This is the first work to take a comprehensive look at the application of Magnetic Resonance (MR) techniques in the diagnosis, follow-up and therapy monitoring of dementing illnesses. The authors present an overview of MR findings in neurodegenerative and vascular disorders leading to dementia. In doing so, they also discuss other diseases that lead to cognitive and/or behavioural deterioration, such as infectious inflammatory disorders, toxic encephalopathies, inborn errors of metabolism of adult onset and post-traumatic, post-radiotherapy and post-chemotherapy conditions. This authoritative, well-written and richly illustrated reference work is indispensable for anybody working in the field.

MRI is assuming a dominant role in imaging of the larynx. Its superior soft tissue contrast resolution makes it ideal for differentiating invasion of tumors of the larynx from normal or more sharply circumscribed configuration of most of the benign lesions. Over ten years ago CT made a major impact on laryngeal examination because it was the first time that Radiologists were beginning to look at submucosal disease. All of the previous examinations duplicated the infor mation that was available to the clinician via direct and in-direct laryngo scopy. With the advent of rigid and flexible endoscopes, clinical examination became sufficiently precise that there was little need to perform studies such as laryngography which merely showed surface anatomy. The status of deep structures by these techniques was implied based on function. Fortunately laryngography is now behind us together with all of the gagging and contrast reactions which we would all like to forget. CT is still an excellent method of examining the larynx but it is unfortunately limited to the axial plane. With presently available CT techniques motion deteriorates any reformatting in sagittal or coronal projections. The latter two planes are extremely helpful in delineating the vertical extent of submucosal spreads. MRI has proven extremely valuable by producing all three basic projections, plus superior soft tissue contrast. Although motion artifacts still degrade the images in some patients, newer pulsing sequences that permit faster scanning are elimi nating most of these problems."

Many different opinions exist as to the appropriate diagnostic workup and therapy for spinal tumors. With the advent of new imaging techniques and therapeutic regimens, an up-to-date reference work has become an urgent requirement. This book is designed to meet this need, and is the first of its kind to offer an overview of the opinions of internationally renowned specialists in the field. By addressing in detail all of the relevant topics and areas of contention, it should prove of great value in establishing rational imaging and therapeutic protocols for spinal tumors.
