Synopsis

Metabolic imaging of the whole brain is desirable in many neuroscience studies and some clinical applications. This work demonstrates whole-brain MRSI (FOV = 240×240×160 mm³) at 7T using a special SPICE-based data acquisition and processing scheme. Experimental results showed that whole brain metabolic imaging at 3.0×3.0×3.2 mm³ resolution could be obtained in an 8-minute scan at 7T.
