Mediastinal imaging in lung cancer.
Sixty-six patients with lung cancer underwent mediastinal staging with gallium scanning, CT scanning and mediastinal exploration at mediastinoscopy and/or thoracotomy. Histological findings at time of mediastinal exploration were correlated with the results of the non-invasive staging scans. Gallium scanning had an accuracy of 78.8 per cent and CT scanning had an accuracy of 77.3 per cent. There was no evidence of increased test accuracy by performing both scans in the same individual. Either scanning technique may be utilised as a simple non-invasive mediastinal staging procedure, and where negative it is appropriate to proceed directly to thoracotomy.
