Dynamic Contrast-Enhanced Magnetic Resonance Imaging in Oncology by Alan Jackson,David L. Buckley,Geoffrey J. M. Parker Pdf
Dynamic contrast-enhanced MRI is now established as the methodology of choice for the assessment of tumor microcirculation in vivo. The method assists clinical practitioners in the management of patients with solid tumors and is finding prominence in the assessment of tumor treatments, including anti-angiogenics, chemotherapy, and radiotherapy. Here, leading authorities discuss the principles of the methods, their practical implementation, and their application to specific tumor types. The text is an invaluable single-volume reference that covers all the latest developments in contrast-enhanced oncological MRI.
Clinical MR Imaging by P. Reimer,P.M. Parizel,F.-A. Stichnoth Pdf
This book offers practical guidelines for performing efficient and cost-effective MRI examinations. By adopting a practical protocol-based approach the work-flow in a MRI unit can be streamlined and optimized. All chapters have been thoroughly reviewed, and new techniques and figures are included. There is a new chapter on MRI of the chest. This book will help beginners to implement the protocols and will update the knowledge of more experienced users.
I am particularly pleased to be able to write the introduction to this book that resulted from a collaborative effort by the Radiology De partment, under the auspices of the Boerhaave Committee for Postgraduate Medical Education of the Faculty of Medicine, at the University of Leiden and the Department of Medical Imaging and Radiological Sciences at Van derbilt University. Magnetic resonance imaging affords the opportunity to interrogate organ and system structure and function in a nondestructive manner without se rious biological implications. Tissue contrast with this modality is ex quisite and inherently superior to that of x-ray computed tomography. The advances to improve signal capture, development of rapid data acquisition techniques, fabrication of more appropriate pulse sequences, and availa bility of contrast agents portend increased versatility and specificity of these studies. Despite the proliferation of numerous general and specialized texts, the developments in MRI occur at such a pace that data in these references are necessarily dated. The technical horizon of MRI is vast with almost li mitless possibilities of signal generation and plan reconstruction. Tissue contrast is so importantly affected by the coupling of signal generation and capture that collective experience of institutions and investigators is extremely important to the initiate and useful even to those indivi duals with the greatest clinical experience.
Medical Imaging Contrast Agents: A Clinical Manual by Sukru Mehmet Erturk,Pablo R. Ros,Tomoaki Ichikawa,Suzan Saylisoy Pdf
This volume highlights and broadens our understanding of the correct use and the possible contraindications of contrast agents applied in radiology. Written by experts in the field, it not only focuses on the chemistry, physiochemical properties and pharmacokinetics of both iodinated and gadolinium-containing contrast agents, but also on the relevant safety issues such as frequency of their short- and long-term side effects and ways to avoid them nephrotoxicity risk related to the iodinated contrast agents NSF (nephrogenic systemic fibrosis) accumulation of gadolinium in the brain use of contrast agents in pediatric patients and pregnancy It also includes essential data on the use of contrast agents, such as scanning protocols, in the context of various clinical conditions. This comprehensive manual addresses all professionals involved in radiological imaging and is an invaluable tool for radiologists and technologists, as well as for residents and clinicians.
MR Contrast Agents, An Issue of Magnetic Resonance Imaging Clinics - E-Book by Marco Essig,Juan Gutierrez Pdf
MRI contrast agents improve visibility of internal body structures. This issue offers a complete, practically focused review of the use of a variety of contrast agents for MR Imaging. A contrast agent not only must be safe, but also efficacious and cost-effective, and the articles in this issue address all three of these concerns and the uses of contrast agents for a variety of applications.
Clinical MR Imaging by Peter Reimer,Paul M. Parizel,Falko-A. Stichnoth Pdf
In 15 years MRI has evolved into an essential modality, developing from being a preferred neuroimaging method to becoming a whole-body, comprehensive imaging approach. For this, various coils, pulse sequences, and contrast media have been developed. The complexity of the factors to consider often represents an obstacle not only to beginners but also to more experienced technicians and physicians. Since routine diagnostic questions represent more than 90% of clinical examinations, the intention of the editors and authors was to provide an understandable book for this purpose. The book gives practical information about performing effective and efficient MR examinations in daily practice. Solving clinical questions with new sequences should no longer be difficult for beginners in the field.
Clinical Low Field Strength Magnetic Resonance Imaging by Hans-Martin Klein Pdf
This book covers all aspects of low field MRI, describing its advantages, problems and prerequisites. Individual chapters are devoted to site planning, safety considerations, coils, imaging technique, image quality optimization, the imaging of different anatomic regions and likely future developments. The factors that must be borne in mind when selecting a low field system are clearly identified and detailed attention is paid to the applications for which such a system is adequate. The focus on high field systems has led to a situation where only a few systems with field strengths lower than 0.5 T survive. Some of these systems possess high field features such as multichannel coils and strong gradients; furthermore, sequence technology and image processing techniques taken from higher field strength systems have resulted in impressive imaging capabilities. While 1.5-T systems will probably continue to remain the standard, low field systems offer advantages such as the feasibility of dynamic joint examinations, improvement of T1 contrast, reduction of “missile effects” and decreased radiofrequency exposure. Low field strength MRI consequently has the potential to contribute to optimal patient management and given comparable image quality, its application may become an issue of patient safety. This book will be an invaluable asset to all who are involved in planning and/or running a low field strength MRI facility.

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].
