We combine Rosette Spectroscopic Imaging (RSI), which is a fast, high sensitivity acquisition technique, with LASER , a high performance excitation scheme, and use a 32-channel phased array coil at high field (3T), to achieve high resolution (1cc) 1H MRSI (Magnetic Resonance Spectroscopic Imaging) data in vivo human brain.
