This volume offers practical guidance in choosing the procedure most likely to answer clinical questions in cardiac nuclear medicine. The emphasis throughout is on establishing and utilizing a systematic approach to test selection and test result analysis, with due consideration given to non-nuclear non-invasive cardiac diagnostic procedures where appropriate. For each of the procedures reviewed, the reader is apprised of the radiopharmaceuticals required, the physiologic mechanisms involved, test acquisition and processing methods, potential technical problems, common pitfalls to avoid, and normal and abnormal findings.
