Can drug development and evaluation be improved by the use of positron emission tomography (PET)? PET is now well established and many PET centres participate in networks that warrant the quality of their research. PET allows one to follow the effect of a drug on a variety of patients' metabolic parameters. In addition, PET may be used to follow the fate in vivo of a compound, allowing visualisation of its binding to specific receptors and a direct study of the mechanism of drug action in normal and pathological situations. The book shows the fields in which PET offers new and unique information for the development of drugs (conception, toxicity, pharmacokinetics and metabolism, clinical research, and relations between clinical and biological effects) and evaluates fields in which PET may shorten the development time of drugs. Audience: Professionals in the pharmaceutical industry in all areas of drug discovery and pharmacology, pre-clinical testing, pharmacokinetics and metabolism, clinical evaluation, registration and regulatory affairs. Government health authority representatives who assess data and documentation on new drug development and radiopharmaceuticals. Academic experts concerned with any of these areas.

Despite 50 years of antibiotics, infection remains a major source of both morbidity and mortality. Immunosuppression, either secondary to drugs in transplant recipients or secondary to HIV, has expanded the number of microorganisms that are known to be pathogenic in man. Imaging of infection has a vital role both in the initial diagnosis and in the continuing management of patients with infection or suspected infection. Functional imaging using nuclear medicine techniques has a unique role to play in identifying sites of infection in a wide range of patients with varying clinical conditions. This book, written by a series of experts not just in the fields of nuclear medicine but also infectious disease and radiology, discusses the role of nuclear medicine in three parts: a review of the pathophysiology of infection; a technical description of those nuclear medicine techniques which can be used in imaging infection; an extensive systematic review including thoracic, abdominal and orthopaedic infection as well as a special section on the acutely ill patient, the immunosuppressed patient and the patient with pyrexia of unknown origin. This book will be of interest to all clinicians looking after patients with infection and who need to use imaging techniques. It will also be of use to radiologists and nuclear medicine physicians who will be using these techniques clinically.

Single Photon Emission (Computer) Tomography (SPECT or SPET) is an important tool in nuclear medicine. The volume presents a basic guideline to the technology involved and discusses the application of the method to the investigation of various anatomical regions of the body.

Safety and Efficacy of Radiopharmaceuticals was established as a very important and comprehensive subject at the First Europe an Symposium on Radiopharmacy and Radiopharmaceuticals in Denmark in 1983.

Just prior to the 1982 Annual Meeting of the European Thyroid Association in Brussels, a number of outstanding experts in the field of X-ray fluorescence gathered at the Academisch Ziekenhuis of the Free University of Brussels in a joint effort to more clearly define the actual place and value of the latest newcomer among the techniques available for the in vivo assessment of thyroid function. It is the merit of Prof. M. Jonckheer to have organised this meeting and to have made available the work presented there to a larger public in the form of this monograph. Both, the meeting and the written accounts thereof are greatly appreciated by all thyroidologists who care for properly defining the genuine value of X-Ray fluorescence in scientific research and in clinical management of thyroid disorder. Three main conclusions can be drawn from the work presented 1. X-ray fluorescence has become a safe, convenient and reliable tool for measuring intrathyroidal iodine stores in vivo with an inter-assay reproducibility estimated at roughly 10% 2. X-ray fluorescence, used by expert hands, is a highly interesting tool to follow changes of intra thyroidal iodine stores in time, subsequent e. g. to the exposure of the thyroid gland to excess iodine 3. In contrast, no definite place of X-ray fluorescence as a technique in routine assessment of thyroid disease is yet at the horizon This latter conclusion may appear somewhat disappointing.

Although the clinical importance of hypoxia imaging is obviously great, to date neither the clinical nor the scientific community at an international level has focused many research activities on the hypoxia problem.

AIMS OF THE COLOGNE-SYMPOSIUM ON RADIOLABELLED PLATELETS In 1976, M. Because of its physical characteristics (2.8 days half-life, 94% gamma emission) 111 Indium turned out to be the best isotope for platelet kinetic studies as well as for the measurement of platelet incorporation by Thrombi to be used up until now.

The publication of this volume, which is based upon presentations made to the Third European Symposium on Radiopharmacology at Noordwijkerhout, April 22 - 24, 1982, is indicative of the continued interest in this sub-branch of Nuclear Medicine.

Safety and Efficacy of Radiopharmaceuticals was established as a very important and comprehensive subject at the First Europe an Symposium on Radiopharmacy and Radiopharmaceuticals in Denmark in 1983.

Radiophannaceuticals labeled with short-lived radionuclides are utilized to unravel biochemical processes, and to diagnosis and treat diseases of the living body are-developed through extensive evaluation in ~iological models.

Next the text follows the usual pattern of discussion on the pharmacodynamics of radiopharmaceuticals, followed by a description of various clinical disease patterns of the liver and the use of cholescintigraphy in evaluating these diseases.

In a fast developing field there might be tendencies to confrontation between interests and there have certainly been some tendencies to put undue restrictions on the use of radio pharmaceuticals due to the lack of understanding between the industry and the regulatory authorities and between regulatory authorities and hospitals.
