Radiation damping with inhomogeneous broadening: Limitations of the single bloch vector model

Abstract

There are several examples in the literature where effects of inhomogeneous broadening on radiation damping of free precession signals have been described using a phenomenological 1/T2* term in the Bloch equations. The inappropriate use of this model is illustrated for specific cases. Correct signal shapes are predicted only when isochromat solutions of Bloch's equations are integrated over the spectrum of the inhomogeneous field. © 2001 John Wiley & Sons, Inc.
