Book Description
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.

Book Description
Notwithstanding the important role of direct clinical and endoscopic examination in modern management of pathological conditions of the larynx, radiological study the and, more specifically, cross-sectional imaging by CT and MRI make definite diagnostic contributions by virtue of their potential to display superbly the deeper extent of laryngeal lesions. Indeed, remarkable progress has been achieved during recent years in CT and MRI techniques as applied to the neck region. This book sets out to provide a sorely needed update of our knowledge of the diagnostic potential of these cross-sectional methods and constitutes a very welcome addition to our series "Medical Radiology", which aims to cover all important clinical imaging fields of modern diagnostic radiology. It will be of great interest to general and head and neck radiologists as well as to ENT surgeons and radiotherapists. Professor R. Hermans and the other distinguished contributors to this work are internationally renowned experts in the field and they have accumulated vast experi ence and a wealth of radio-pathological knowledge of the larynx over the years. I would like to congratulate them most sincerely for this outstanding volume, its comprehensive contents and its superb illustrations. I hope that this book will meet with the same great success as previously published volumes in the series. I would appreciate any constructive criticism that might be offered.

Book Description
This open access book offers an essential overview of brain, head and neck, and spine imaging. Over the last few years, there have been considerable advances in this area, driven by both clinical and technological developments. Written by leading international experts and teachers, the chapters are disease-oriented and cover all relevant imaging modalities, with a focus on magnetic resonance imaging and computed tomography. The book also includes a synopsis of pediatric imaging. IDKD books are rewritten (not merely updated) every four years, which means they offer a comprehensive review of the state-of-the-art in imaging. The book is clearly structured and features learning objectives, abstracts, subheadings, tables and take-home points, supported by design elements to help readers navigate the text. It will particularly appeal to general radiologists, radiology residents, and interventional radiologists who want to update their diagnostic expertise, as well as clinicians from other specialties who are interested in imaging for their patient care.

Book Description
This concise integrated handbook looks at all available imaging methods for head and neck cancer, highlighting the strengths and weaknesses of each method. The information is provided in a clinical context and will guide radiologists as to the information the clinician actually needs when managing a patient with head and neck cancer. It will also provide the clinician with the advantages and limitations of imaging. The text therefore deals with Ultrasound, CT and MRI. The initial chapters aim to give the reader a core knowledge, which can be used in imaging by the various methods described. The subsequent chapters are directed towards clinical problems and deal with the common cancers in a logical order.

Book Description
Carcinomas of the larynx and hypopharynx present unique challenges when it comes to their assessment and management. Management involves the essential dilemma of optimizing cure rates while also ensuring that potential disability due to compromised airway, voice and swallowing is minimized. Treatment decisions involve careful disease assessment, judicious multispecialty decision-making, and subsequent meticulous implementation of the selected treatment modalities. The critical nature of each of these steps has led to dramatic advances in assessment techniques (radiology, endoscopy and photography, stroboscopy, narrow band imaging, contact endoscopy) and also in treatment methods (radiation therapy, combined concurrent chemo-radiation, combined sequential chemo-radiation, trans-oral CO2 laser and robotic surgery, partial laryngectomy, total laryngectomy, extended total laryngectomy). As such, treatment decisions have become increasingly complex with the twin objectives of maximizing cure as well as function preservation and are based on tumor stage, tumor location, systemic co-morbidities, nutritional status, patient priorities, and social and economic factors. This multidisciplinary book has been written by a team of editors with considerable experience and expertise in these critical areas and a deep understanding of teamwork and the strengths and limitations of individual technologies and treatments. It presents a homogeneous and unbiased view that is applicable to all specialties involved in the care of larynx and hypopharynx cancers.
