Fundamentals of Body MRI—a new title in the Fundamentals of Radiology series—explains and defines key concepts in body MRI so you can confidently make radiologic diagnoses. Dr. Christopher G. Roth presents comprehensive guidance on body imaging—from the liver to the female pelvis—and discusses how physics, techniques, hardware, and artifacts affect results. This detailed and heavily illustrated reference will help you effectively master the complexities of interpreting findings from this imaging modality. Master MRI techniques for the entirety of body imaging, including liver, breast, male and female pelvis, and cardiovascular MRI. Avoid artifacts thanks to extensive discussions of considerations such as physics and parameter tradeoffs. Grasp visual nuances through numerous images and correlating anatomic illustrations.
This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
This issue reviews the latest advances in MR angiography. Angiography of the thoracic, abdominal, renal, and peripheral blood vessels is reviewed in this issue. Also included are articles on angiography of atherosclerotic plaque, functional techniques, and new contrast agents.
The first book to cover the groundbreaking development and clinical applications of Magnetic Resonance Elastography, this book is essential for all practitioners interested in this revolutionary diagnostic modality. The book is divided into three sections. The first covers the history of MRE. The second covers technique and clinical applications of MRE in the liver with respect to fibrosis, liver masses, and other diseases. Case descriptions are presented to give the reader a hands-on approach. The final section presents the techniques, sequence and preliminary results of applications in other areas of the body including muscle, brain, lung, heart, and breast.
In recent years, there has been increasing interest in the clinical applications of coronary angiography techniques. Coronary MRA can be instrumental in the evaluation of congenital coronary artery anomalies, however, the complexity of advanced MR pulse sequences and strategies may be overwhelming to many. Coronary MR Angiography demystifies the art of coronary MRA by providing a text in plain language with clearly illustrated imaging steps and protocols. Designed to bridge the gap between radiology and cardiology, it is written for physicians and scientists planning to incorporate this technique into their research or practice.
Magnetic resonance angiograhy (MRA) is a new non-invasive imaging procedure to directly view the vasculature. This text presents a practical review of this technique, its indications and the role it plays for the general radiologist and specialist, neurologist, cardiologist and vascular surgeon, in the diagnosis of vascular disorders.
Quantitative Magnetic Resonance Imaging is a 'go-to' reference for methods and applications of quantitative magnetic resonance imaging, with specific sections on Relaxometry, Perfusion, and Diffusion. Each section will start with an explanation of the basic techniques for mapping the tissue property in question, including a description of the challenges that arise when using these basic approaches. For properties which can be measured in multiple ways, each of these basic methods will be described in separate chapters. Following the basics, a chapter in each section presents more advanced and recently proposed techniques for quantitative tissue property mapping, with a concluding chapter on clinical applications. The reader will learn: - The basic physics behind tissue property mapping - How to implement basic pulse sequences for the quantitative measurement of tissue properties - The strengths and limitations to the basic and more rapid methods for mapping the magnetic relaxation properties T1, T2, and T2* - The pros and cons for different approaches to mapping perfusion - The methods of Diffusion-weighted imaging and how this approach can be used to generate diffusion tensor - maps and more complex representations of diffusion - How flow, magneto-electric tissue property, fat fraction, exchange, elastography, and temperature mapping are performed - How fast imaging approaches including parallel imaging, compressed sensing, and Magnetic Resonance - Fingerprinting can be used to accelerate or improve tissue property mapping schemes - How tissue property mapping is used clinically in different organs - Structured to cater for MRI researchers and graduate students with a wide variety of backgrounds - Explains basic methods for quantitatively measuring tissue properties with MRI - including T1, T2, perfusion, diffusion, fat and iron fraction, elastography, flow, susceptibility - enabling the implementation of pulse sequences to perform measurements - Shows the limitations of the techniques and explains the challenges to the clinical adoption of these traditional methods, presenting the latest research in rapid quantitative imaging which has the possibility to tackle these challenges - Each section contains a chapter explaining the basics of novel ideas for quantitative mapping, such as compressed sensing and Magnetic Resonance Fingerprinting-based approaches
This book is intended as a text/reference for students, researchers, and professors interested in physical and biomedical applications of Magnetic Resonance Imaging (MRI). Both the theoretical and practical aspects of MRI are emphasized. The book begins with a comprehensive discussion of the Nuclear Magnetic Resonance (NMR) phenomenon based on quantum mechanics and the classical theory of electromagnetism. The first three chapters of this book provide the foundation needed to understand the basic characteristics of MR images, e.g.,image contrast, spatial resolution, signal-to-noise ratio, common image artifacts. Then MRI applications are considered in the following five chapters. Both the theoretical and practical aspects of MRI are emphasized. The book ends with a discussion of instrumentation and the principles of signal detection in MRI. - Clear progression from fundamental physical principles of NMR to MRI and its applications - Extensive discussion of image acquisition and reconstruction of MRI - Discussion of different mechanisms of MR image contrast - Mathematical derivation of the signal-to-noise dependence on basic MR imaging parameters as well as field strength - In-depth consideration of artifacts in MR images - Comprehensive discussion of several techniques used for rapid MR imaging including rapid gradient-echo imaging, echo-planar imaging, fast spin-echo imaging and spiral imaging - Qualitative discussion combined with mathematical description of MR techniques for imaging flow
Practical Body MRI: Protocols, Applications and Image Interpretation demystifies MRI examinations of the abdomen and pelvis, giving the essential knowledge required by radiologists in order to develop and select appropriate protocols, assess scan quality and interpret imaging studies. Each chapter describes why each sequence is performed, what to look for, and how the important findings from each sequence lead to a unique diagnosis. Numerous protocols are included, from the more common, such as liver and renal MRI, to more tailored examinations such as rectal and placental MRI. All protocols are richly illustrated with images of body MR pathology. A separate chapter discusses MRA/MRV and an introductory chapter gives a brief, practical introduction to MRI physics and receiver coils. The authors' expertise and practical, concise explanations of both protocols and image interpretation makes this an essential resource for residents, fellows and experienced radiologists using body MRI for the first time.
