Background and Purpose. Duplex scanning is an accepted method for noninvasive
evaluation of carotid stenosis. However, the ultrasound criteria used for the detection of …

Calcification of the internal carotid artery (ICA) hinders accurate evaluation of the stenosis by
conventional ultrasonography due to acoustic shadow. We examined the relationship …

Using ultrasound, we investigated whether carotid parameters differed among subtypes of
ischemic stroke and evaluated the usefulness of these parameters in discriminating among …

Background: Plaques in blood vessels exhibit a wide range of stiffness depending on
disease conditions: stiffness is an important factor in plaque behavior. The geometrical …

Objectives This study clarified the usefulness of carotid duplex ultrasound (CDU) in
evaluating large vessel occlusion (LVO) in patients with acute stroke planned to be treated …

Purpose The Society of Radiologists in Ultrasound (SRU) consensus panel proposed six
Doppler velocity cut points for classifying internal carotid artery (ICA) stenosis of 50% and …

Background and Purpose—To evaluate duplex ultrasonographic thresholds for the
determination of 70% to 99% stenosis of the ipsilateral and contralateral internal carotid …

Background and Purpose: The purpose of this study is to evaluate whether release of
inflammatory markers locally from an atherosclerotic plaque after carotid artery stenting …

Purpose The ratio of the internal carotid artery (ICA) to the common carotid artery (CCA),
especially the “AcT ratio,” which is a modified measurement method of acceleration time, is …

BACKGROUND: Blood flow in stenotic vessels strongly influences the progression of
vascular diseases. Plaques in stenotic blood vessels vary in stiffness, which influences …
