Abstract

Medical images represent maps of the spatial distribution of tissue properties. Each modality probes a specific set of tissue properties such as x-ray attenuation for computed tomography, transmission of sound for ultrasound, and the rate of glucose uptake for fluorodeoxyglucose–positron emission tomography. Understanding the basic principal underlying each modality is important for developing approaches to utilize imaging in cancer research and clinical care. In addition, each modality has specific challenges related to reliable quantitation that are important to appreciate.

Voxar, Inc. produces products that compete with products listed in this paper (to M. A. B.).The study design was approved by the National Cancer Institute Cancer Therapy Evaluation Program. Computerized tomographic colonography examinations for American College of Radiology Imaging Network Protocol A6656 were submitted by E. G. McFarland, Mallinckrodt Institute of Radiology, St. Louis, Missouri; M. Zalis, Massachusetts General Hospital, Boston, Massachusetts; C. D. Johnson, Mayo Clinic, Rochester, Minnesota; M.

Morrin, Beth Israel/Deaconess Hospitals, Boston, Massachusetts; and J. Yee, Veterans Administration Hospital, San Francisco, California. Workstations for performing computerized tomographic colonography interpretations were loaned to the American College of Radiology (ACR) by General Electric, Vital Images, and the Mayo Clinic. Each provided technical support for installation at the ACR. Computerized tomographic colonography examinations were removed and workstations returned after the study interpretations were completed.
