Download or read book High Resolution Computed Tomography of the Paranasal Sinuses and Pharynx and Related Regions written by G. Maatman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computed tomography is presently reaching maturity with its high-resolution reconstruction programs, as a result of which conventional tomography has definitely been surpassed. High-resolution computed tomo graphy does indeed provide a better spatial resolution and can provide not only images of surfaces but also of deeper structures as well, such as muscles and fatty areas. Furthermore, it allows examination of the intra cranial contents and examination of possible intracranial tumor invasion. It is therefore necessary to establish the rich potential of normal and pathological images. By writing this book Dr. Gertrude Maatman has undertaken this task and she has performed it well. In particular, I appreciate the way she has treated the CT-anatomy. All normal structures have been methodically identified. In this way, Dr. Maatman conveys the message of the importance of a sound anatom ical basis, which is the only guarantee of a correct interpretation of pathological cases. This atlas will greatly facilitate description of the precise localization of a lesion and its extension to the surrounding structures. I would like to congratulate the author of this highly accurate and didactic work, that should be used by the student as well as by the experienced radiologist. I wish this book every success.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Atlas of Cardiac MR Imaging with Anatomical Correlations written by C. Depré and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic resonance imaging became clinical in 1981 and since that time, has spread in the United States, Europe and Japan like wild fire. The tremendous advantages of the method consisting of safety, superb soft tissue contrast resolution, the ability to study flow, the ability to image in any plane or acquire data in 3D and an almost infinite array of sequences capable of distinguishing between disease and normal tissue, normal and abnormal blood flow make it incomparable for the diagnosis and study of multiple diseases and is particularly valuable in studying the heart and major vessels. The authors of this book have understood that the secret of success of MR imaging in the study of the heart is to combine the knowledge of anatomy of the heart, the coronary vessels, the pericardium and large vessels with the intricacies of MR imaging. This is why they go deeply into the basic principles of NMR, starting from the essentials and going then into detailed techniques of acquiring images from traditional spin echo to gradient echo and ultra fast imaging approaches, such as the multi shot and EPI. The flow phenomena are also discussed in detail from flow and magnetic field gradients diastolic pseudogating.
Download or read book Magnetic Resonance Imaging of Carcinoma of the Urinary Bladder written by Jelle O. Barentsz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carcinoma of the urinary bladder is a common (in the USA it is the fifth most common form of cancer in males and tenth most common form of cancer in females) malignan cy and one in which noninvasive staging by imaging plays such an important role. This book presents a complete approach to MR imaging of carcinoma of the urinary bladder from a detailed discussion of the value of MRI in the diagnosis of the urinary bladder to the history of the procedure. The technical discussion of the general principles of MRI including the optimal pulse sequences to be used and factors that influence the quality of images are included in this book. The safety factors are also presented along with contraindications. The application of a double surface coil with the field strength of O.5T provides the fine quality of the illustrations. The atlas of comparative anatomy by MRI on normal volunteers and post-mo'rtem specimens as well as MR images on patients with bladder tumors and post-surgery specimens is unique. The results of the clinical imaging stu dies in patients with carcinoma of the bladder, comparing the relative value of clinical staging, MR, CT and lymphography, are helpful in showing the advantages of MRI.
Download or read book Endosonography written by B.D. Fornage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the development of gray-scale imaging, real-time scanning, Doppler examination, and high-frequency sonography, endosonography is one of the latest major breakthroughs in the history of diagnostic ultrasound. Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effective, easy-to-use endosono scopic probes. Because the transducer can be placed in direct contact with or close to lesions, high frequencies (up to ~2 MHz) can be used, yielding cross-sectional images of unsurpassed resolution. The availability of specially designed intracorporeal probes for specific natural cavities that are routinely explored by conventional (optical) endoscopy or palpation has significantly expanded the diagnostic applications of sonography. Transrectal and transvaginal examinations are now performed routinely in many institutions, and virtually all sonographic equipment manufac turers have in their line of products at least one endorectal and one endovaginal transducer. Most endosonoscopic probes connect to existing scanners, and for radiology departments, the invest ment for transrectal or transvaginal scanning will usually be limited to the purchase of the specific probe. In this book, clinical applications of endosonography (excluding transesophageal echocardio graphy) are covered by European and North American experts. Current equipment and techniques of examination are described in detail to help newcomers get started in the field of endosonography.

Download or read book Magnetic Resonance Imaging of Bone and Soft Tissue Tumors and Their Mimics written by A.M.A. de Schepper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic resonance imaging has already become a most valuable imaging modality in the diagnostic work-up of musculoskeletal neoplasms. While high accuracy of MRI for staging purposes has been proven, we will focus in this monograph on the characterization of primary bone and soft tissue tumors by MRI. The major purpose of this monograph is to provide an atlas of magnetic resonance features of primary bone and soft tissue tumors for radiologists, orthopedic surgeons and physiotherapists. The results presented are based on investigations of 94 primary bone and soft tissue tumors and mimicking conditions by magnetic resonance imaging. Although the scale of the material allows for statistical handling, the number of patients per subgroup is too small to come to definite conclusions. We will therefore limit ourselves to the description of and comments on a great number of cases to illustrate the diagnostic potential of this new imaging modality. We would like to thank the anonymous cooperators: referring clinicians, pathologists, nurses, technicians and secretaries whose help enabled us to present this monograph. We would also like to express our gratitude to the firms Siemens AG and Schering AG for technical support.

Download or read book MRI of the Brain Head Neck and Spine written by Jaap Valk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growing number of MR installations, clinicians and radiologist are being confronted more and more with visual information they do not feel as confident with as with the more 'mono-form' infor mation of conventional radiographs, CT and US. The freedom of parameter choice ofthe MR operator allows the same object to be depicted in various ways and the contrast in the images to be changed and inverted at will. For those not experienced in interpreting MR images, this may cause confusion and uncertainty about their diagnostic content. This will sometimes lead to an unnecessary retreat to other diagnostic modalities. The purpose of this book is to help close the gap between MR operators and readers and clinicians. A variety of cases is presented, together with the MRI considerations. In nearly all these cases, confirma tion of diagnosis was obtained by histological examination. Quite deliberately, this book only includes the occasional CT scan or angiography for comparison, to avoid the temptation of falling back on other modalities and of escaping from the often more difficult to interpret, but in the end more rewarding MR images. All the MR images in this book were made with a 'first-generation', unsophisticated Teslacon I, 0.6 T, superconducting magnet system. Hopefully, they will reflect the quality of the machine. Some people will agree with me that it is sad that investments in expensive health care systems are subject to the whims of those who are mainly interested in satisfying their stockholders.
