Mri Physics For Radiologists

When this book was initially published three years ago, it was my goal to delineate the principles of magnetic resonance imaging in a format that could be understood without a sophisticated physics or mathematics back ground. That is still my goal. However, in the interim, it has become clear to me that many magnetic resonance techniques that we now routinely use are inadequately understood by many of us. Therefore, I have re-structured and expanded the book in the following way. There are now three main sections: of the sections one and two deal with the contrast and spatial characteristics image, as they did in the original text; and an additional section deals with various peripheral but significant magnetic resonance topics. Sections one and two still provide the "meat" of the material through the guise of the spin-echo pulse sequence; but section three goes beyond by explaining other pulse cycles and devices that are commonly used in today's imaging centers. To begin with, since fast scanning has now become a widely used tech nique, that chapter has been significantly expanded, and now includes a complete but non-mathematical explanation of what a gradient echo is and how fast scan images differ in principle from spin-echo images. Also, the applications of 3DFT and "half-Fourier" imaging are graphically covered without mathematical intervention.

MRI Physics for Radiologsits: A Visual Approach, Third Edition delineates the principles of magnetic resonance imaging in a format that can be understood by readers who do not have a sophisticated physics or mathematics background. It is organized in three sections: sections one and two present the contrast and spatial characteristics of the image; section three deals with topics such as Half Fourier imaging, motion, aliasing, artifacts, and coils. The third edition has sections on new techniques now in common use, such as rectangular field of view and fast spin-echo (or echo-planar) sequences, a chapter on the effect of MR equipment parameters on image resolution, a chapter with a simplified mathematical discussion of the Fourier transform and an enhanced section on magnetic resonance angiography.

Since the first edition was published in 1993, MRI in Practice has become the standard text for radiographers, technologists, radiology residents, radiologists and even sales representatives on the subject of Magnetic Resonance Imaging (MRI). This text is essential reading on undergraduate and postgraduate MRI courses. Furthermore MRI in Practice has come to be known as the number one reference book and study guide in the areas of MR instrumentation, principles, pulse sequences, image acquisition, and imaging parameters for the advanced level examination for MRI offered by the American Registry for Radiologic Technologists (ARRT) in the USA. The book explains in clear terms the theory that underpins magnetic resonance so that the capabilities and operation of MRI systems can be fully appreciated and maximised. This fourth edition captures recent advances, and coverage includes: parallel imaging techniques and new sequences such as balanced gradient echo. Building on the success of the first three editions, the fourth edition has been fully revised and updated. The book now comes with a companion website at www.wiley.com/go/mriinpractice which hosts animated versions of a selection of illustrations in the book that are used on the MRI in Practice Course. These animations and accompanying text are aimed at helping the reader’s comprehension of some of the more difficult concepts. The website also hosts over 200 interactive self-assessment exercises to help the reader test their understanding. MRI in Practice features: Full color illustrations Logical presentation of the theory and applications of MRI A new page design A companion website at www.wiley.com/go/mriinpractice featuring interactive multiple choice questions, short answer questions PLUS animations of more complex concepts from the book For more information on the MRI in Practice Course and other learning resources by Westbrook and Talbot, please visit www.mrieducation.com

In MRI Physics for Physicians the author presents the physical principles of magnetic resonance imaging without detailing the more sophisticated mathematics and physics typically used by physicists when explaining such phenomena. This book is mainly intended for radiologists and clinical physicians who are interested in learning the basic principles of how and why magnetic resonance imaging works but do not want to become excessively involved with the mathematics. It is divided into two parts: the first covers the general aspects of magnetic resonance and the resulting signals while the second explains how the magnetic resonance signals form the three-dimensional images. Explanations of all relevant physical and mathematical terms and concepts, including basic vector and field theory and the more complicated principles of wave theory and Fourier transform mathematics, are given in an easily understood, straightforward, yet thorough, manner.

Over recent years there has been a vast expansion in the variety of imaging techniques available, and developments in machine specifications continue apace. If radiologists and radiographers are to obtain optimal image quality while minimising exposure times, a good understanding of the fundamentals of the radiological science underpinning diagnostic imaging is essential. The second edition of this well-received textbook continues to cover all technical aspects of diagnostic radiology, and remains an ideal companion during examination preparation and beyond. The content includes a review of basic science aspects of imaging, followed by a detailed explanation of radiological sciences, conventional x-ray image formation and other imaging techniques. The enormous technical advances in computed tomography, including multislice acquisition and 3D image reconstruction, digital imaging in the form of image plate and direct radiography, magnetic resonance imaging, colour flow imaging in ultrasound and positron radiopharmaceuticals in nuclear medicine, are all considered here. A chapter devoted to computers in radiology considers advances in radiology information systems and computer applications in image storage and communication systems. The text concludes with a series of general topics relating to diagnostic imaging. The content has been revised and updated throughout to ensure it remains in line with the Fellowship of the Royal College of Radiologists (FRCR) examination, while European and American perspectives on technology, guidelines and regulations ensure international relevance.
