Brachytherapy remains an important component of radical radiation therapy in the modern management of cancer. Widespread adoption of remote afterloading now enables brachytherapy to be delivered with minimum exposure to staff and other patients. Technical advances in imaging and computing power have improved the precision of implantation and complex dosimetry can now be achieved in routine practice. The advantages of direct placement of the radiation source into the area to be treated, overcoming the problems of patient and organ movement, together with the dosimetric advantages inherent in brachytherapy, will ensure that modern brachytheraoy continues to provide the optimal means of delivering accurate high does radiation therapy for many patients.
Fully updated for the second edition, this book provides practical guidance on the use of brachytherapy. Each chapter gives the reader a solid background in the physics and dosimetry of the technique, followed by practical information on its use in common disease sites. Whilst low, medium, and high dose rate techniques are covered, emphasis is placed on high dose rate afterloading techniques which are likely to replace most other forms of brachytherapy in the future.

Radioisotope therapy is an internal form of radiation used to treat cancer; it may be administered orally or intravenously and represents the nearest treatment option to the 'magic bullet', specifically targeting sites of disease whilst sparing surrounding normal tissues. Radioisotope therapy has an important role to play in modern medicine, particularly in the treatment of thyroid disease, neuroendocrine tumours, bone metastasis and non-Hodgkin's lymphoma. It is found in both the diagnostic setting and in therapy, but recently there has been a renaissance in the application of radioisotope unsealed sources in therapeutic indications. It is an active area of research, with the quest for new compounds that will be specific for therapeutic targets. This book is an essential, practical guide to the use of radioisotope therapy, and also includes the background and developmental biology which underpins its use. Individual tumours and diseases are explored, with specific focus given to radioisotope treatment options. The barriers to radioisotope therapy, such as ease of access, acquisition of radioisotopes, radiation protection regulations, and cost are also discussed. ABOUT THE SERIES Radiotherapy remains the major non-surgical treatment modality for the management of malignant disease, with over 50% of patients receiving treatment at some time during the management of their malignant disease.

Das vorliegende Buch ist aus dem Wunsch seiner Kollegen und Mitarbeiter entstanden, Herrn Prof. Dr. Gerd Friedmann zum 60. Geburtstag eine Freude zu bereiten. Hinter dem Konzept steht die Absicht, den Einsatz bildgebender Verfahren in der Diagnostik des akuten Abdomens stichwortartig zu skizzieren und dem Roentgenologen in Fachausbildung und Berufsausubung ein Denk gerust fur den Alltag an die Hand zu geben. Dies erscheint um so notwen diger als die bildgebenden Verfahren in einer explosiven technischen Ent wicklung begriffen sind und jahrlich grundlegend Neu es entsteht und hinzu kommen wird. Der sinnvolle und rationelle Einsatz dieser diagnostischen Methoden wird allein durch die Vielfalt der Moeglichkeiten zwingend. Die richtige Auswahl und die Reihenfolge ihrer Anwendung sind zunehmend fur das Wohl des Patienten und eine wirtschaftlich vernunftige Handhabung von Bedeutung. So mag es auf den ersten Blick erstaunlich sein, wenn der Chirurg als einziger Nichtroentgenologe im Kreise der Autoren erscheint und ein Geleit wort spricht. Dies kann seine Begrundung aber darin haben, dass gerade der operativ tatige Mediziner der naturgegebene Partner des Roentgenologen ist und sich dort, wo die Medizin ernst genommen wird, zwangslaufig ein enges kooperatives Verhaltnis ergeben muss. Vor allem ist der Chirurg in der Lage, Roentgenbefunde zu verifizieren oder Irrtumer aufzudecken. Wie kaum ein anderer ist seinerseits er auf eine exakte Artdiagnose, eine praoperative anatomisch-pathologische Beschreibung, die Darstellung von Nachbar schaftsbeziehungen und funktionelle Beurteilungen, beispielsweise durch angiographische Methoden, angewiesen.

Die nichtinvasive Untersuchung des Herzens und der grossen Gefasse mittels der Magnetresonanztomographie spielt eine zunehmende Rolle bei der Diagnostik von Patienten mit kardiovaskularen Erkrankungen. Dabei hat sich das Verfahren in einigen Standardindikationen bereits als Referenztechnik etabliert. Insbesondere im Bereich der Ischamiediagnostik gibt es jedoch eine Vielzahl neuer Anwendungsbereiche. In diesem Leitfaden fur Kardiologen, Radiologen und technische Assistenten werden die physikalischen Grundlagen und Scantechniken fur weniger erfahrene Anwender verstandlich erklart.

