From: Repeatability and internal consistency of abdominal 2D and 4D PC MR flow measurements
A. Average absolute and percent total flow differences for 2D and 4D PC flow measurements. Flow differences were computed as the difference between suprarenal aortic flow (Qin) and the sum of the flow in the infrarenal aorta and two renal arteries (Qout). Measurements were normalized by the average of these two values. Bars are standard deviation. B. Bland-Altman plots for the repeatability of 2D and 4D flow difference measurements.
