Abstract Fractional flow reserve (FFR) computed from computed tomography
angiography (CTA), i.e., FFRCT has been used in the clinic as a noninvasive parameter for
functional assessment of coronary artery stenosis. It has also been suggested to be used in
the assessment of carotid artery stenosis. The wall thickness of the vessel is an important
parameter when establishing a fluid-structure coupling model of carotid stenosis. This
work studies the effect of the vessel wall thickness on hemodynamic parameters such as
FFRCT in carotid stenosis. Models of carotid stenosis are established based on CTA image
data using computer-aided design software. It is assumed… More >
