The
aim of this study was to determine the inter-scan reproducibility of
distensibility measurements at the common and internal carotid arteries using
CINE MRI at 3 T. Our results show a good agreement in the area and the
distensibility measurements between the two scans. Furthermore, we compared
the difference in distensibility for both segments of the artery. We found a
significant difference between the common and internal carotid arteries,
suggesting that mechanical modeling of the forces acting on the arterial wall
could be further improved by incorporating the different mechanical
properties of different arterial segments.
