Near-infrared spectroscopy (NIRS) combined with intravascular ultrasound (NIRS-IVUS) is a novel catheter-based intravascular imaging modality that provides a chemogram of the coronary artery wall, which enables the detection of lipid core and specific quantification of lipid accumulation Cited by: 1.

Intravascular imaging-intravascular ultrasound and more recently optical coherence tomography-provide a tomographical or cross-sectional image Intravascular ultrasound imaging in coronary artery disease book the coronary arteries. These techniques are clinically useful to answer questions such as whether the stenosis is clinically relevant; the identification of the culprit lesion; or whether the plaque Cited by: Intravascular ultrasound (IVUS) imaging is mostly used in the diagnosis and treatment of coronary artery diseases, especially in atherosclerosis, because it becomes very difficult to identify in.

Intravascular Ultrasound (IVUS) is a catheter-based diagnostic procedure used to view the inside of a coronary artery, providing a real-time view. IVUS shows the degree of narrowing or thickening (stenosis) of an artery by providing a visual image of the inside of the artery (the lumen) and the atheroma (membrane/cholesterol loaded white blood.

Intravascular Ultrasound Menu Overview Test Details An invasive procedure, performed along with cardiac catheterization; a miniature sound probe (transducer) on the tip of a coronary catheter is threaded through the coronary arteries and, using high-frequency sound waves, produces detailed images of the interior walls of the arteries.

Intravascular ultrasound (IVUS) represents the first clinical imaging technique enabling routine tomographic imaging of coronary arteries. Comprehensive technical and clinical reviews of IVUS have recently been publishedIn this article we will give a brief summary of IVUS techniques and then describe the role of tomographic coronary imaging Cited by: Intravascular ultrasound imaging has contributed to circumvent some limitations of coronary angiography by providing information on the characteristics of the arterial wall and facilitating accurate measurements of luminal dimensions.

In addition to providing valuable in vivo observations on the natural history of Intravascular ultrasound imaging in coronary artery disease book artery disease, it has contributed significantly Intravascular ultrasound imaging in coronary artery disease book the assessment of Author: Javier Escaned.

Intravascular Ultrasound (IVUS) This is one of many examples of interventional techniques pioneered by Stanford researchers. IVUS is an imaging technique that has become the international gold standard for detection and evaluation of coronary artery disease.

Intravascular ultrasound (IVUS) uses a transducer or probe to generate sound waves and produce images of blood vessels. When used to evaluate the coronary arteries, IVUS can show the entire artery wall and provide important information about the amount and type of plaque buildup, which can help determine if you are at risk for heart attack.

In contrast, greyscale intravascular ultrasound can fully assess the extension of the disease axially and longitudinally. This intravascular imaging technique has played a vital role in advancing our understanding of the pathophysiology of coronary artery disease,File Size: KB. Therefore direct imaging of the vessel wall has become a new goal in the assessment of CAD progression and prevention.

Intravascular ultrasound (IVUS) represents the first clinical imaging technique enabling routine tomographic imaging of coronary by: Introduction. Percutaneous coronary intervention (PCI) is a mainstay for the treatment of coronary artery disease, a major cause of morbidity and mortality worldwide.

1 Although coronary angiography (CA) is the standard imaging modality used for coronary stent implantation, it is limited to 2‐dimensional projections of coronary anatomical : Fahed Darmoch, M. Chadi Alraies, Yasser Al‐Khadra, Homam Moussa Pacha, Duane S. Pinto, Eric A. Osbor. Download Citation | Intravascular Ultrasound | In the half century since it was initially performed, coronary angiography has become the preferred imaging modality.

Frompatients underwent grayscale and RF-IVUS of a nonculprit, nonstenotic coronary artery while undergoing coronary angiography for stable angina or acute coronary syndrome (ACS).

IVUS findings were analyzed and compared among those with and without major adverse cardiac events (MACE) during follow-up. In contrast, greyscale intravascular ultrasound can fully assess the extension of the disease axially and longitudinally. This intravascular imaging technique has played a vital role in advancing our understanding of the pathophysiology of coronary artery disease, and in the development of novel cardiovascular drugs and device by:   Intravascular ultrasound (IVUS) and intravascular optical coherence tomography (IVOCT) are widely utilized clinical imaging modalities employed for the diagnosis and treatment of coronary artery and peripheral vascular by: 9.

We performed intravascular ultrasound imaging before or after, or both, various transcatheter therapies in patients. These 84 men and 26 women had a mean age of 60 years and a duration of angina of 22 ± 34 months.

Forty-nine patients had one-vessel, 29 had two-vessel, 25 had three-vessel and 7 had left main coronary disease. Detecting obstructive disease of the left main coronary artery (LMCA) disease is a relatively unusual occurrence in the catheterisation laboratory, as it accounts for approximately 4 % of all coronary angiograms, with isolated LMCA disease observed in only 5–10 % of these cases.

Methods: A retrospective study including 20 patients undergoing both coronary angiography and IVUS examinations of the left coronary artery was set up for the validation. The same vessel segments of interest between proximal and distal Cited by: Intravascular ultrasound (IVUS) can resolve abnormalities within the coronary artery to a degree that is not possible with angiography alone.

With an axial resolution of μm and lateral resolution of μm, IVUS can provide information on arterial wall and luminal composition that can change clinical management decisions. In vivo coronary imaging techniques became available more than years later with the introduction of selective coronary angiography in by Mason Sones.

Selective coronary angiography has allowed the identification of significantly stenotic. Detection of obstructive disease of the left main coronary artery (LMCA) is relatively unusual in the catheterisation laboratory, as it accounts for approximately 4 % of all coronary angiograms, with isolated LMCA disease observed in only 5–10 % of these cases.

1 Intervention to the LMCA is, however, notable compared to the treatment of coronary stenosis elsewhere in the coronary Author: Giovanni Luigi De Maria, Adrian P Banning. Intravascular ultrasound (IVUS) is an alternative technique to coronary angiography. It reveals the structure and composition of the vessel wall by means of a circumferential view.

IVUS application for diagnosis of coronary artery disease is a well explained method and its results in detecting allograft vasculopathy have been reported previously. Intravascular ultrasound (IVUS) has emerged from a research tool to an intrinsic part of modern invasive cardiology.

The main reason is the capability to obtain “in-vivo” histology. For the first time it is possible to base decisions not only on lumenograms but also on vessel wall by: 9.
