 Abstract: Fitting of spectrally selective CEST contrasts requires models with limiting assumptions. Snapshot CEST allows us to densely sample the Z-spectrum with rapid volumetric imaging within a clinically feasible scan time. With over 60k spectra available per subject, statistically-driven analysis methods are now possible. Here we demonstrate that principle component analysis can be used for model-free analysis of spectral features. Projection of Z-spectra onto principle components from a group of healthy subjects provides several relevant contrasts which reveal anatomical detail and correlate with Gadolinium uptake signatures in a brain tumor patient.
