The iMSDE sequence provides outstanding blood suppression efficiency and time efficiency. Thus, this new pulse sequence has the potential to become a noninvasive alternative to DSA for quantitative carotid vascular morphology evaluation. This study sought to evaluate the clinical value of the iMSDE techniques in atherosclerotic carotid artery assessment in 29 subjects before carotid endarterectomy (CEA) and carotid artery stenting(CAS), by comparing with DSA. It was found that the iMSDE sequence demonstrated a good consistency with DSA in defining the location and shape of the advanced plaques. Additionally, the iMSDE sequence has the advantage of accurately depicting early atherosclerotic lesions, which can be beneficial for clinical treatment planning.
