Compared with conventional angiogram-guided procedure, intravascular imaging modalities give us a lot of useful information to make the procedure better. Intravascular imaging modalities give us the information about lesion characters, reference vessel diameter and the interaction between the stent strut and the plaque such as stent strut malapposition or plaquqe prolapse in real time during the procedure. We can change our strategy according to these information. Intravascular ultrasound (IVUS) is a most common intravasculr imaging modality during CAS in these days...

BACKGROUND: Alterations of glucose metabolism represent well known risk factors for the atherosclerotic process and then for cardiovascular disease. OBJECTIVE: to investigate the association between fasting glucose and early signs of atherosclerosis, by means of carotid intima-media thickness (c-IMT) in a population of apparently healthy overweight/obese subjects. In addition, we evaluated the possible existence of a glycemic threshold above which the risk of atherosclerosis significantly increases...

Stroke risk stratification based on grayscale morphology of the ultrasound carotid wall has recently been shown to have a promise in classification of high risk versus low risk plaque or symptomatic versus asymptomatic plaques. In previous studies, this stratification has been mainly based on analysis of the far wall of the carotid artery. Due to the multifocal nature of atherosclerotic disease, the plaque growth is not restricted to the far wall alone. This paper presents a new approach for stroke risk assessment by integrating assessment of both the near and far walls of the carotid artery using grayscale morphology of the plaque...

Bone mineral density (BMD) has been suggested to be associated with atherosclerosis. In the present study, we evaluated the association between lumbar BMD and the segments of carotid intima-media thickness (CIMT), a surrogate marker of subclinical atherosclerosis, in Korean adults, with consideration of sex and menopause status. Among 1,679 Korean adults who enrolled in a Healthy Twin Study, 723 men, 690 premenopausal women, and 266 postmenopausal women measured the CIMT at the common carotid artery intima-media thickness (CCA-IMT), carotid bifurcation intima-media thickness (BIF-IMT), internal carotid artery intima-media thickness (ICA-IMT) using B-mode ultrasound and lumbar BMD using dual-energy X-ray absorptiometry...

The axial resolution of ultrasonic imaging is confined by the temporal width of acoustic pulse generated by the transducer, which has a limited bandwidth. Deconvolution can eliminate this effect and, therefore, improve the resolution. However, most ultrasonic imaging methods perform deconvolution scan line by scan line, and therefore the information embedded within the neighbor scan lines is unexplored, especially for those materials with layered structures such as blood vessels. In this paper, a joint sparse representation model is proposed to increase the axial resolution of ultrasonic imaging...

Beamforming (BF) in ultrasound (US) imaging has significant impact on the quality of the final image, controlling its resolution and contrast. Despite its low spatial resolution and contrast, delay-and-sum (DAS) is still extensively used nowadays in clinical applications, due to its real-time capabilities. The most common alternatives are minimum variance (MV) method and its variants, which overcome the drawbacks of DAS, at the cost of higher computational complexity that limits its utilization in real-time applications...

BACKGROUND AND PURPOSE: Atherogenic changes in lipids occur among women around the time of the natural menopause, that is, within 1 year of the final menstrual period (FMP). We investigated whether lipid changes around the FMP are related to carotid intima-media thickness, interadventitial diameter, and plaque in postmenopausal women. METHODS: A total of 863 natural postmenopausal women with no history of heart attack or stroke underwent carotid ultrasound scans at follow-up year 12 or 13 of the Study of Women's Health Across the Nation...

PURPOSE: The previously described 2D standardized vessel-wall-plus-plaque thickness (VWT) maps constructed from 3D ultrasound vessel wall measurements using an arc-length (AL) scaling approach adjusted the geometric variability of carotid arteries and has allowed for the comparisons of VWT distributions in longitudinal and cross-sectional studies. However, this mapping technique did not optimize point correspondence of the carotid arteries investigated. The potential misalignment may lead to errors in point-wise VWT comparisons...

REVIEW
Graham J Fent, John P Greenwood, Sven Plein, Maya H Buch
This review assesses the risk assessment of cardiovascular disease (CVD) in rheumatoid arthritis (RA) and how non-invasive imaging modalities may improve risk stratification in future. RA is common and patients are at greater risk of CVD than the general population. Cardiovascular (CV) risk stratification is recommended in European guidelines for patients at high and very high CV risk in order to commence preventative therapy. Ideally, such an assessment should be carried out immediately after diagnosis and as part of ongoing long-term patient care in order to improve patient outcomes...

Characterization of carotid plaque composition, more specifically the amount of lipid core, fibrous tissue, and calcified tissue, is an important task for the identification of plaques that are prone to rupture, and thus for early risk estima-tion of cardiovascular and cerebrovascular events. Due to its low costs and wide availability, carotid ultrasound has the potential to become the modality of choice for plaque characterization in clinical practice. However, its significant image noise, coupled with the small size of the plaques and their complex appearance, makes it difficult for automated techniques to discriminate be-tween the different plaque constituents...

BACKGROUND: Childhood acute lymphoblastic leukemia (ALL) survivors have increased risk of obesity, metabolic alterations and cardiovascular disease (CVD). Vascular endothelial function has been studied in adult cancers. Limited data exist regarding CVD risk factors among childhood ALL survivors. We aimed to assess endothelial function, metabolic and cardiovascular risk factors in young survivors of childhood ALL. METHODS: Auxological parameters, blood pressure, glucose, lipid profile, hemostatic markers (total adiponectin and high-molecular-weight subfraction, endothelin-1, von Willebrand factor antigen, thrombin-antithrombin complex, D-dimers, fibrinogen), high sensitive C-reactive protein and ultrasound parameters of endothelial function (flow-mediated dilation-FMD, common carotid intima-media thickness-C-IMT, and antero-posterior diameter of infra-renal abdominal aorta-APAO) were assessed in 52 ALL survivors and 34 sex and age-matched controls...
