The general procedure of generating tissue contrast
which is characterized predominantly by slow motion by
altering steady state in SWIFT with RAFFn preparation
pulses is described. It is shown that high rotating
frame relaxation contrasts obtained with RAFFn provide
enhanced sensitivity to slow motion in tissue and is
associated with myelin in the brain.
