A total of 104 patients with tumors of the upper portions of the tracheobronchial tree were examined. The tumors were malignant in 66 cases (53 primary and 13 secondary ones) and benign in 38 cases. The sensitivity of CT in the diagnosis of blastomas of the trachea and the main bronchi made up 96.12%, specificity 86.15%, and accuracy 91.6%. CT permitted the detection of the tumor, specification of its site and size, definition of its contour, imaging of a non-transparent portion and of relationships with the adjacent organs and tissues, assessment of the status of the walls (by detecting dense, thickened, or deformed sites) and regional lymph nodes. |
