Download or read book Improving Assessments of Hemodynamics and Vascular Disease written by Magnus Ziegler and published by Linköping University Electronic Press. This book was released on 2019-04-24 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. This feedback loop is driven in part by the hemodynamic forces generated by the blood flow, and the distribution and strength of these forces appear to play a role in the initiation, progression, severity, and the outcome of vascular diseases. Magnetic Resonance Imaging (MRI) offers a unique platform for investigating both the form and function of the vascular system. The form of the vascular system can be examined using MR-based angiography, to generate detailed geometric analyses, or through quantitative techniques for measuring the composition of the vessel wall and atherosclerotic plaques. To complement these analyses, 4D Flow MRI can be used to quantify the functional aspect of the vascular system, by generating a full time-resolved three-dimensional velocity field that represents the blood flow. This thesis aims to develop and evaluate new methods for assessing vascular disease using novel hemodynamic markers generated from 4D Flow MRI and quantitative MRI data towards the larger goal of a more comprehensive non-invasive examination oriented towards vascular disease. In Paper I, we developed and evaluated techniques to quantify flow stasis in abdominal aortic aneurysms to measure this under-explored aspect of aneurysmal hemodynamics. In Paper II, the distribution and intensity of turbulence in the aorta was quantified in both younger and older men to understand how aging changes this aspect of hemodynamics. A method to quantify the stresses generated by turbulence that act on the vessel wall was developed and evaluated using simulated flow data in Paper III, and in Paper V this method was utilized to examine the wall stresses of the carotid artery. The hemodynamics of vascular disease cannot be uncoupled from the anatomical changes the vessel wall undergoes, and therefore Paper IV developed and evaluated a semi-automatic method for quantifying several aspects of vessel wall composition. These developments, taken together, help generate more valuable information from imaging data, and can be pooled together with other methods to form a more comprehensive non-invasive examination for vascular disease.

Download or read book Vascular Dynamics written by N. Westerhof and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The function of the vascular system is to transport oxygen and nutrients to the cells and to remove carbon dioxide and metabolites. It also transports hormones and locally produced neurohumoral substances which, in part, regulate its own function. These interrelationships are essential to homeostasis. The vascular system is not an assembly of simple (elastic) tubes but a dynamic system with many external and intrinsic regulatory mechanisms. The endothelium plays a major role in the intrinsic regulation of the system. The system is also often subject to disease processes of which atherosclerosis is the most important. As a result of atherosclerosis, and other disease processes, replacement of vessels with prosthetic devices may be required to reestablish adequate tissue blood flow. It is therefore imperative to gain insight into the details of vascular function, especially the dynamics, and the endothelium, the processes of atherosclerosis development, the vascular prosthetic possibilities and, last but not least, the interrelationships between these sub-specialties.
Download or read book Snapshots of Hemodynamics written by Nicolaas Westerhof and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written in a quick reference style to help clinical and basic researchers, as well as graduate students, in the understanding of hemodynamics. Recent dev- opments in genetics and molecular biology on the one hand, and new noninvasive measurement techniques on the other hand, make it possible to measure and und- stand the hemodynamics of heart and vessels better than ever before. Hemodynamics makes it possible to characterize, in a quantitative way, and even with noninvasive techniques the function of the heart and the arterial system, separately and in c- bination, thereby producing information about what genetic and molecular processes are of importance for cardiovascular function. We have made the layout of the book such that it gives a succinct overview of individual topics in short chapters Therefore every chapter starts with a “box” c- taining a figure and caption, describing the main aspects of the subject. It is often sufficient to study the contents of this box alone to obtain this basic information, and therefore it is not necessary to read the book from cover to cover.
Download or read book Microvascular Mechanics written by Jen-Shih Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: . . . we do not know a truth without knowing its cause. Aristotle Perhaps the greatest hope that may be entertained for a scientific work, whether experimental or theoretical, is that it leads to new thoughts and new avenues of investigation on the part of its readers. In microvascular mechanics, the interplay of rheology, anatomy, and cellular and organ function has only just begun to be addressed. To understand the operational behavior of microcirculation, there is a need to integrate studies at the cellular or molecu lar level with a quantitative, biomechanical description of the circulatory system. The symposium entitled "Frontiers in Cardiopulmonary Mechanics" held in June 1988 at the University of Virginia was intended to provide a fundamental approach to the description of the circulation from the per spective of microvascular mechanics and to examine new methodology that may advance this effort. This book arose out ofthe work presented at the symposium. Aristotle expressed well the need to pursue the causes of a phenomenon in order to achieve a truthful understanding of its nature. In this spirit has each of the quantitative sciences progressed, and in this spirit we hope that this book will provide some understanding of the microvascular events and bio mechanical mechanisms underlying the behavior of circulation in general, and of pulmonary and skeletal muscle microcirculation in particular. The integrated treatment of pulmonary and systemic microcirculation provided here is intended to encourage the cross-fertilization of these two research fields.
