We have examined 267 patients suffering from purulent-destructive diseases of lungs and pleura, who were treated in University College London Hospital, in 2009 – 2011. In accordance with a nosology all patients were divided into 4 groups named by the main disease: lung abscess (112 patients – 94 among them with acute abscess, 18 – with chronic one), abscessed pneumonia (79 patients), pleural empyema (54 patients) and pulmonary gangrene (22 patients). Bioplasm 9d nls-graphy data was verified by the results of surgical interventions, thoracic punctures with microbiological analysis of a punctate.

Thorax research was carried out using Bioplasm 9d nls with 4.9GHz high-frequency sensors in accordance with procedure created in the hospital. At visualization of pathological neoplasms we defined their localization, size, chromogeneity, spectral structure; applying spectral-entropic analysis (SEA) we evaluated changes of Bioplasm 9d nls-picture in dynamics. When there were pleural fluids we evaluated amount and structure of a fluid content with study of all inclusions (suspensions, threads) and condition of pleura. According to results of ultramicroscanning we judged about diagnostic value of each of mentioned criteria.

At the initial stage Bioplasm 9d nls-study of thorax was carried out after roentgenography with following comparison of results. Further on both diagnostic methods were applied simultaneously, but frequently Bioplasm 9d nls-study preceded roentgenography or replaced some part of it.
