Download or read book Int r t des syst mes particulaires en imagerie m dicale written by Cécile Graün and published by . This book was released on 2005 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'utilisation des systèmes particulaires pour la conception de produits de contraste présente de nombreux avantages. Non seulement ces systèmes contribuent à l'obtention du contraste mais surtout ils permettent un meilleur ciblage des produits de contraste augmentant ainsi leur sensibilité et leur spécificité. Ce ciblage peut être passif, par utilisation de la distribution naturelle des particules, ou actif, par greffage de ligands spécifiques de la cible à visualiser. Le ciblage actif est le plus prometteur car il est le plus spécifique. L'échographie est une technique simple, peu coûteuse et facilement accessible. Disposer d'un produit de contraste échographique qui permette le ciblage actif serait donc intéressant. Du fait de leur capacité à être greffées, nous avons souhaité préparer un tel produit à base de particules de PLGA. Le travail présenté ici montre qu'il est possible de préparer des particules de PLGA échogènes adaptées à l'administration intraveineuse.

Available in PDF, EPUB and Kindle. Book excerpt: Journalists, always very direct and in search of sensation, essentially asked me two questions on the occasion of this workshop: What were the goals of the meeting? With the improvement of diagnosis through the development of image techniques, didn't the contrast media already have their future behind them? Many answers were provided during the course of the workshop, and in order to best answer the journalists I proposed the following synopsis. 1. Since the 1979 Colorado Springs workshop organized by E. Lasser, progress has been so rapid and the newly available works so numerous that another meeting on an international level for the purpose of pre senting and discussing these advances appeared indispensable. Why not then in Europe and why not in Lyon? To expand on this progress, by 1981 the new contrast media with less-hyperosmolar molecules, still in the trial stage in 1979, were al most all available commercially for angiography, albeit at prohibitive prices. The advantages of these various media are becoming better known; moreover, in the wake of Lasser's work, our understanding of the pathophysiology of their noxious effects is also advancing rapidly owing to the use of models (for the target organs: heart, vessel wall, nervous system, kidney; and for the more general reactions: blood cells, coagulation, complement system, circulating enzymatic systems). In addition, further new molecules are currently being studied in re search laboratories. 2.

Available in PDF, EPUB and Kindle. Book excerpt: Recent advancements in nano/micro materials and related characterization approaches allow the design of a new type of ultrasound contrast agents (UCAs) with enhanced multifunctional behaviour. This is chance is also supported by the recent achievements in modelling and signal processing. This book provides the state of art of the research activity of two successful European projects, TAMIRUT and SIGHT, addressing an integrated system, encompassing the contrast agent, the hardware equipment and the processing strategies, as a key tool for a combined diagnostic and therapeutic approaches (theranostics) in medical ultrasound. The work provides a highlight of the state of art in the research of novel ultrasound contrast agents (UCAs). Main progresses on the multifunctional aspects of next-generation UCAs concern targeting and drug release properties, perfusion and biointerface behaviour, ultrasound scattering performance, signal processing, electronic equipment.
Download or read book Advances in X Ray Contrast written by P. Dawson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all that new non-X-ray technologies such as MR and ultrasound and its various manifestations have made an enormous impact in recent years on the practice of medical imaging, the use of X-rays and X-ray contrast-enhancing agents has retained an important position at the heart of the process. Indeed, with its frequent requirements for high total dose regimes, CT has increased the use of contrast agents. Even helical/spiral CT which, it was initially argued, should reduce contrast as well as radiation loads, may actually require just as much or more of both because of the potential it offers for multi-phase scanning. Iodinated intravascular X-ray contrast agents, especially the more recently developed non-ionic agents, continue therefore to play a pivotal role in clinical imaging. These succinct and authoritative articles, originally appearing in the journal Advances in X-ray Contrast, range sufficiently widely for their compilation in this volume to be considered a mini-textbook on the water-soluble iodinated X-ray contrast agents and their applications. Each is written by an acknowledged and experienced expert in the field. They usefully cover the developmental history of the agents; defined risk factors, approaches to prophylaxis and, ultimately, of the treatment of adverse reactions; the interesting subject of supposed delayed reactions to contrast agents; the important organ-specific toxicities, cardiac toxicity, neurotoxicity and nephrotoxicity and high-dose toxicity as encountered in complex procedures; the sometimes special circumstances and occasional extreme conditions to which contrast agents may be exposed in Interventional Radiology; the special, in several ways, case of paediatric radiology; the controversial subject of thromboembolic phenomena in clinical angiography; and the precise role of contrast agents. As regards the practicalities of contrast administration regimes and imaging protocols it is really only in the area of CT that there is debate and controversy, and articles are included which cover CT of the liver, spleen and pancreas, and protocols for the new spiral/helical technology and even for the much less widely available electron-beam CT technology visualization. Pulmonary embolus diagnosis and protocols for contrast administration with this technology are also discussed.

Download or read book Acoustic Characterization of Contrast Agents for Medical Ultrasound Imaging written by L. Hoff and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contrast agents for medical ultrasound imaging is a field of growing interest. A large amount of literature has been published on the medical applications of such contrast agents. However, there is no textbook giving a broad overview of the physics and acoustics of the agents. This monograph aims to fill this gap. The book is written by a physicist, from a physics point of view, and it tries to draw links from the physics and acoustics to the medical imaging methods, but medical applications are mainly included for background information. The book consists of nine chapters. The first three chapters give a broad overview of the acoustic theory for bubble-sound interaction, both linear and nonlinear. Most contrast agents are stabilized in a shell, and this shell can have a strong influence on the interaction between the bubbles and the ultrasound. The effect of the shell is given special attention, as this is not easily found in other bubble literature. The following chapters, 4, 5, 6, and 7, describe experimental and theoretical methods used to characterize the acoustic properties of the agents, and results of studies on some agents. Chapter 8 shows how the theory and the experimental results can be combined and used to model various phenomena by means of computer simulations. The main purpose of the simulations is to get insight into the mechanisms behind the described phenomena, not to get accurate predictions and values. The book is aimed at both newcomers into the field, as well as those who are more experienced but want better insight into the acoustics of the contrast bubbles.
