterogeneous samples of patients. These studies have generally not qualified patients as to age, absence of neurologic, psychiatric, and substance abuse histories, and other complicating factors. Of 155 inpatient rehabilitation admissions after acute unilateral cerebrovascular accident, only 26 met the(More)
