PET/CT: Essentials for Clinical Practice, edited by Drs. Workman and Coleman, provides an introductory reference source for physicians who want to learn more about PET/CT, as well as for medical students and residents who are involved in the rapidly growing ?eld of PET/CT. The ?rst two chapters of the text outline the basic principles involved in patient preparation, imaging interpretation, and reimbursement. The remainder of the text provides information necessary to make a learned and informed de- sion with regard to the appropriate use of PET/CT in oncologic, cardiac, and neurologic disorders. An important factor in determining the value of any text is the knowledge and credentials of the editors. Dr. Coleman's background as a leader in the ?elds of nuclear medicine, PET, PET/CT, and reimbursement places him at the fo- front in the knowledge of the subject matter. Dr. Workman, having trained with Dr. Coleman, is eminently suited to co-edit a text of this nature. PET/CT: Essentials for Clinical Practice is a well-written introductory text, and it provides fundamental information to improve understanding and clinical applications of this rapidly-evolving imaging modality. The next decade will involve the ?eld of functional/molecular imaging with a variety of innovative instrumentation developments, allowing us to examine smaller components of the human body with greater accuracy.
