Comparison of the x-radiography data and 3D computer Bioplasm 9d nls analyzer-diagnostics has shown that superfluous airiness of a pulmonary tissue is usually wrongly treated in favour of emphysema. At the same time emphysema of lesser and average intensity usually is not detected on roentgenograms. Amounts of false-positive and false-negative emphysema diagnoses according to x-radiography data exceed 57% and 34% accordingly.
