In this study, we presented a Velocity Selective RF
pulse prepared Inversion Recovery (VSIR) technique for
carotid artery vessel wall imaging. Simulation results
demonstrate the feasibility of VS inversion pulse.
In-vivo experiments showed that VSIR can be used for
carotid vessel wall imaging. VSIR technique provides
better SNR of vessel wall and CNR between lumen and
vessel wall than iMSDE. However, in some cases that flow
is not exactly along the velocity encoding direction,
such as BIFU and ICA, VS sacrifices blood suppression
efficiency. More applications on other vascular bed such
as femoral artery will be evaluated in further study.
