A spatiotemporal spectral analysis is presented of kt-space in cine images in the presence of several types of cardiac motion. The temporal spectral content of each k-space view is quantified by a single spectral coefficient. Paradoxically, comparison of these coefficients between k-space views for phantom simulation data and in short-axis cardiac MRI data reveals greater relative changes in high spatial frequencies than in low spatial frequencies.
