Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. . Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel size and plaque characteristi
Carotid ultrasound is a low-cost, noninvasive, and accurate diagnostic imaging modality used to evaluate diseases of the carotid arteries. [2] It is most often used to diagnose carotid artery stenosis, a form of atherosclerosis, and has the capability to assess plaque morphology and characteristics. [1]
Intravascular ultrasound provides a unique method to study the regression or progression of atherosclerotic lesions in vivo. [2] The progressive accumulation of plaque within the artery wall over decades leads to the development of unstable vulnerable plaque which can detach as clots
An ultrasound to measure blood flow. ... Metformin to help control plaque for people with diabetes. Nitrates to reduce chest pain from angina. Ranolazine for coronary microvascular disease.
“Plaque buildup, or atherosclerosis, is the process that leads to blockages of the coronary arteries that supply the heart muscle. This is also called coronary artery disease.
Examples of anatomical detection methods include coronary calcium scoring by CT, carotid IMT (intimal media thickness) measurement by ultrasound, and intravascular imaging techniques, such as intravascular ultrasound (IVUS), and intravascular optical coherence tomography (OCT), [85] [86] allowing direct visualization of atherosclerotic plaques.
Ultrasound measurements of carotid IMT were first proposed and validated in vitro by Paolo Pignoli in 1984 [2] and further details were subsequently published in a highly cited article. [3] The use of IMT as a non-invasive tool to track changes in arterial walls has increased substantially since the mid-1990s. [1]
[75] [88] Plaque and blood flow can be evaluated using ultrasound, CT angiography, MR angiography, and catheter-based angiography to establish anatomic segments of disease. The severity of ischemia can be evaluated by correlating symptoms and non-invasive physiologic vascular studies including toe pressures, TCPO2, and skin perfusion studies.
