The role of calcification in coronary artery disease is gaining importance, both in research studies and in clinical application. Calcified plaque has long been considered to be the most important atherosclerotic plaque within the arterial tree and frequently presents a challenge for percutaneous intervention. Current investigations have shown that plaque calcification has a dynamic course that...

Abstract Introduction Peyronie’s disease (PD) is characterized by penile pain, deformation and curvature, sexual dysfunction, psychological implications. Fibrosis plaque formation are often part of PD pathophysiology. Calcified plaques can alter treatment planning. Penile ultrasound with Doppler (PUS) used to exclude erectile dysfunction identify plaques. However, extent distribution be obscure...

Modern techniques in dental research continue to assist in the study of the mode of (anticaries) action of topical fluorides. The Plaque Glycolysis and Regrowth Model (PGRM) facilitates the standardized assessments of antimicrobial effects on plaque following use of test formulations in vivo without complications arising from coincident mineral reactivity. In vivo plaque glycolysis testing demo...

BACKGROUND AND PURPOSE Automatically identifying carotid plaque composition using MR imaging remains a challenging task in vivo. The purpose of our study was to compare the detection and quantification of carotid artery atherosclerotic plaque components based on in vivo MR imaging data using manual and automated segmentation. MATERIALS AND METHODS Sixty patients from a multicenter study were ...

Oral disease an on-going concern During the last century, there has been a world-wide surge of interest in veterinary dentistry. Interstitial gingivitis or so-called pyorrhoea alveolaris” was reported in dogs as far back as 1899. In 1939 the prevalence of dental disease and requirement for surgical intervention in dogs was also reported. Dental disease is certainly not a new “modern” problem in...

PURPOSE OF REVIEW Atherosclerotic plaque rupture and subsequent acute events, such as myocardial infarction and stroke, contribute to the majority of cardiovascular-related deaths. Calcification has emerged as a significant predictor of cardiovascular morbidity and mortality, challenging previously held notions that calcifications stabilize atherosclerotic plaques. In this review, we address th...

The purpose of this study was to characterize cardiovascular tissue components and analyze the different tissue properties for predicting coronary vulnerable plaque from intravascular ultrasound (IVUS) images. For this purpose, sequential IVUS image frames were obtained from human coronary arteries using 20 MHz catheters. The plaque regions between the intima and media-adventitial borders were ...

BACKGROUND High-speed rotational atherectomy uses a diamond-coated, elliptical burr to abrade occlusive atherosclerosis, especially noncompliant calcified plaque. METHODS AND RESULTS Intravascular ultrasound (IVUS) was used to analyze 28 patients after atherectomy. Arteries treated and imaged were left main (three), left anterior descending (12), left circumflex (five), right coronary (seven)...

BACKGROUND Material decomposition of dual-energy computed tomography (DECT) enables subtraction of calcified plaque. PURPOSE To evaluate the accuracy of lumen area measurement in calcified plaque by subtraction of DECT and to determine the effect of contrast material concentration, lumen diameter, density, and thickness of calcified plaque for the measurement. MATERIAL AND METHODS Vessel ph...
