Fig 3. A, Graphs show correlations between sonographic and MR phase-contrast volume measurement values for internal carotid arteries. Most of flow measurements are near the line of equality indicating that BFI provides similar blood volume estimates with MR phase-contrast quantification (BFBV = blood-flow volume obtained with B-flow; MRBV = blood-flow volume obtained with MR phase-contrast imaging).
B, Correlation between flow volume measurements of internal carotid arteries obtained with CDI versus MR phase-contrast imaging is shown as scatter plot (CDBV = blood-flow volume obtained with color Doppler).
C, Correlation between flow volume measurements of internal carotid arteries obtained with PDI versus MR phase-contrast imaging is shown as scatter plot. (PDBV = blood-flow volume obtained with power Doppler).
