Comparison of Degree of Stenosis and Plaque Volume for the Assessment of Carotid Atherosclerosis Using 2-D Ultrasound

Correlation between Doppler Velocities and Duplex Ultrasound Carotid Cross-sectional Percent Stenosis

“…The relevance of RL was confirmed by a further analysis showing that RL was the most important regressor of ICA-EDV. The combined information given by ICA-EDV and RL seems therefore more important than ICA-PSV, plaque volume, and ICA-TA to allow a more careful estimation of the degree of stenosis and is in agreement with other authors (39). In fact, increased blood flow velocity is more correlated with RL than with plaque area.…”

Adaptation of the Main Peripheral Artery and Vein to Long Term Confinement (MARS 500)

“…Thus IMT increase is considered as a risk factor or a marker of aging at the vascular level like the increase in distal vascular resistance or hypertension. Nevertheless despite an increased IMT is considered as a risk factor associated with atheromatous lesion, no correlation was found between elevated IMT and presence of high degree of stenosis [18].…”

“…Patients with cardiovascular risk factors and increased IMT have a higher risk to have cardiovascular events than those with normal IMT [17], [18]. Thus IMT increase is considered as a risk factor or a marker of aging at the vascular level like the increase in distal vascular resistance or hypertension.…”

3D Quantitative Evaluation of Atherosclerotic Plaque Based on Rotational Angiography

“…2,[5][6][7][8] Advances in imaging technology have made it possible to observe the 3D geometric changes of blood vessels and evaluate the degree of vessel narrowing in patients by using techniques such as MR imaging and CT. 6,7,9,10 Researchers have also presented various techniques and computational models to assess irregular vascular geometry and to estimate the characteristics of atherosclerotic plaque. 5,7,[11][12][13] While plaque volume has been reported as an important tool for patient management and for evaluating new therapies, [14][15][16] methods to evaluate this index are limited. 14,15,17,18 Because conventional angiography remains the criterion standard for the diagnosis of vascular diseases, 19,20 techniques that can quantify plaque by using conventional angiography data can be useful.…”
