Computed Tomographic Assessment of the Mediastinum in Patients with Lung Cancer

Abstract
57 patients with histologically or cytologically proven lung cancer underwent computed tomography (C.T.) of the thorax as part of a staging procedure. All were considered potentially resectable.22 of these patients have been the subject of a previous report.19 patients had malignant involvement of the mediastinum, and C.T. Scanning detected 16 of these (Sensitivity = 84%). In 38 patients with a clear mediastinum, the Scan report was correct in 29 (Specificity = 76%). There were 3 false negative and 9 false positive results.
