AIM Ultrasound protocols to measure carotid intima media thickness (CIMT) differ considerably with regard to the inclusion of the number of carotid segments and angles used. Detailed information on the completeness of CIMT information is often lacking in published reports, and at most, overall percentages are presented. We therefore decided to study the completeness of CIMT measurements and its...

BACKGROUND AND PURPOSE Diagnosis of Moyamoya disease (MMD) is based on the characteristic angiographic findings. However, differentiating MMD from intracranial atherosclerotic disease (ICAD) is difficult. We compared vessel wall imaging findings on high-resolution magnetic resonance imaging between MMD and ICAD. METHODS High-resolution magnetic resonance imaging was performed on 32 patients w...

The spatial distribution of intimal thickening was determined for each of 42 carotid bifurcations removed at autopsy from patients with no clinical or anatomic evidence of cerebrovascular disease. Both right and left specimens were available for six of the individuals. Each bifurcation was removed intact and included a 1.5-2.9-cm length of the common carotid artery and a 1.5-2.5-cm length of th...

BACKGROUND The observation of an intraluminal common carotid artery thrombus overlying a wall defect at ultrasonography or angiography is unusual. To our knowledge, there are no previous reports of a free-floating thrombus in the common carotid artery. CASE REPORT A 45-year-old woman who was previously healthy and on no medications presented with acute hemiparesis and aphasia. Following testi...

Background A discrete transition of wall stiffness at the interface of a compliant aorta and stiffer carotid arteries creates a reflection site for the aortic pulse wave and consequently limits excessive pulsatile energy transmission towards the brain. Arterial wall stiffness can be expressed by the pulse wave velocity (PWV) and dualslice one-directional through-plane velocity-encoded (VE) MRI ...

Carotid stenting has recently emerged as a potential alternative to surgical treatment. We report a case of a spontaneous rectus sheath hematoma in a patient who underwent anticoagulation therapy following carotid stenting. Computed tomography findings were consistent with active bleeding within the hematoma, and this was confirmed with selective angiography via right deep circumflex iliac arte...

Evaluation of carotid intima media wall thickness (IMT) by using ultrasonography is a validated quantitative method for assessing atherosclerosis, and is closely correlated with pathological findings observed in the carotid artery. Furthermore, the appearance of atherosclerosis in the carotid artery has been highly associated with atherosclerosis in the aorta and a close relationship has been o...

The analysis of the ultrasound carotid artery wall is of highest importance in clinical practice. In fact, the Intima-Media Thickness of carotid artery wall is an indicator for some of the most severe and acute cerebro-vascular pathologies like stroke and heart attack. Ultrasound carotid artery image segmentation is challenging due to the interference from speckle noise and fuzziness of boundar...
