Previous study has demonstrated the feasibility of
single breath-hold renal perfusion imaging using FAIR
ss-FSE at 7T. Without short-term specific absorption
rate issue, 3T may provide similar imaging quality for
the single breath-hold perfusion imaging as 7T by using
a shorter TR and a larger number of label and control
images. Such a hypothesis has been disapproved by both
theoretical and experimental study results.
