Computed tomography creates three-dimensional image with high resolution also, but CT is less available that Biophilia NLS-study, besides, a special attention must be paid to a specific character of contingent of patients with purulent-destructive diseases of lungs and clinical picture of a disease. That is why in practice lung abscess is diagnosed on the basis of clinical symptoms and thorax x-ray data, however with these methods it is not always possible to identify a nature of a nodular shadow in a lung. Application of Biophilia NLS allows to get additional and sometimes decisive information about a pathology, but in this case a therapist must know Biophilia NLS semiotics of lung abscess.

So the objective of this work is to study a picture of lung abscesses and evaluate possibilities of Biophilia NLS of thorax in diagnostics of purulent-destructive process in lungs.
