For more than two decades, this text has succinctly presented the procedures and technologies related to an ever-changing specialty. This 6th edition continues that tradition by providing a general update of all chapters, a new chapter on CT physics and instrumentation, and a revised focus to the increasingly important PET/CT systems. All aspects of nuclear medicine are explored, with a focus on pertinent anatomy and physiology and a discussion of each procedure in relation to the specific use of radiopharmaceuticals and instruments required.
