BACKGROUND Coronary artery calcification which is determined quantitatively by coronary calcium scoring has been known as a sign of coronary stenosis and thus future cardiac events; hence it has been noticed on spotlight of researchers in recent years. Developing different method for early and optimal detection of coronary artery disease (CAD) is really essential as CAD are the first cause of d...

BACKGROUND Common carotid artery and internal carotid artery intima-media thicknesses (IMT) are associated with coronary heart disease (CHD) and increase with age. Using age, sex, and race/ethnicity IMT percentiles may improve CHD prediction when added to Framingham risk factors and coronary artery calcium score. We study these possibilities in the Multi-Ethnic Study of Atherosclerosis (MESA), ...

BACKGROUND Coronary artery disease (CAD) is the major cause of death among chronic renal failure (CRF) patients. Traditional, non-invasive exams to detect CAD and to predict events have shown insufficient results in this group. CT Scan evaluation of Coronary Calcium Score (CCS) has proven to be of prognostic value for the population reporting no renal condition. OBJECTIVE To investigate CCS a...

False-negative results of coronary artery calcium score (CACS) are common due to small calcified lesions being missed using a 3-mm slice thickness, a threshold of 130 Hounsfield units (HU) and a minimum area of 1 mm(2) for defining a calcified plaque. In contrast, false-positive results of CACS, as verified by a lack of coronary artery calcifications in computed tomography coronary angiogram (C...

OBJECTIVE To determine the agreement and reliability of fully automated coronary artery calcium (CAC) scoring in a lung cancer screening population. MATERIALS AND METHODS 1793 low-dose chest CT scans were analyzed (non-contrast-enhanced, non-gated). To establish the reference standard for CAC, first automated calcium scoring was performed using a preliminary version of a method employing coro...

OBJECTIVE To describe the distribution of coronary artery calcium scores in a population of asymptomatic white Brazilian men undergoing assessment with ultrafast computed tomography. METHODS The study assessed 2.253 men aged 22 to 88 years undergoing computed tomography in an Imatron C150 device for detecting coronary calcium. Data were divided based on the patient's age into 7 groups: < 40 y...

Background: Coronary calcium shows the atherosclerosis burden in coronary arteries and is associated with adverse cardiac events. Agatston score most widely used scoring sys-tem to quantify artery calcium. In this study, we aimed establish factors change time. Materials Methods: Patients who underwent multiple computerized tomo-graphic angiographies had measurements were included study. The of ...
