This book explores the basic scientific principles, theory, and techniques associated with peripheral vascular ultrasound and blood flow. It clearly explains how to interpret color images and Doppler spectra, as well as how to optimize scanner controls for the most effective results. Chapters include descriptions of vascular disorders, carotid duplex ultrasound, lower and upper limb arterial and venous assessment, ultrasound assessment of aneurysms, graft surveillance and pre-operative vein marking, and more. Clinical chapters also contain current criteria for grading disease. The latest technological advances, such as harmonic imaging and compound imaging, are integrated with an emphasis on safety. * Practical, step-by-step guidance on scanning shows how to perform specific procedures. * Discussions of ultrasound physics are directly tied to applications for scanning and assessing blood flow. * High-quality line drawings and images show how to perform the scan and what practitioners can expect to see. * Basic scientific principles of ultrasound instrumentation and blood flow are discussed. * Limitations and pitfalls of techniques are presented.
