Emergency Neuroradiology

A Case-Based Approach

Emergency Neuroradiology

Neuroradiological emergencies pose important challenges to the on-call physician, demanding thorough preparedness and quick action. This concise, highly illustrated volume covers all facets of emergency neuroradiology in a clear, easily searchable way, making it ideal both for effective learning and for rapid reference. Over 150 cases, accompanied by nearly 800 high-quality CT and MRI images, guide the reader through both common and uncommon presentations in all three key areas: brain, head and neck, and spine. Each case consists of a short history, images, diagnosis, differential diagnosis, key points in bullet form, and suggested readings. The cases are organized into thematic chapters to provide a structured approach for primary learning, but every case remains independent and fully searchable for guidance when on call. With its practically focused approach, this book is a must for radiology residents, fellows and practicing radiologists, and will also benefit specialists in neurology, neurosurgery and emergency medicine.

Emergency Neuroradiology

Emergency Neuroradiology

Encouraged by the success of the Italian editions, the Authors have decided to publish an English version taking into account the latest technical and methodological advances and the consequent new acquisitions in clinical practice. The contribution of Professor R. Jinkins has been essential to carry out both these tasks. The resulting work is an up-to-date technical tool that preserves its original aim of contributing to the training of those radiologists who work in emergency departments. We hope that this revised and extended English version will have the same success as the pre- ous Italian editions, thereby confirming the validity of our initiative. The work of all the friends and colleagues who have contributed to the making of this book is gratefully acknowledged. Tommaso Scarabino Ugo Salvolini CONTENTS I.

Problem Solving in Neuroradiology E-Book

Problem Solving in Neuroradiology E-Book

Problem Solving in Neuroradiology, by Meng Law, MD, Peter M. Som, MD and Thomas P. Naidich, MD, is your survival guide to solving diagnostic challenges that are particularly problematic in neuroimaging. With a concise, practical, and instructional approach, it helps you apply basic principles of problem solving to imaging of the head and interventional neck, brain, and spine. Inside, you'll find expert guidance on how to accurately read what you see, and how to perform critical techniques including biopsy, percutaneous drainage, and tumor ablation. User-friendly features, such as tables and boxes, tips, pitfalls, and rules of thumb, place today's best practices at your fingertips, including protocols for optimizing the most state-of-the-art imaging modalities. A full-color design, including more than 700 high-quality images, highlights critical elements to enhance your understanding. Apply expert tricks of the trade and protocols for optimizing the most state-of-the-art imaging modalities and their clinical applications used for the brain and spine—with general indications for use and special situations. Make the most efficient use of modern imaging modalities including multidetector CT, PET, advanced MR imaging/MR spectroscopy (MRS), diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), and perfusion weighted imaging (PWI). Successfully perform difficult interventional techniques such as biopsies of the spine and interventional angiography—key techniques for more accurately diagnosing cerebral vascular disease, aneurysm, and blood vessel malformations—as well as percutaneous drainage and tumor ablation. Know what to expect. A dedicated section is organized by the clinical scenarios most likely to be encountered in daily practice, such as neurodegenerative disease, vascular disease, and cancer. Avoid common problems that can lead to an incorrect diagnosis. Tables and boxes with tips, pitfalls, and other teaching points show you what to look for, while problem-solving advice helps you accurately identify what you see—especially those images that could suggest several possible diagnoses. See conditions as they appear in practice thanks to an abundance of case examples and specially designed full-color, high-quality images which complement the text and highlight important elements. Quickly find the information you need thanks to a well-organized, user-friendly format with templated headings, detailed illustrations, and at-a-glance tables.

Acute Ischemic Stroke

Imaging and Intervention

Acute Ischemic Stroke

This updated second edition of Acute Ischemic Stroke: Imaging and Intervention provides a comprehensive account of the state of the art in the diagnosis and treatment of acute ischemic stroke. The basic format of the first edition has been retained, with sections on fundamentals such as pathophysiology and causes, imaging techniques and interventions. However, each chapter has been revised to reflect the important recent progress in advanced neuroimaging and the use of interventional tools. In addition, a new chapter is included on the classification instruments for ischemic stroke and their use in predicting outcomes and therapeutic triage. All of the authors are internationally recognized experts and members of the interdisciplinary stroke team at the Massachusetts General Hospital and Harvard Medical School. The text is supported by numerous informative illustrations, and ease of reference is ensured through the inclusion of suitable tables. This book will serve as a unique source of up-to-date information for neurologists, emergency physicians, radiologists and other health care providers who care for the patient with acute ischemic stroke.
