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.
