An interdisciplinary guide to vascular color flow imaging and CEUS organized by anatomic region The indications for vascular color duplex sonography (CDS) have expanded in recent years due to the availability of power Doppler, B-flow, ultrasound contrast agents, 3D reconstruction techniques, and fusion with other imaging modalities. CDS enables close-interval follow-ups after interventional procedures with improved prognoses. Edited by Reinhard Kubale, Hubert Stiegler, and Hans-Peter Weskott, Vascular Ultrasound: B-Mode, Color Doppler and Duplex Ultrasound, Contrast-Enhanced Ultrasound starts with the basic principles of diagnostic ultrasound physics and technology, followed by invaluable tips on equipment settings, possible artifacts, and limitations; hemodynamic essentials; and the use of ultrasound contrast agents. Subsequent chapters organized by anatomic region provide coverage of all peripheral and abdominal arterial and venous vascular regions; microcirculation and tumor perfusion; kidney and liver diseases; vascular malformations; non-atherosclerotic vascular diseases; the use of contrast-enhanced ultrasound (CEUS) in biliary, intestinal, splenic, and pediatric diseases; and novel/future techniques. Key Features Contributions from interdisciplinary experts in angiology, neurology, radiology, vascular surgery, gastroenterology, nephrology, phlebology, rheumatology, laser medicine, and physics In-depth guidance on examination techniques, findings, and potential pitfalls and how to avoid them A wealth of comparative CT, MRI, and angiography CDS images and 37 videos enhance the understanding of impacted anatomy and the ability to master techniques and make accurate diagnoses.