Das Hineinwachsen der MR-Tomographie in die klinische Routine und die Entdeckung neuer Anwendungen vollziehen sich vor unseren Augen schrittweise und doch mit bemerkenswerter Schnelligkeit, ganz ahnlich wie bei der Entwicklung der Computertomographie. Hier wie dort stand zunachst die zerebrale und medullare Diagnostik ganz im Vordergrund. Die systematische Prufung der Methode in anderen Organbereichen, die virtuose Beherrschung des komplizierten Instru mentariums der Physik und der Technik eroeffneten nach und nach weitere Moeglichkeiten. Die Skelettdiagnostik ist dem Radiologen zwar wohl vertraut, dennoch bietet die MR-Tomographie hier Neues und Erganzendes, zweifellos Besonderes aber auf dem Gebiet der Weichteildiagnostik. Aufgrund seines Interesses an der konventionel len Roentgendiagnostik bei Ki10chen- und Gelenkprozessen wandte sich Herr Hohndorf sehr fruhzeitig der MR-Thematik zu und sam melte in Koeln und Aachen Erfahrungen. Er hatte dabei das Gluck, gewissermassen mit dieser neuen Untersuchungstechnik aufzuwachsen und die neuen Moeglichkeiten mit zu erkunden. Von diesen Erfahrun gen aus erster H~md lebt das Buch; es fasst den derzeit erreichten Stand eines interessanten, bisher in dieser Form nicht behandelten Aspekts der sich ausweitenden MR-Diagnostik in pragnanter Form zusammen und gibt damit wertvolle Hinweise sowohl fur die Auswer tung der MR-Untersuchung selbst und als auch fur die Entscheidung zur MRT als weiterfuhrende radiologische Diagnostik. Aachen, im Herbst 1990 Prof. Dr. R. W. Gunther Vorwort Die Magnetresonanztomographie der Knochen, peripheren Weich teile und Gelenke hat sich in den meisten MR-Zentren zum wichtig sten, nichtneuroradiologischen Anwendungsgebiet entwickelt.

Radiotherapy has been one of the principal modalities for the treatment of malignant disease for more than 50 years. From the outset, its advancement has depended on the work of physicists and engineers, in particular for the development of high-energy accelerators for X-ray and electron beams, and in the production of radioactive sources. In addition, the clinical application of ionizing radiations for therapy is based on the foundation of dosimetric concepts and instrumentation. Medical physics plays a pivotal role in many areas, including treatment equipment, dosimetry, treatment planning, and radiation protection.

Radiotherapy physics, second edition is a comprehensive, practical introduction to radiotherapy physics. It provides detailed descriptions of current techniques, written by experienced practitioners who review current methods and give specific guidance in their own areas of expertise. This new edition reflects the significant changes that have occurred in radiotherapy equipment and techniques - the routine use of MLCs, the delivery of IMRT, advances in imaging technology for planning (eg MRI, CT-simulator) and for treatment verification (EPIDs). There have also been significant changes in dosimetry, which have resulted in new dosimetry protocols. Trainee and qualified medical physicists, radiographers, radiation oncologists, and other personnel involved in radiotherapy will find this book to be an excellent guide to this important specialty.

Trauma has been recognized in recent years as one of the most important health care issues still to be fully addressed. A new awareness of deficiencies in the clinical management of injured patients has led to an urgent reappraisal of procedures and training in many hospitals. Parallel to this, there has been a revolution in the field of radiology and diagnostic imaging. Imaging in Trauma provides guidance on the safe and effective application of imaging techniques to patients who have been injured - recommending appropriate techniques wherever they are known to be effective and highlighting cases where their use would be inappropriate. The use of basic conventional radiology is most comprehensively covered, recognising that some of the newer modalities, such as magnetic resonance imaging, will not be generally available for some years. . It is important to consider not only the production of good images, but also how to help clinicians to order them appropriately and to interpret them. A full report from a trained radiologist may not be immediately available to junior medical staff trying to manage the patient in the A&E department. Therefore, advice about viewing images systematically is offered, together with hints on the pitfalls which might be faced. This advice is patient- centred rather than image centred - an emphasis which makes the text different from others. Each chapter offers a summary of the key points it contains. The book will be of assistance to all medical and nursing staff working in the speciality of Accident and Emergency Medicine and also to those working in specialities which offer definitive care to injured patients. The contents of the book may also assist those wishing to study for higher examinations in Accident and Emergency, Surgery and Radiology, especially where the interpretation of images forms part of the examination.
