The progress of the magnetic resonance (MR) imaging in the cerebral stroke patients was remarkable, and it became possible to evaluate a brain perfusion or function. Here, we describe about the clinical application of the neuronal tracts and brain perfusion evaluation using 3.0 Tesla MR imaging. The subjects were patients with internal cerebral hemorrhage and major cerebral occlusive diseases. Three dimensional anisotropy contrast (3DAC) imaging and diffusion tensor imaging (DTI) were accepted to estimate the damages of neurnal tracts. Perfusion weighted images with the contrast medium were performed for a quantitative evaluation. The pyramidal tracts were depicted well with 3DAC imaging. Fractional anisotropy (FA) value generated from DTI can predict the outcome of the motor dysfunction in each patient at early stage. Cerebral blood volume calculated from PWI was correlated with and cerebral vascular reserve capacity. 3.0 Tesla MR imaging may develop in cerebral stroke patients in near future.
