This book was released on 2024-07-12 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The acquisition of resting cerebral perfusion measures using magnetic resonance imaging (MRI) is one of the assessments of cerebrovascular health used to discern how well patients are coping with anatomical changes such as stenosis, and other factors impacting the supply of blood flow to the brain. Perfusion measures may be obtained using several MRI based techniques including arterial spin labeling (ASL) and dynamic contrast enhanced methods that rely on injected contrast agents such as gadolinium. Recently hypoxia-induced changes in deoxyhemoglobin have been used as a non-invasive contrast agent, measuring the resulting changes in blood oxygen dependent (BOLD) signals with MRI. With each approach, the means through which voxel-wise cerebral perfusion information is derived differs, leading to the development a variety of analysis methods in recent studies. This Research Topic is intended to attract manuscripts that advance the use of resting cerebral perfusion measures in clinical assessments of cerebrovascular health. In pursuit of this aim a better understanding of several aspects are needed.

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advances in Neurochemistry series was initiated for a readership of neuroscientists with a background in biochemistry. True to this concept, the present volume brings together various applications of magnetic resonance technology to advance our knowledge of how the nervous system functions. Whether at the cellular, tissue slice, or intact organism level. magnetic resonance techniques are by their nature noninvasive, and thus provide a window through which biochemical reactions can be viewed without grinding, binding, or other wise perturbing ongoing physiological processes. As technological improve ments in methodology, such as higher and more uniform magnetic fields, novel paradigms for data analysis, etc. , are made, we find increased sensitivity and improved temporal and spatial resolution for functional imaging techniques on the one hand, and better separation of signals that identify chemical properties in spectral shift studies, on the other. It is upon knowledge such as is described in the twelve chapters that follow, that further advances in scientific discovery and the biomedical applications of tomorrow will be based. We are grateful to Dr. Bachelard, the Volume Editor, and to the authors of the individual chapters for their efforts. We also note that with this volume Dr. Morris Aprison, a co-founder of the Advances in Neurochemistry series has stepped down and acknowledge with thanks his major role in its inception. In addition, we thank our past and present Advisory Editors. Bernard W.

Available in PDF, EPUB and Kindle. Book excerpt: This book will familiarize the reader with the basic principles of perfusion MR imaging. Relevant technical aspects, contrast agents, and the postprocessing of images are presented, and imaging protocols are provided. Dedicated software for personal use on the postprocessing of images is provided on a CD-ROM containing hundreds of images and movie clips that demonstrate all concepts. In addition to the technical details of acquisition and postprocessing, numerous examples of the application of these tools in the clinical setting are also shown. In particular, the book includes a discussion of the role of perfusion MRI in the current evaluation of cerebrovascular disease, including an integrative approach using diffusion in conjunction with perfusion imaging. This text covers: all relevant technical aspects of perfusion MR imaging imaging protocols application of these tools in a clinical setting integration of diffusion imaging with perfusion imaging for enhanced diagnostic capabilities Also addressed are the role of perfusion MRI in the assessment of cerebral neoplasia, challenges and opportunities for treatment that tumors present, and the particular strengths of perfusion MRI, such as its relatively high resolution and possible microvascular specificity. For both newcomers and experienced practitioners, this is a nuts-and-bolts description of an important new technique.

Book excerpt: ​Vascular management and care has become a truly multidisciplinary enterprise as the number of specialists involved in the treatment of patients with vascular diseases has steadily increased. While in the past, treatments were delivered by individual specialists, in the twenty-first century a team approach is without doubt the most effective strategy. In order to promote professional excellence in this dynamic and rapidly evolving field, a shared knowledge base and interdisciplinary standards need to be established. Pan Vascular Medicine, 2nd edition has been designed to offer such an interdisciplinary platform, providing vascular specialists with state-of-the art descriptive and procedural knowledge. Basic science, diagnostics, and therapy are all comprehensively covered. In a series of succinct, clearly written chapters, renowned specialists introduce and comment on the current international guidelines and present up-to-date reviews of all aspects of vascular care.

Download or read book Cerebral Blood Flow written by Andrea Boicelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on "Cerebral Blood Flow: Mathematical Models, Instrumentation, and Imaging Techniques" was held in L'Aquila, Italy, June 2-13, 1986. Contributions to this program were received from the University of L'Aquila, Consiglio Nazionale delle Ricerche, Siemens Elettra S.p.A., and Bracco S.p.A. Recent studies of the cerebral blood circulation have lagged behind analysis of other parameters such as glucose utilization, transmitter distribution, and precursors. This Advanced Study Institute tried to fill this gap by analyzing in detail different physical techniques such as Autoradiography (including Double-Tracer Auto radiography and highly specific tracers as Iodoantipyrine, Micro spheres), Single Photon Emission Computed Tomography, Nuclear Magnetic Resonance. Each method was analyzed in regards to its precision, resolution, response time. A considerable part of this Institute was devoted to the mathematics of CBF measurement, in its two aspects, i.e. the modeling of the underlying kinetic system and the statistical analysis of the data. The modeling methods proposed included the development of a differential algebra whereby the differential and integral equations involved could be solved by simple algebraic methods, including graph theoretical ones; the statistical methods proposed included the illustration of different parametrizations of possible use in the interpretation of experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: Building on the success of the first edition of this book, the winner of the 2004 British Medical Association Radiology Medical Book Competition, Quantitative MRI of the Brain: Principles of Physical Measurement gives a unique view on how to use an MRI machine in a new way. Used as a scientific instrument it can make measurements of a myriad of physical and biological quantities in the human brain and body. For each small tissue voxel, non-invasive information monitors how tissue changes with disease and responds to treatment. The book opens with a detailed exposition of the principles of good practice in quantification, including fundamental concepts, quality assurance, MR data collection and analysis and improved study statistical power through minimised instrumental variation. There follow chapters on 14 specific groups of quantities: proton density, T1, T2, T2*, diffusion, advanced diffusion, magnetisation transfer, CEST, 1H and multi-nuclear spectroscopy, DCE-MRI, quantitative fMRI, arterial spin-labelling and image analysis, and finally a chapter on the future of quantification. The physical principles behind each quantity are stated, followed by its biological significance. Practical techniques for measurement are given, along with pitfalls and examples of clinical applications. This second edition of this indispensable 'how to' manual of quantitative MR shows the MRI physicist and research clinician how to implement these techniques on an MRI scanner to understand more about the biological processes in the patient and physiological changes in healthy controls. Although focussed on the brain, most techniques are applicable to characterising tissue in the whole body. This book is essential reading for anyone who wants to use the gamut of modern quantitative MRI methods to measure the effects of disease, its progression, and its response to treatment. Features: The first edition was awarded the book prize for Radiology by the British Medical Association in 2004 Written by an authority in the field: Professor Tofts has an international reputation for quantification in MRI Gives specific ‘how to’ information for implementation of MRI measurement sequence techniques
