Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Ultrasound assessment of carotid disease is currently based on stenosis haemodynamic effects. The accuracy of direct stenosis measurement remains unclear, while research on atherosclerosis suggests identification of other plaque characteristics beyond size. The aim of the study is to investigate whether direct stenosis measurement and plaque ultrasound image analysis could potentially be used for more accurate diagnostic investigation. Method and material: Eighty-seven patients with cardiovascular disease had a carotid duplex ultrasound scan and velocity and B-mode measurements data were recorded for direct diameter measurement evaluation. Forty patients were scanned for quantitative plaque analysis and association of several parameters with symptoms was investigated. Results: For the degree of stenosis, ECST method indicated greater agreement among direct measurement methods with velocity criteria, however in cases of mild stenosis difference was reported. ECST method measurements showed considerably better agreement with MRA stenosis calculations compared with other methods. Intima- media grey scale level was associated with plaque echogenicity but the correlation was not significant, however there was an association with blood cholesterol levels. Percentages of plaque area with grey scale value less than 35 and 40 showed good accuracy in identifying symptomatic patients. As far as fibrous cap is concerned, a thickness less than 300 urn was well correlated with symptomatic disease, however no association was noted for its echogenicity. Conclusion: ECST direct stenosis measurement method could potentially be used for better stenosis classification in cases with inconclusive haemodynamic estimations. Quantitative plaque analysis, such as fibrous cap thickness measurement and grey level analysis, shows promising results in association with symptomatic disease and particular plaque characteristics.

Download or read book Multi Modality Atherosclerosis Imaging and Diagnosis written by Luca Saba and published by Springer Science & Business Media. This book was released on 2013-09-13 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stroke is one of the leading causes of death in the world, resulting mostly from the sudden ruptures of atherosclerosis carotid plaques. Understanding why and how plaque develops and ruptures requires a multi-disciplinary approach such as radiology, biomedical engineering, medical physics, software engineering, hardware engineering, pathological and histological imaging. Multi-Modality Atherosclerosis Imaging, Diagnosis and Treatment presents a new dimension of understanding Atherosclerosis in 2D and 3D. This book presents work on plaque stress analysis in order to provide a general framework of computational modeling with atherosclerosis plaques. New algorithms based on 3D and 4D Ultrasound are presented to assess the atherosclerotic disease as well as very recent advances in plaque multimodality image fusion analysis. The goal of Multi-Modality Atherosclerosis Imaging, Diagnosis and Treatment is to fuse information obtained from different 3D medical image modalities, such as 3D US, CT and MRI, providing the medical doctor with some sort of augmented reality information about the atherosclerotic plaque in order to improve the accuracy of the diagnosis. Analysis of the plaque dynamics along the cardiac cycle is also a valuable indicator for plaque instability assessment and therefore for risk stratification. 4D Ultrasound, a sequence of 3D reconstructions of the region of interest along the time, can be used for this dynamic analysis. Multimodality Image Fusion is a very appealing approach because it puts together the best characteristics of each modality, such as, the high temporal resolution of US and the high spatial resolutions of MRI and CT.

Download or read book Ex vivo Three dimensional Assessment of Carotid Stenosis with Ultrasound written by Kathie Lynn Dionisio and published by . This book was released on 2005 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atherosclerosis causes heterogeneous remodeling of arterial structure and composition in the carotid vessel wall. It has been shown that the progression of the disease can be monitored by tracking changes in the carotid intima-media thickness (IMT). Non-invasive peripheral vascular ultrasound (U/S) of the carotid artery is a non-invasive, cost effective, accepted means of measuring IMT. Traditionally, evaluation of IMT in the carotid has been limited to 2D U/S scans. This method is disadvantageous as 2D scans are scan plane dependent, limiting the area over which one can evaluate the extent of the disease. Reproducing the identical scan plane on subsequent scans is also difficult. Evaluation of the carotid vessel wall in 3D will allow for a more complete and reproducible assessment of disease through IMT measurements. We have constructed a fully 3D image processing scheme for analyzing carotid U/S volumes to extract the inner and outer vessel wall boundaries. Sequences of 2D B-mode U/S cross sections of ex-vivo carotid specimens are collected and voxelized to create 3D U/S volumes. By applying a 3D directionally sensitive, edge preserving filter to the U/S volumes, we obtain 3D edge fields that are more distinct than traditional gradient edge fields. Initial point selection of the boundaries, together with these enhanced 3D edge fields, are used with a deformable surface to extract the final inner and outer vessel boundaries. Through intra- and inter-observer tests on IMT differences, we show that the 3D boundaries extracted using our automatic technique are more reproducible than boundaries extracted from manual point selection.
