A method for frequency-selective, high-resolution
acquisition of hyperpolarized substrate and its
downstream metabolites in vivo in 9.4T is presented. The
spatial displacement caused by the chemical shift is
utilized in the acquisition of metabolite-selective
images by modifying the slice-selection gradients
duration and polarity. By doing so, spectral bands of
neighboring resonances can be pushed outside the subject
while acquisition is done in a frequency-interleaved
manner. In this work, a simple implementation of this
concept into a conventional 3D CSI sequence is
presented, along with initial application results from
in vivo mouse kidney experiment in 9.4T.
