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.
