Carotid intima‐media thickness (IMT) may be measured by ultrasound, where the distance between a double‐line reflex pattern representing the luminal‐intimal and the . Intima-media thickness (IMT) is defined by the measurement of a component of the walls of muscular arteries (intima) by specific modalities of ultrasound, at defined locations in the human body. Intima-media thickness of the carotid artery has been the location most consistently associated with risk of atherosclerotic risk. In 2012, the Mannheim Carotid Intima-Media Thickness and Plaque Consensus published the last update guidelines for CIMT measurement . CIMT is observed as a double line pattern visualized between the intimal-luminal and the medial-adventitial interfaces of the carotid wall in a longitudinal view by B-mode ultrasound (Fig. 1 ).Radiopaedia.org
The carotid intima-media thickness test (CIMT) is a measure used to diagnose the extent of carotid atherosclerotic vascular disease. Carotid-wall intima–media thickness is a surrogate measure of atherosclerosis 1 associated with cardiovascular risk factors 2 and with cardiovascular outcomes. 3–7 The intima–media thickness . B-mode ultrasound measurements of the carotid intima-media thickness (CIMT) have been first described in 1986 by Pignoli et al. in an in vitro study of common carotid arteries. 2 The investigators showed that the distance between the lumen and intima interface of the common carotid artery from pathologic examination did not differ from distance .
Sonographic Intima Media Thickness measurement of the carotid artery (cIMT: carotid Intima-Media-Thickness) is considered a valid surrogate marker for cardiovascular risk allowing assessment of atherosclerotic changes at a very early stage. It is easy to apply due to its non-invasive character. Moreover, cIMT has been proven to provide reliable .
This review is an attempt to discuss the most performing methodologies that have been developed so far to perform computer-based segmentation and intima–media thickness (IMT) measurement of the carotid arteries in ultrasound images.First we will present the rationale and the clinical relevance of computer-based measurements in clinical practice, followed by .
An intravascular optical coherence tomography (IVOCT) method was developed to simultaneously measure the circumferentially distributed intima-media thickness, strain and strain rate of carotid artery with high accuracy in vivo.. An elastic modulus calculation method was proposed based on the cyclic strains for biomechanical properties characterization of the .
One of the first main advances in IMT measurement methodology was provided by the first international consensus on intima-media thickness and plaque organized during the 13th and updated on the 15th European Stroke Conference Mannheim Carotid Intima-Media Consensus (2004–2006) [].It was followed in 2008 by the consensus statement of the .
The intima-media thickness of the far wall of the right common carotid artery, just distal to the carotid artery bulb, was determined at end diastole. Carotid artery intima-media thickness was expressed as a mean (in millimeters) of 70 to 100 standardized measurements between the intima lumen and media adventitia interfaces over a 10-mm length. Carotid intima-media thickness (CIMT) is widely used in observational studies to determine determinants and consequences of atherosclerosis. 1–11 Several studies have shown that increased CIMT confers risk of future coronary heart disease and stroke, 12–18 although some indicated no increased risk. 19 In several studies CIMT was related to absolute risks of . In 2012, the Mannheim Carotid Intima-Media Thickness and Plaque Consensus published the last update guidelines for CIMT measurement . CIMT is observed as a double line pattern visualized between the intimal-luminal and the medial-adventitial interfaces of the carotid wall in a longitudinal view by B-mode ultrasound (Fig. 1 ).The carotid intima-media thickness test (CIMT) is a simple yet powerful tool for assessing heart health. This quick, painless procedure uses ultrasound to measure the thickness of the inner layers of the carotid artery walls.A CIMT test can help detect early signs of heart disease and stroke risk, allowing for timely intervention and prevention.
Multiple studies have shown that the carotid artery intima-media thickness (IMT), as measured noninvasively by ultrasonography, is directly associated with an increased risk of cardiovascular disease. Because it has been shown to be an independent predictor of cardiovascular disease after adjustment for traditional risk factors, it is the only noninvasive .
This is a video taken by Evan Matthews, PhD displaying the right common carotid artery and intima media thickness (IMT) measurement. Both the posterior (far). Cardiovascular diseases (CVDs) are the top ten leading causes of death worldwide. Atherosclerosis disease in the arteries is the main cause of the CVD, leading to myocardial infarction and stroke. The two primary image-based phenotypes used for monitoring the atherosclerosis burden is carotid intima-media thickness (cIMT) and plaque area (PA). .Epidemiological studies showed that the thickness of the major arteries is an early and effective marker of onset of cardiovascular diseases. . A state of the art review on intima-media thickness (IMT) measurement and wall segmentation techniques for carotid ultrasound Comput Methods Programs Biomed. 2010 Dec;100(3):201-21. doi: 10.1016/j .
The distance between the arrows from the lumen–intima interface to the media–adventitia interface indicates an intima–media thickness of 1.12 mm. Abbreviation: DICOM, Digital Imaging and .The two primary image-based phenotypes used for monitoring the atherosclerosis burden is carotid intima-media thickness (cIMT) and plaque area (PA). Earlier segmentation and measurement methods were based on ad hoc conventional and semi-automated digital imaging solutions, which are unreliable, tedious, slow, and not robust.
The measurement of Carotid Intima Media Thickness (IMT) on Common Carotid Artery (CCA) is a principle marker of risk of cardiovascular disease. This paper presents a novel method of using deep Convolutional Neural Network (CNN) for identification and measurement of IMT on the far wall of the artery. The Region of Interest (ROI) is extracted using CNN .
Mannheim Carotid Intima-Media Thickness and Plaque Consensus (2004–2006–2011): An Update on Behalf of the Advisory Board of the 3rd and 4th Watching the Risk Symposium 13th and 15th European Stroke Conferences, Mannheim, Germany, 2004, and Brussels, Belgium, 2006 . Ultrasound protocols to measure carotid intima-media thickness in trials .
Context The evidence that measurement of the common carotid intima-media thickness (CIMT) improves the risk scores in prediction of the absolute risk of cardiovascular events is inconsistent. Objective To determine whether common CIMT has added value in 10-year risk prediction of first-time myocardial infarctions or strokes, above that of the .
A third of deaths in the world are due to cardiovascular diseases [1]. Atherosclerosis is the major cause of myocardial infarction, which occurs by deposition of plaque in the coronary artery. The chance of stroke rises with the thickening of carotid artery due to the plaque. Hence, accurate measurement of the intima-media thickness is necessary for predicting the chance . The commercially available semi-automatic intima-media thickness measurement software Máth 3.2.0 (Intelligence in Medical Imaging, Paris, France) was used for CIMT measurements. The operator identified the area to measure: a continuous one-centimetre segment of the distal two centimetres in the CCA far wall.Figure 1. Measurement of CCA-IMT. Longitudinal ultrasound images of the common carotid artery are shown for a 57-year-old Caucasian woman with a Framingham Risk Score (FRS) of 1% and with normal carotid intima-media thickness (<25th percentile) (A), and for a 58-year-old Caucasian man with a history of familial hypercholesterolemia and an FRS of 8% (B).
A well‐used method of assessing atherosclerosis at the subclinical stage is the measurement of the thickness of the intimal and medial layers of the carotid artery wall, termed carotid intima‐media thickness (cIMT). 3 The value of cIMT in research has been widely used as a surrogate measure of the burden of carotid atherosclerosis 4 and a predictor of CVD for .
