  • Abstract
  • Look Inside

Transparent three-dimensional (3D) visualization of hyperacute cerebral ischemic lesions was reconstructed using parallel volume-rendering algorithm by selecting the high signal intensity area for ischemic lesion and the low signal intensity area for parenchymal margin, respectively, from the volume dataset of echo-planar diffusion-weighted mag-netic resonance imaging (DWI). The 3D DWI can depict the ischemic lesions at the hyperacute stage of cerebral ischemia, transparently through the contours of brain and ventricular structures.
