Although orthopantomography (OPT) is a very frequently employed radiological examination, even the expert radiologist can encounter difficulty in reporting the findings owing to the specific terminology, the nature of the diagnostic queries, and the need to describe precisely the clinical implications for the dentist. Additionally, artifacts are a frequent occurrence, and many radiologists and dentists are unfamiliar with their causes and solutions. Methodological inaccuracies during the execution of OPTs also have important clinical implications. For all of these reasons, this richly illustrated monograph on OPT sets out to describe in detail diverse technical and methodological aspects of the examination, from image acquisition through to artifact generation due to lack of experience or malfunctioning. Possible solutions are suggested for all of the most common diagnostic and methodological problems. Emphasis is placed on appropriate terminology and guidance offered on the interpretation of findings in a range of conditions, including the most common odontological problems. This book will be of great value to the radiologist in routine interpretation and reporting of OPTs.

by Mario Banche, M.D. IX The neologism "coloscopy" (colonscopy, colonoscopy) is the latest addition to the vocabulary of endoscopy of the large intestine. just as the term "duodenoscopy" was in endoscopy of the upper digestive tract a few years ago. With the advent of the coloscope it is now possible to examine the large bowel more extensively and effectively than was formerly possible with the use of its rigid forerunner, the rectosigmoidoscope. The earliest rectoscopes, 11 endoscopes" introduced during the 19th century by Segales and Desormeaux (1826, 1853), were conceived for many uses-inspection of the urethra, bladder, uterus, rectum. Successive improvements eventually led to the construction of an instrument designed exclusively for endoscopy of the rectum and sigmoid colon (Bensaude, 1907). Over the following years the rectoscope underwent no substantial change and thus an abundant and homogeneous literature accrued in which the available instruments and their use were described while the endoscopic pathologic nosography and corresponding endoscopic pictures of the rectum and sigmoid colon were codified, illustrated first by simple sketches and later by still and motion photography. The literature contains many excellent publications, some in monograph form.

Diffusion Tensor Imaging (DTI) is a variation of diffusion-weighed imaging. Particularly in the neurosciences, this technique has gained tremendous momentum in the past decade, both from a technical point of view as well as in its applications. DTI is mainly used in neurological diagnosis and psychiatric and neurologic research, e.g. in order to locate brain tumors and depict their invasivity.

DTI offers a unique in-vivo insight into the three-dimensional structure of the human central nervous system. While easy interpretation and evaluation is often hampered by the complexity of both the technique and neuroanatomy, this atlas helps you recognize every one of the important structures rapidly and unambiguously.

In the introduction, this atlas provides a concise outline of the evolution of diffusion imaging and describes its potential applications. In the core part of the atlas, the neuroanatomically important structures are clearly labeled both on DTI-derived color maps and conventional MRI. Complex fiber architecture is illustrated schematically and described concisely in textboxes directly on the relevant page. In the final part of the atlas, a straightforward, step-by-step approach for the three-dimensional reconstruction of the most prominent fiber structures is given, and potential pitfalls are indicated.

The atlas aims at neuroscientists, neuoanatomists, neurologists, psychiatrists, clinical psychologists, physicists, and computer scientists. For advanced users, the atlas may serve as a reference work, while students and scientists are thoroughly introduced in DTI.
