A prospectively gated free-breathing renal BOLD sequence was compared to conventional breath hold renal BOLD. The new sequence gives consistently better SNR than the conventional sequence. RMS error of T2* estimation was investigated as a measure of accuracy. The free-breathing renal BOLD sequence allows flexible tradeoff of imaging time with SNR and can improve the accuracy of renal BOLD T2* estimation.
