This widely used text is now fully updated to reflect the broad acceptance and availability of PET, including instrumentation and special radiation safety aspects. Also added are new information on radiopharmaceuticals, newer scintillation materials (BGO), fusion imaging (PET/CT and SPECT/CT), descriptions of SPECT filters, discussions on contrast detail curves, and radiation effects on cell culture. An easy-to-read format and eye-friendly internal design facilitate learning and guide readers through essential details, examples, and true-to-life problems. A testing component at the end of each chapter offers key points for review with questions and answers.
