Chest radiography or computed tomography in the assessment of lung cancer prior to radiography.
A series of 93 patients with lung cancer were considered for intensive radiotherapy, and investigated by chest radiography and computed tomographic (CT) scan. Spread of tumour was detected radiologically to lymph nodes, pleura or chest wall on 98 occasions. Of these, 16 were shown by both investigations, but in 82 the spread was revealed only by CT examination. Clear visualization of the tumour prior to radiotherapy is important to select those patients who would benefit from radical radiotherapy, to allow accurate treatment planning, and to allow, in subsequent follow-up, monitoring of the response to radiotherapy. In this study tumour was clearly visualized in 59 patients treated, but in 31 (53%) of these only by the use of computed tomography.
