Download or read book MRI Contrast Agents written by Sophie Laurent and published by Springer. This book was released on 2016-11-03 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the multiple aspects of (i) preparation of the magnetic core, (ii) the stabilization with different coatings, (iii) the physico-chemical characterization and (iv) the vectorization to obtain specific nanosystems. Several bio-applications are also presented in this book. In the early days of Magnetic Resonance Imaging (MRI), paramagnetic ions were proposed as contrast agents to enhance the diagnostic quality of MR images. Since then, academic and industrial efforts have been devoted to the development of new and more efficient molecular, supramolecular and nanoparticular systems. Old concepts and theories, like paramagnetic relaxation, were revisited and exploited, leading to new scientific tracks. With their high relaxivity payload, the superparamagnetic nanoparticles are very appealing in the context of molecular imaging but challenges are still numerous: absence of toxicity, specificity, ability to cross the biological barriers, etc.

Download or read book Tissue Perfusion Quantification Using Magnetic Resonance Imaging and Contrast Media written by Jean-Paul Vallée and published by . This book was released on 1999 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse décrit une approche originale de mesure de la perfusion tissulaire basée sur l'imagerie par résonance magnétique (IRM) et l'injection intraveineuse de produits de contraste. Les grands principes de la technique d'IRM ainsi que les différentes classes de produits de contraste sont passés en revue. Puis, les séquences d'impulsions RF utilisées pour la mesure de la perfusion tissulaire sont étudiées, suivies des méthodes de conversion du signal en concentration de produit de contraste. Enfin, la dernière partie présente deux classes de modèles permettant de mesurer la perfusion tissulaire à partir des courbes de transit obtenues avec l'IRM qui ont été développées durant cette thèse. La méthode proposée dans cette thèse démontre qu'il est possible de mesurer d'une manière non invasive par IRM le débit de perfusion tissulaire ainsi que cela a été vérifié dans quelques situations cliniques.

Covers the basic chemistries, MR physics and the most important techniques used by chemists in the characterization of MRI agents from every angle from synthesis to safety considerations. Is written for all of those involved in the development and application of contrast agents in MRI. Presented in colour, it provides readers with true representation and easy interpretation of the images. A word from the Authors: Twelve years after the first edition published, we are convinced that the chemistry of MRI agents has a bright future. By assembling all important information on the design principles and functioning of magnetic resonance imaging probes, this book intends to be a useful tool for both experts and newcomers in the field. We hope that it helps inspire further work in order to create more efficient and specific imaging probes that will allow materializing the dream of seeing even deeper and better inside the living organisms. Reviews of the First Edition: "...attempts, for the first time, to review the whole spectrum of involved chemical disciplines in this technique..."—Journal of the American Chemical Society "...well balanced in its scope and attention to detail...a valuable addition to the library of MR scientists..."—NMR in Biomedicine

Download or read book MRI of the Body written by Daniel Vanel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with the introduction of x -ray computed tomography, much of the initial development of magnetic resonance applications tended to focus on the central nervous system. The development of magnetic resonance imaging applications to other organ systems such as the chest, abdomen, pelvis and extremities has lagged somewhat behind, awaiting technical improvements, and a broader user base. The past two years have seen a marked increase in imaging applications throughout the body, most notably the musculoskeletal system. It is in this regard, that MRI of the Body is a welcome arrival as a text which describes both basic principles of magnetic resonance ima ging and surveys the current status of magnetic resonance imaging applications throughout the body. The volume is concise, focused, clinically oriented, and abun dantly illustrated. In each organ system, the appropriate technical approach is discussed, the normal anatomic features are reviewed, and the range of pathologic appearances which may be encountered are described. The authors of the chapters provide a balanced overview of MR applications and describe both present limitations and future potential of magnetic resonance imaging applications in the organ system described.

This book was released on 2001-04-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a huge increase in the use of MRI and contrast agents in medicine in recent years as evidenced by a big increase in the number of hospitals with MRI machines and the ever-increasing number of examinations using contrast agents. Contrast agents have revolutionized the use of Magnetic Resonance Imaging (MRI) in medical diagnostics, allowing doctors to distinguish between normal and abnormal tissues and ultimately improving prognosis for the patient. This monograph covers all aspects of production, use, operating mechanisms and theory of these diagnostic agents, used to produce high contrast images in MRI. It will therefore be unique resource for what is currently a very active domain of research both in universities and in industry. The Chemistry of Contrast Agents in Medical Magnetic Resonance Imaging is a comprehensive treatise: * written by the most active scientists in the field of contrast agents for medical MRI - from both university and industrial backgrounds * covering the topic from every angle from synthesis to safety considerations * invaluable to physicists, chemists, biologists as well as physicians * the first in-depth coverage of this topic
Download or read book Contrast Agents I written by Werner Krause and published by Springer Science & Business Media. This book was released on 2002-01-22 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracellular MRI and X-ray contrast agents are characterized by their phar- cokinetic behaviour.After intravascular injection their plasma-level time curve is characeterized by two phases. The agents are rapidly distributed between plasma and interstitial spaces followed by renal elimination with a terminal half-live of approximatly 1–2 hours. They are excreted via the kidneys in unchanged form by glomerular filtration. Extracellular water-soluble contrast agents to be applied for X-ray imaging were introduced into clinical practice in 1923. Since that time they have proved to be most valuable tools in diagnostics.They contain iodine as the element of choice with a sufficiently high atomic weight difference to organic tissue. As positive contrast agents their attenuation of radiation is higher compared with the attenuation of the surrounding tissue. By this contrast enhancement X-ray diagnostics could be improved dramatically. In 2,4,6-triiodobenzoic acid derivatives iodine is firmly bound. Nowadays diamides of the 2,4,6-triiodo-5-acylamino-isophthalic acid like iopromide (Ultravist, Fig. 1) are used as non-ionic (neutral) X-ray contrast agents in most cases [1].
