Characterization
of phosphocreatine (or PCr) in biological tissues can provide valuable
information on tissue physiology and metabolism and may lead to sensitive
disease markers. We have developed 2D
and 3D spectrally selective PCr imaging techniques on a human 3T MRI
scanner. Low resolution PCr images
(32x32) can be obtained in 10.8 minutes with an SNR of ~4, boding well for
further developing these techniques for human applications.
