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.

Download or read book MRI from Picture to Proton written by Donald W. McRobbie and published by Cambridge University Press. This book was released on 2017-04-13 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.

Book excerpt: Magnetic Resonance Imaging (MRI) is a non-invasive modality for neuroimaging that has been widely applied into various clinical and scientific studies. In many applications, one particular challenge for MRI is the scanning speed and efficiency. Three major novel fast neuroimaging techniques are presented in this work, including high-resolution 3D diffusion imaging (3D-SNAILS), an iterative reconstruction algorithm for high accelerating parallel imaging (PRUNO), and motion insensitive 3D non-contrast perfusion imaging (3D-PCASL-PROMO). 3D DWI and DTI provide attractive features such as isotropic resolution, high SNR and good tractography. However, 3D volumetric DWI/DTI scans suffer from long scan time and severe motion artifacts. In this project, a steady-state multi-shot pulse sequence is demonstrated to perform fast high resolution 3D diffusion imaging, in which 3D self-navigated interleaved rotating spirals (3D-SNAILS) are used as readout trajectories. This acquisition scheme has low sensitivity to motion induced phase errors and the inherent navigators can be utilized to further reduce motion artifacts. In vivo human/animal results have shown that this technique can be used to perform 3D high resolution DTI studies, particularly for animals with smaller brains. GRAPPA has been a successful k-space data-driven reconstruction algorithm for parallel imaging during the last decade. However, the performance of GRAPPA drops significantly as the accelerating factor increases. A novel iterative method termed parallel reconstruction using null operations (PRUNO) is developed in this project. In this approach, both data calibration and image reconstruction are formulated into generalized linear system equations based on intrinsic small k-space nulling kernels. And a conjugate-gradient (CG) method is proposed to solve the reconstruction equation feasibly. With more accurate problem formulation and higher calibration efficiency, PRUNO produces much better image quality than GRAPPA, especially under high accelerating factors. Pulsed continuous arterial spin labeling (PCASL) is a novel technique for 3D whole-brain perfusion imaging. However, a whole brain clinical PCASL protocol takes long imaging time due to multiple image acquisitions and averages. A real-time motion correction algorithm is thus desired for such a protocol. Prospective motion correction (PROMO) is a navigator based module, which can be easily inserted into various MR pulse sequences for real-time 3D motion estimation and correction. PROMO is successfully integrated into PCASL in this project. Our preliminary results show that the new pulse sequence is much more robust against patient motions and PROMO navigators have almost no negative influence to the imaging sequence. In addition, brief abstracts of two other fast imaging projects are also demonstrated in this dissertation, including a fast T2* imaging pulse sequence called iESGRE, and 7T diffusion imaging of rats using SNAILS.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview of recent developments in magnetic particle imaging (MPI), a novel imaging modality. Using various static and oscillating magnetic fields, and tracer materials made from iron oxide nanoparticles, MPI can perform background-free measurements of the particles’ local concentration. The method exploits the nonlinear remagnetization behavior of the particles and has the potential to surpass current methods for the detection of iron oxide in terms of sensitivity and spatiotemporal resolution. Starting from an introduction to the technology, the topics addressed include setting up an imaging device, assessment of image quality, development of new MPI tracer materials, and the first preclinical results. This is the first book to be published on magnetic particle imaging, and it will be an invaluable source of information for everyone with an interest in this exciting new modality.

Available in PDF, EPUB and Kindle. Book excerpt: MRI Atlas of Human White Matter presents an atlas to the human brain on the basis of T 1-weighted imaging and diffusion tensor imaging. A general background on magnetic resonance imaging is provided, as well as the basics of diffusion tensor imaging. An overview of the principles and limitations in using this methodology in fiber tracking is included. This book describes the core white-matter structures, as well as the superficial white matter, the deep gray matter, and the cortex.

Download or read book MRI of the Lung written by Hans-Ulrich Kauczor and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade significant developments have been achieved in the field of magnetic resonance imaging (MRI), enabling MRI to enter the clinical arena of chest imaging. Standard protocols can now be implemented on up-to-date scanners, allowing MRI to be used as a first-line imaging modality for various lung diseases, including cystic fibrosis, pulmonary hypertension and even lung cancer. The diagnostic benefits stem from the ability of MRI to visualize changes in lung structure while simultaneously imaging different aspects of lung function, such as perfusion, respiratory motion, ventilation and gas exchange. On this basis, novel quantitative surrogates for lung function can be obtained. This book provides a comprehensive overview of how to use MRI for imaging of lung disease. Special emphasis is placed on benign diseases requiring regular monitoring, given that it is patients with these diseases who derive the greatest benefit from the avoidance of ionizing radiation.
