Book excerpt: Contrast enhanced ultrasound imaging provides a real-time tool for evaluating vasculature in the liver. Primary liver cancer is perfused primarily by blood from the hepatic artery, whereas normal liver is also supplied by the portal vein. Visual separation of two different phases of enhancement is a challenge. This thesis presents a method of using factor analysis of high dimensional data as a method of extracting distinct time-intensity curves. Key components to this extraction are the clustering of measured bolus curves and their projection onto a positivity domain to obtain non-negative curves. This technique provides complementary images representing spatial loadings on each curve. A method of combining this information to display a regional hepatic perfusion image is proposed, and results are tested on a small set of patients. Region of interest analysis suggests it is possible to detect changes in the hepatic perfusion index of liver lesions relative to normal liver parenchyma using contrast ultrasound.

This book was released on 2021-06-26 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide reader an overview of clinical applications of contrast-enhanced ultrasound in hepatic neoplasms diagnosis. Ultrasound images and pathological results of different hepatic neoplasms are introduced in the chapters, including benign liver tumors, malignant liver tumors, hepatic carcinoma, intrahepatic cholangiocarcinoma, rare liver benign and malignant neoplasms, regenerative nodules, inflammatory pseudotumor, parasite liver lesions, and hepatitis peliosis, etc. The combination of ultrasound findings with final histopathological results then discover the potential mechanical of contrast enhancement changes. With the development of ultrasound technology and widely application of ultrasound contrast agents (USCA) in recent decades, contrast-specific imaging modalities have been developed in combination with USCA and a low mechanical index (MI), allowing continuous real-time grey scale imaging. The updated contrast-specific software for liver diseases and hepatic tumors diagnosis has also been described described in detail. With high-resolution contrast ultrasound images during arterial phase, portal venous phase and late phase, author wants to show the whole dynamic wash-in and wash-out process of the different focal liver lesions.This book is an invaluable resource for radiologists, hepatologists and oncologists in their everyday clinical practice.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents up-to-date information on clinical and research applications of imaging in peripheral arterial disease (PAD). It provides high-quality images useful not only in the diagnosis of PAD but also for use in clinical trials aimed at the development of novel therapies such as angiogenic agents and stem cells. The book begins with coverage of the applications of the four major imaging modalities in a clinical setting: ultrasound, computed tomography angiography (CTA), magnetic resonance angiography (MRA), and digital subtraction angiography (DSA). It also discusses the ankle brachial index (ABI) as a screening technique to establish the presence of PAD. Subsequent chapters focus on the advantages and limitations of various research applications of imaging in PAD including contrast ultrasound for measuring perfusion; MRI for assessing perfusion, energetics, plaque volume, and characteristics; and radionuclide imaging for perfusion and inflammation. Imaging in Peripheral Arterial Disease: Clinical and Research Applications is an essential resource for physicians, researchers, residents, and fellows in cardiology, radiology, imaging, nuclear medicine, diagnostic radiology, and vascular surgery.

This book was released on 2012-12-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, the development of sonographic contrast agents - or "microbubbles" - has stimulated increasingly intensive studies on the rela tionships between ultrasound and contrast media. As a result, "contrast -spe cific" hardware and software systems have been introduced by different ultra sound manufacturers with impressive speed. This has finally led to the birth of a very new imaging modality -"contrast-enhanced sonography" (CEUS). Since 1999, the introduction of second-generation contrast agents has represented a decisive step towards the extensive clinical use of CEUS and has simultaneously made obsolete most, if not all, scientific publications available so far. This book is, to our knowledge, the first to deal entirely with second generation contrast agents and the most updated contrast-specific software for noncardiologic uses. The reasons why the liver has been chosen as the only "target" of the book are easily understandable by radiologists and hepatologists alike. The study of vascularity is the only purpose of CEUS, and the liver has a unique vascular system, with two different inflow systems resulting in a single outflow. Furthermore, the pathologically different focal liver lesions (FLLs) are mostly characterized by different "models" of vascularity: CEUS can mimic contrast enhanced computed tomography and magnetic resonance imaging, basing differential diagnosis on the morphological and temporal characteristics of enhancement, but with the additional unique advantage of the study being done in real-time.

This book was released on 2005-01-12 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The value of ultrasound contrast agents (USCA) in everyday clinical practice depends on the pharmacokinetics, the signal processing, and the contrast-specific imaging modalities. Second-generation USCA, are blood pool agents that do not leak into the organ tissue to be examined but remain in the intravascular compartment increasing the Doppler signal amplitude during their dynamic vascular phase. Taking advantage of the stability of their microbubbles, they can withstand the acoustic pressure of insonation much better than first-generation contrast media, which results in an increased half-life of the agent and, consequently, in a prolonged diagnostic window. Concomitant with the improvement of contrast agents, different contrast-specific imaging modalities have been developed which, used in combination with USCA and a low mechanical index, allow continuous real-time grey-scale imaging. These recent technical improvements have opened new possibilities in the use of USCA in a variety of indications. Written by internationally renowned experts, the contributions gathered in this book give an overview of current and possible future new applications of USCA in routine and clinical practice.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the technology required for the successful application of contrast echo cardiography has evolved rapidly over the past few years, the technique has not yet gained widespread clinical acceptance. One important reason for the lack of clinical acceptance is the relative complexity of the technique, particularly in respect to myocardial perfusion imaging. The interaction between micro bubbles and ultrasound is an entire field by itsel£ as is the coronary microvasculature. It is in this regard that practicing echocardiographers, cardiologists in training, radiologists, so no graphers, and students will find 'A Handbook of Contrast Echocardiography' particularly useful. Written by two leaders in the field who have presented illustrative cases not only from their own laboratories but also from others around the world, this volume is a lucid, concise, and practical guide for the day-to-day use of contrast echocardiography. Dr Peter Burns has been involved in almost all the technical advances in the imaging methods that have made it possible to detect opacification of the left ventricular cavity and myocardium from a venous injection of microbubbles. He has been responsible to a large degree for advancing our understanding of the interaction between micro bubbles and ultrasound, which he describes in clear and easy to understand terms in this book. Dr Harald Becher has been active in the clincal application of contrast echocardiography for several years and has gained considerable experience with many imaging techniques and microbubbles, which he describes in this volume in some detail.
