A comparative study was made of computerized tomograms of 115 patients, of them 78 suffered from nonspecific chronic pulmonary diseases (chronic bronchitis, bullous emphysema, spontaneous pneumothorax, and fibrosing alveolitis), and 37 patients were healthy. Of all transverse sections the most informative ones were defined, and anatomical reference points were determined for. A conclusion was made that computerized tomograms at 5 most informative levels were sufficient to diagnose changes in each of the lung segments in their diffuse affection. CT standardization was shown to have the same advantages as standardization of layins in routine tomography of the lungs, facilitating comparison over time and reducing radiation exposure of a patient.
