Fig. 3From: Intensity of arterial structure acquired by Silent MRA estimates cerebral blood flowComparisons of flow shapes generated by Silent MRA and 2D PC-MRA. The laminar flow shapes of the 13 cerebral arteries of one study participant (33-years-old; man) are similar whether generated by 2D PC-MRA or Silent MRA. The variable R is the correlation coefficient between the phase distribution (in 2D PC-MRA) and signal intensity (in Silent MRA)Back to article page
