METHODS FOR SPATIAL AND SPECTRAL SELECTIVITY IN MAGNETIC RESONANCE IMAGING AND SPECTROSCOPY

摘要

The present invention provides magnetic resonance multidimensional selectivity based on spatiotemporal encoding (SPEN). In particular, multidimensional selectivity is achieved by the concurrent application of frequency-swept irradiation and magnetic field gradients for the sequential manipulation of spins in space in one dimension or more. Simultaneous spatial and spectral selectivity is disclosed.
