Book Description
Non-invasive, high resolution contrast arteriography without arte rial catheterization or nephrotoxicity is now possible. It is accomplished by using paramagnetic contrast and an MR scanner. Paramagnetic contrast media is injected intravenously and image data are collected as the con trast circulates through the vascular territory of interest. Due to the strong enhancement effect of paramagnetic contrast media, a small dose injected as an intravenous bolus is sufficient to briefly enhance the entire arterial vascular tree. This allows imaging with a large field-of-view that encompasses an extensive region of vascular anatomy. By using a 3D gradient echo pulse sequence on magnets with high performance gra dient systems, high resolution 3D volumes of image data are acquired in a single breath-hold. This has vastly improved image quality of 3D con trast MRA exams, particularly in the chest and abdomen. Subsequent post-processing allows an angiographic display of image data in any desired obliquity. The success of this technique is reflected by its incorporation into clinical practice in centers throughout the world. It has been applied to multiple vascular territories, using various magnets, and slightly differ ing imaging strategies. As is the ca se for all MR imaging techniques, a thorough understanding of the underlying mechanisms and proper technique are essential to fully exploit the diagnostic potential of this new form of angiography. This book will familiarize the reader with the basic principles of 3D contrast MRA.

Book Description
The first book-length reference to thoroughly describe diagnostic and therapeutic advances in the development of vascular radiology over the last decade The last ten years has seen vascular imaging of the central nervous system (CNS) evolve from fairly crude, invasive procedures to more advanced imaging methods that are safer, faster, and more precise—with computed tomographic (CT) and magnetic resonance (MR) imaging methods playing a special role in these advances. Vascular Imaging of the Central Nervous System is the first full-length reference text that shows radiologists—especially neuroradiologists—how to optimize the use of the many techniques available in order to increase the sensitivity and specificity of vascular imaging, thereby improving the diagnosis and treatment of individual patients. Each chapter is formatted carefully and divided into two essential parts: The first part describes the physical principles underlying each imaging technique, along potential associated artifacts and pitfalls; the second part addresses clinical applications and novel applications of each method. With a strong focus on the clinical application of each modality or technique in CNS radiology, this book provides in-depth chapter coverage of: • Ultrasound Vascular Imaging (UVI) • Computed Tomography Angiography (CTA) • Magnetic Resonance Vascular imaging (MRV) • Digital subtraction angiography (DSA) • Brain perfusion techniques: CT and MRI • Plaque imaging • Intravascular imaging • Pediatric vascular imaging Along with numerous illustrations and case studies, Vascular Imaging of the Central Nervous System: Physical Principles, Clinical Applications, and Emerging Techniques is an important book for those faced with choosing from the wide range of choices available for clinical practice.

Book Description
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.

Book Description
The advent of contrast-enhanced MRA in the early to mid 1990s revolutionized the clinical approach to vascular imaging: an accurate non-invasive imaging modality, not requiring ionizing radiation or potentially nephrotoxic iodinated contrast media, was able to compete with the more hazardous and invasive catheter angiography. Today, MRA is a safe, easy-to-perform procedure routinely used in most imaging centers, and the continued development of faster, more powerful magnets and more effective contrast agents is increasingly helping to overcome many of the early limitations of the technique. Subdivided into three sections (technique, indications and practical applications) and written by internationally renowned experts in the field, this volume stands out in the current literature on MRA by providing: - detailed information on sequence parameters for different magnets and vascular territories for the optimization of the MRA technique; - a broad overview of the principal indications for which contrast-enhanced MR angiography is ideally suited; - the typical MR imaging findings associated with various pathologies; - the appropriateness of contrast-enhanced MRA as compared with other modalities, such as CTA and CEUS; - the potential pitfalls and limitations of the technique in clinical routine. The volume will prove invaluable to radiologists and clinicians wishing to expand, improve, or consolidate their routine approach to vascular MR imaging.

Book Description
Conventional coronary angiography can lead to infections, injuries to the arteries, and in rare cases, heart attack or death. Using the new, rapidly developing technique of contrast-enhanced angiography (CEA), also known as magnetic resonance angiography (MRA), cardiologists can now quickly and effectively evaluate a broad range of vascular abnormalities, including the kinds of problems often seen with traditional echocardiography. An Atlas of Contrast-Enhanced Angiography uses images taken directly from the magnetic resonance scanner to illustrate the application of CEA to all the common pathologies and anomalies seen in the cardiovascular system. It contains tables, charts, and line diagrams that delineate the angiograms. Authors Mohiaddin and Bunce supply explanatory text supporting and complementing the figures and providing clinical diagnoses and investigations of a multitude of normal and abnormal findings. A clinical aid to diagnosis and a review text containing bibliographic references and index, An Atlas of Contrast-Enhanced Angiography allows you to learn from the current leaders in the field. In addition, it provides you with a visual aide to the diagnosis and management of vascular disease.
