The brilliant yet simple idea of introducing a catheter percutaneously into an artery, without first dissecting it free, using a flexible guide wire, has led to a truly revolutionary breakthrough in abdominal x-ray diag nosis (SELDINGER, 1953). In the meantime, methods and techniques for injecting contrast media into various vessels have become largely standardized; innumerable publications have appeared which deal with every conceivable aspect of angiographic technique and interpretation. This volume is designed to present our experience with abdominal angiography. We deliberately refrained from any systematic discussion of the genitourinary tract, which has been adequately dealt with in the literature, also with respect to angiographic findings. Our interest in the retroperitoneal region is based mainly on its significance in differential diagnosis. In ten years of angiographic activity, our Department had made successful use of a simple technique which appears suitable also for smaller hospitals. We wish to point out its diagnostic potential and, at the same time, to outline its limitations. Our experience embraces 2804 abdominal angiograms, which we have classified according to clinical and morphologic anatomical criteria. Their diagnostic interpretation has been compared with the surgical or histopathological results. This may help others to avoid errors of the type which we discovered in our own work. Angiographic diagnosis requires not only familiarity with normal radiographic anatomy, but also specific knowledge of angiographic patho morphology. We have tried to identify those features which typify the individual findings and to derive therefrom valid generalizations with the aid of simple sketches.

This atlas presents normal and pathologic findings observed on CT angiography with 3D reconstruction in a diverse range of clinical applications, including the imaging of cerebral, carotid, thoracic, coronary, abdominal and peripheral vessels. The superb illustrations display the excellent anatomic detail obtained with CT angiography and depict the precise location of affected structures and lesion severity. Careful comparisons between normal imaging features and pathologic appearances will assist the reader in image interpretation and treatment planning and the described cases include some very rare pathologies. In addition, the technical principles of the modality are clearly explained and guidance provided on imaging protocols. This atlas will be of value both to those in training and to more experienced practitioners within not only radiology but also cardiovascular surgery, neurosurgery, cardiology and neurology.

This book is a highly visual guide to the radiographic and advanced imaging modalities - such as computed tomography and ultrasonography - that are frequently used by physicians during the treatment of emergency patients. Covering practices ranging from ultrasound at the point of care to the interpretation of CT scan results, this book contains over 2,200 images, each with detailed captions and line-art that highlight key findings. Within each section, particular attention is devoted to practical tricks of the trade and tips for avoiding common pitfalls. Overall, this book is a useful source for experienced clinicians, residents, mid-level providers, or medical students who want to maximize the diagnostic accuracy of each modality without losing valuable time.

With an abundance of illustrations and tables to highlight critical information, this source provides a practical approach to the use of CO2 as a contrast agent for diagnostic angiography, vascular intervention, and other interventional procedures in both adults and pediatrics. Clearly laying-out key points in the science, technique, and clinical a

This text discusses the basic aspects of multislice CT angiography with chapters on technical principles, basic scan technique for peripheral vascular imaging with multislice CT, image reconstruction with multislice CT, radiation doses, and contrast agent administration. Clinical applications for each major vascular territory are covered in-depth,

This open access book focuses on diagnostic and interventional imaging of the chest, breast, heart, and vessels. It consists of a remarkable collection of contributions authored by internationally respected experts, featuring the most recent diagnostic developments and technological advances with a highly didactical approach. The chapters are disease-oriented and cover all the relevant imaging modalities, including standard radiography, CT, nuclear medicine with PET, ultrasound and magnetic resonance imaging, as well as imaging-guided interventions. As such, it presents a comprehensive review of current knowledge on imaging of the heart and chest, as well as thoracic interventions and a selection of "hot topics". The book is intended for radiologists, however, it is also of interest to clinicians in oncology, cardiology, and pulmonology.

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.
