Magnetic Resonance Imaging In Ischemic Stroke

Provides a comprehensive summary of the current role of MR imaging in patients with ischemic stroke. Specifically designed to meet the needs of both clinicians and radiologists. Documents the MR correlates of specific stroke syndromes. Contains many high-quality illustrations.

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 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.

An essential companion for busy professionals seeking to navigate stroke-related clinical situations successfully and make quick informed treatment decisions.

Advances in magnetic resonance imaging (MRI) are transforming the investigation and treatment of cerebrovascular disease. Echoplanar techniques with diffusion and perfusion weighted imaging, together with developments in magnetic resonance spectroscopy and angiography, are replacing CT scanning as the diagnostic modality of choice. In this profusely illustrated book world leaders in these technologies review the scientific basis and clinical applications of MRI in stroke. It will appeal to a broad readership including stroke physicians, neurologists, neurosurgeons, rehabilitation specialists, and others with a clinical or research interest in cerebrovascular disease.

Stroke MRI is a new imaging tool providing detailed information of the pathophysiological aspects of cerebral ischemia. This book - with CD-ROM - includes a case collection of 25 hyperacute stroke patients, all imaged within six hours of stroke onset with a complete stroke MRI protocol. Stroke MRI and the established clinical methods are compared and recent results from single and multicenter trials are presented to demonstrate the advantages of MRI for stroke patients. The CD-ROM contains diffusion-, T2-, T2*-perfusion-weighted images and MR angiography. The CD and the book are complementary to avoid redundancy as far as possible.

One in six suffers a stroke during their lifetime and stroke remains the major cause of new onset disability in adulthood. The worldwide burden of stroke is increasing due to an ageing population, however, globally haft of stroke victims are young. Stroke is the clinical diagnosis of an acute vascular incident and covers a multitude of pathophysiological causes. The clinician needs imaging to make decisions on acute treatment as well as to plan a secondary prevention strategy: a non-contrast CT and a Duplex of the carotids followed by an aspirin as a one size fits all strategy does not always provide sufficient support for those decisions. Presently, fast, generally available, and non-invasive imaging provides new possibilities of establishing a cause of stroke, provide specific information on the brain parenchyma – including possibly salvageable tissue and micro-bleeds – as well as allowing for more specific prognostication in acute stroke. This eBook covers both ischemic and haemorrhagic stroke and includes hot topics such as micro-bleeds, salvageable tissue and spot-sign, clinically challenging issues including movement artefacts in MRI as well as an overview of present options including pragmatic and feasible suggestions for an approach to state of the art acute imaging.

This open access book offers an essential overview of brain, head and neck, and spine imaging. Over the last few years, there have been considerable advances in this area, driven by both clinical and technological developments. Written by leading international experts and teachers, the chapters are disease-oriented and cover all relevant imaging modalities, with a focus on magnetic resonance imaging and computed tomography. The book also includes a synopsis of pediatric imaging. IDKD books are rewritten (not merely updated) every four years, which means they offer a comprehensive review of the state-of-the-art in imaging. The book is clearly structured and features learning objectives, abstracts, subheadings, tables and take-home points, supported by design elements to help readers navigate the text. It will particularly appeal to general radiologists, radiology residents, and interventional radiologists who want to update their diagnostic expertise, as well as clinicians from other specialties who are interested in imaging for their patient care.
