NLS-research Of 9D NLS New Prospects For Evaluation Of Lungs And Pleura Changes

Traditional roentgenologic methods still remain the basic in diagnostics of pulmonary organs diseases, but non-linear diagnostic research (NLS) of thorax organs opens conceptually new prospects for evaluation of lungs and pleura changes. Information about a pathological process is presented in a form of three-dimensional image with strict differentiation of various in spectral properties biological structures, at the same time application of ultramicroscopic scanning makes possible to study researched object in every detail. The study is not related to radiation exposure, it does not require expenses for additional equipment if a standard set of NLS-diagnostic devices is available. That is why at the present moment it finds more extensive application in diagnostics of lungs and pleura diseases and with increasing frequency becomes a topic of scientific works.

NLS-research with 9D-NLS of thorax is an informative, radiologically safe method of purulent-destructive lungs and pleura diseases diagnostics, allowing to not only acquire additional information, but to carry out primary examination and dynamic monitoring. NLS-semiotics of pathological changes in a lung is diverse and depends, first of all, on focal or diffuse character of lung affection. Analysis of NLS-picture makes possible to define a character and severity a purulent-destructive process in a lung (acute purulent or gangrenous abscess, abscess forming pneumonia, gangrene), its spreading to pleural cavity (empyema, pyopneumothorax). The common factor, which determines NLS-picture of purulent cavity at abscess and abscess forming pneumonia, is a condition of its spontaneous drainage, which is evaluated by quantity and character of distribution of achromogenic air areas in a cavity. The main symptom of pleural empyema is a presence of a thick chromogeneous suspension in pleural fluid; at pyopneumothorax achromogenic air areas appear. NLS-semiotics of gangrene is quite diverse due to the greatest severity of destructive changes and is formed by focal and diffuse changes in a lung, although its clinical course may be characterized by prevalence of one of these variants.
