Inter-slice Variations of Intensity-time-curves in Arteries and Veins.

<p>(a) The dynamic intensity-time-curves (ITCs) in artery voxels for image slices. Severe in-flow effect resulted in the inter-slice ITC differences. (b) The dynamic ITCs in vein voxels for image slices. Inter-slice ITC differences were moderate due to the reduced in-flow effect in veins. (c) The baseline and peak intensities in arteries and veins for image slices. The baseline intensity in arteries decreased by a factor of two with the ascending image slices.
