MEASUREMENT OF ONE-DIMENSIONAL SPATIALLY-RESOLVED SELF-DIFFUSION COEFFICIENTS AND LONGITUDINAL RELAXATION-TIMES WITH A SINGLE B-1 GRADIENT

A very simple experimental setup, involving a single coil for generating a radiofrequency field gradient, enables one to determine the self-diffusion coefficient and the longitudinal relaxation time along the gradient axis. This is accomplished by a two-dimensional experiment involving three gradient pulses. The first part of the sequence includes two pulses of identical duration separated by an evolution interval which, by proper phase cycling, encodes longitudinal magnetization according to translational diffusion. The last pulse is incremented for purposes of spatial encoding. (C) 1995 Academic Press, Inc.
