Download or read book Magnetic Resonance Brain Imaging written by Jörg Polzehl and published by Springer Nature. This book was released on 2019-09-25 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the modeling and analysis of magnetic resonance imaging (MRI) data acquired from the human brain. The data processing pipelines described rely on R. The book is intended for readers from two communities: Statisticians who are interested in neuroimaging and looking for an introduction to the acquired data and typical scientific problems in the field; and neuroimaging students wanting to learn about the statistical modeling and analysis of MRI data. Offering a practical introduction to the field, the book focuses on those problems in data analysis for which implementations within R are available. It also includes fully worked examples and as such serves as a tutorial on MRI analysis with R, from which the readers can derive their own data processing scripts. The book starts with a short introduction to MRI and then examines the process of reading and writing common neuroimaging data formats to and from the R session. The main chapters cover three common MR imaging modalities and their data modeling and analysis problems: functional MRI, diffusion MRI, and Multi-Parameter Mapping. The book concludes with extended appendices providing details of the non-parametric statistics used and the resources for R and MRI data.The book also addresses the issues of reproducibility and topics like data organization and description, as well as open data and open science. It relies solely on a dynamic report generation with knitr and uses neuroimaging data publicly available in data repositories. The PDF was created executing the R code in the chunks and then running LaTeX, which means that almost all figures, numbers, and results were generated while producing the PDF from the sources.

Download or read book Measurement of Magnetic Susceptibility in Brain Cortical Tissue by Magnetic Resonance Imaging written by Jorge Campos Pazmino and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Quantitative susceptibility mapping (QSM) is an MRI modality that can estimate the magnetic susceptibility distribution of tissue. QSM uses the assumption that phase shifts in the complex MR measured data are primarily produced by susceptibility-induced field perturbations within the volume-of-interest. Thus, QSM calculates the susceptibility distribution by solving the inverse problem of deriving the susceptibility distribution from the field perturbation in the phase data, which is an ill-posed inverse problem. To solve the inverse problem, the measured phase data requires first post-processing (phase offset correction, phase unwrapping, and weighted least square fit to combine multi-echo phase information) and the removal of background magnetic field perturbations (field perturbations produced outside the volume-of-interest). The separation of QSM in three steps corresponds to conventional QSM. The approach adopted in conventional QSM tends to break down in regions surrounded by steep changes of susceptibility, like the cortical region of the brain. Direct inversion methods combine the background removal and dipole inversion steps in a single algorithm and are proposed as a solution for the shortcomings of conventional QSM. The hypothesis of this project is thus that direct inversion methods are a better option to measure the susceptibility in the cortex when compared to conventional QSM. The results of this project indicate that among the studied methods, conventional QSM is a better option for measuring the susceptibility in deep grey matter structures, while direct inversion techniques are a promising approach to measure the susceptibility in the cortex of the brain. But the lack of refinement of these methods when solving the ill-posed inverse problem highlights the need to improve current methods or to develop novel techniques based on this approach. Also, it is proposed in this thesis that direct inversion methods rely on the orthogonality between the subspaces spanned by dipolar fields inside and outside the volume-of-interest. This theoretical framework explains why direct inversion methods are a promising technique to measure susceptibility in the cortex. Moreover, the proposed explanation outlines the path to improve direct inversion techniques"--
Download or read book Investigation of Multicomponent MRI Relaxation Data with Stochastic Contraction Fitting Algorithm written by Mary Elizabeth Russell and published by . This book was released on 2014 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain tissue can be identified and studied with Magnetic Resonance Imaging. Instead of relying only on the image, more advanced methods obtain quantitative measurements that describe specific tissues. Differential equations govern the shape of the magnetization curve, and the six unknown parameters of these equations are fit to the curves obtained from real data. The six parameter fit is performed numerically using a stochastic contraction algorithm. The stability of the results depend on the size of the original search space as well as additional factors. Numerical simulations were performed using this method and the results are concurrent with other literature results.

This book was released on 1996-03-13 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging. Incorporating input from dozens of biomedical researchers who described what they perceived as key open problems of imaging that are amenable to attack by mathematical scientists and physicists, this book introduces the frontiers of biomedical imaging, especially the imaging of dynamic physiological functions, to the educated nonspecialist. Ten imaging modalities are covered, from the well-established (e.g., CAT scanning, MRI) to the more speculative (e.g., electrical and magnetic source imaging). For each modality, mathematics and physics research challenges are identified and a short list of suggested reading offered. Two additional chapters offer visions of the next generation of surgical and interventional techniques and of image processing. A final chapter provides an overview of mathematical issues that cut across the various modalities.

Download or read book Quantitative MRI of the Spinal Cord written by Julien Cohen-Adad and published by Academic Press. This book was released on 2014-01-16 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative MRI of the Spinal Cord is the first book focused on quantitative MRI techniques with specific application to the human spinal cord. This work includes coverage of diffusion-weighted imaging, magnetization transfer imaging, relaxometry, functional MRI, and spectroscopy. Although these methods have been successfully used in the brain for the past 20 years, their application in the spinal cord remains problematic due to important acquisition challenges (such as small cross-sectional size, motion, and susceptibility artifacts). To date, there is no consensus on how to apply these techniques; this book reviews and synthesizes state-of-the-art methods so users can successfully apply them to the spinal cord. Quantitative MRI of the Spinal Cord introduces the theory behind each quantitative technique, reviews each theory’s applications in the human spinal cord and describes its pros and cons, and suggests a simple protocol for applying each quantitative technique to the spinal cord. Chapters authored by international experts in the field of MRI of the spinal cord Contains “cooking recipes —examples of imaging parameters for each quantitative technique—designed to aid researchers and clinicians in using them in practice Ideal for clinical settings
