The fast Pad transform can be used to create NMR spectra from truncated free induction decay (FID) signals at high spectral resolution that would require long readout times for conventional Fourier transform reconstruction. The capability to create high resolution spectra from short truncated FIDs with the Pad transform enables spectroscopy with short TR, low flip angle, and rapid acquisition, potentially yielding SNR improvements by optimization of SNR efficiency. We investigate the SNR gains that are possible using the fast Pad transform to shorten the required readout time for high resolution spectra, within the parameters of a typical brain spectroscopy experiment.
