[Diagnosis of tumors of the trachea and main bronchi by computerized tomography].
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.

[Role of computerized tomography in stenoses and other diseases of the trachea and main bronchi].
Fifty-one patients with stenosis of the upper portion of the tracheobronchial tree of various origins were examined; the sensitivity of computer-aided tomography (CAT) in the diagnosis of stenoses of the trachea and the main bronchi was found to be 95.83%, specificity 98.31%, and accuracy 93.87%. CAT is superior to other methods of investigation (common tomography, tracheobronchoscopy) in the detection of changes in the tracheobronchial walls and the tissues adjacent to the trachea and the main bronchi. CAT is particularly valuable for the diagnosis of the causes of compression stenosis. The method permits specification and recognition of the type of involvement in traumatic injuries (6 cases), tracheoesophageal fistulae (6 cases), post-tuberculous processes (3 cases). CAT examinations are truly valuable in the diagnosis of osteoplastic tracheobronchopathy (3 cases), some other rare diseases (tracheobronchomegaly--1 case, scleroma--1 case, amyloidosis--2 cases). The authors recommend the optimal algorithm of examinations of patients with diseases of the upper portions of the tracheobronchial tree: roentgenoscopy--roentgenography--CAT--tracheobronchoscopy.
