We have attempted to clarify the role of computed tomography in the detection of occult metastases and show why it is currently the best method of evaluating the thorax in patients with a known extrapulmonary primary tumor. Further improvements in specificity and sensitivity await refinement of other imaging modalities, such as tumor or antitumor radioisotopic labeling and in vivo magnetic resonance imaging.
