Diffusion weighted MR imaging became widely accepted as reliable method for the diagnosis of brain ischemia early after stroke onset. Single-shot spin echo echoplanar imaging is most commonly used for acquisition of diffusion weighted scans but relatively low resolution, low SNR and bulk susceptibility artifacts decrease their diagnostic value. A promising new scan technique (`BLADE` DWI) is now available for diffusion imaging using a fast spin echo sequence (FSE) with radial k-space sampling that could help overcome susceptibility artifacts. A FSE BLADE diffusion weighted imaging was evaluated at 3 T in combination with a 32-channel head coil in this study.
