1. A method of generating a magnetic resonance image of a biotic structure comprising the steps of: generating a plurality of datasets by modulating a free induction decay of at least some MR detectable nuclei in the biotic structure with a sinusoidally oscillating magnetic field gradient; using the spectroscopic and spatial information present in the acquired signal to approximate a set of instantaneously acquired gradient echoes; and synthesizing images based upon the approximated acquired gradient echoes.
