Figure 2From: Inter-study reproducibility of interleaved spiral phase velocity mapping of renal artery haemodynamicsInter-observer (a) and inter-study (b) Bland Altman plots of RI (resistive index), PI (pulsatility index) and RABF (renal artery blood flow) per kidney in 10 healthy volunteers. For each plot, the horizontal lines show the mean difference and the 95% limits of agreement (mean +/- 2SD) between observers (a) or between scanning sessions (b).Back to article page
