This book provides all the information required for the optimal and practical use of nuclear medicine techniques, which are undergoing rapid development yet remain underutilized. Each chapter focuses on one particular clinical system or disease area. The first section of each chapter describes the nuclear medicine protocols and illustrates normal image patterns observed on commonly and uncommonly performed scans as a reference and explains when and how the procedures should be performed. The following section illustrates both the imaging patterns of different diseases and the diagnostic role of individual studies. Comparisons with other modalities are provided, and the rationale for and effective utilization of each study are discussed. In the 2nd edition of the book, there are above 300 case reviews, a new chapter for radionuclide treatments and new imaging protocols. In addition, the normal patterns on relevant morphologic modalities are documented in an appendix. The book is aimed at Nuclear Medicine physicians and technologists with different levels of training and expertise and also at radiologists who practice nuclear medicine and to radiology residents.
