Oncologic applications of diagnostic imaging techniques.
Before appropriate therapy can be instituted for a cancer patient, the presence and extent of tumor must be evaluated. Deciding which imaging technique to use depends on tumor location, type, and biologic behavior. Conventional radiography provides important information at a relatively low cost compared with other imaging modalities. Ultrasound is a valuable adjunct to radiography, but does not replace it because both imaging modalities provide unique information. Nuclear medicine procedures contribute additional, unique data by providing physiological information, but specificity is lacking. Both CT and MRI provide images with exquisite anatomic detail, but availability and cost prohibit their general use.
