STIMULATED ECHOES AND SPIN ECHOES - SIMULTANEOUS DETERMINATION OF T(2), DIFFUSION-COEFFICIENT, AND RF HOMOGENEITY

By comparing information encoded in multiple signals it is possible to measure several sample-dependent parameters in a single experiment with the advantages that the measurements are less susceptible to changes in the sample over the course of an experiment and the total experiment time is reduced. An imaging sequence is presented that allows simultaneous determination of the spatial variation in RF field strength, T2 relaxation rate, and a combination of T1 and diffusion coefficient. This sequence can be extended to provide information on other parameters such as chemical shift or flow. © 1993 Academic Press. All rights reserved.
