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). 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 Hunter 4025  metapathia system (the IPP, Russia) 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 Hunter 4025  metapathia-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 Hunter 4025  metapathia-study of thorax was carried out after roentgenography with following comparison of results. Further on both diagnostic methods were applied simultaneously, but frequently Hunter 4025  metapathia-study preceded roentgenography or replaced some part of it.
