Abstract

The interleaved-spiral magnetic resonance imaging (MRI) technique was implemented and optimized on a Bruker Biospec 47/30 scanner. The method gives rise to high-resolution images with a time saving factor of up to 8, as compared to the conventional approach. A multifunctional pulse sequence for the fast interleaved-spiral MRI was composed. These functions include spin intensity imaging, transverse relaxation timeT 2 and apparent diffusion-weighted imaging. The method was used to obtain the dynamic responses of a rat brain during ischemia.
