Investigation on the effect of reference or calibration scans needed to reconstruct undersampled MRI data. The study covers 3 different acceleration factors, and 6 different reference acquisitions. It is found that scan to scan variability for common acceleration factors is larger than any difference in tSNR between FLASH and FLEET, and that segmented EPI and single-shot are inferior to FLASH and FLEET acquisitions.
