[Efficiency of Quantitative Analysis of Lung Computed Tomography Findings in Patients with Chronic Obstructive Pulmonary Disease].
To evaluate the efficiency of detection of emphysema in the analysis of lung computed tomography (CT) images using the “Autoplan” program and to compare the data of quantitative analysis and clinical indicators. Material and methods. Sixty patients with chronic obstructive pulmonary disease (COPD) were examined; the diagnosis was confirmed by external respiratory function evaluation; all the patients underwent inspiratory-expiratory CT using a 32-row multidetector CT scanner, followed by postprocessing in the “Autoplan” system. The features of the system were a floating threshold value, constructing a histogram, and the possibility of preserving a report and polygonal models. Echocardiography was performed to evaluate the right heart and to estimate pulmonary arterial pressure. ⋯ Thus, analysis of the lung density CT characteristics provides a physician with objective numerical values, which affect the progression of obstructive changes in patients and the development of signs of chronic cor pulmonale.

[Computed tomography in evaluating the development of different types of pulmonary fibrosis in patients with interstitial lung diseases].
to assess the favorable and unfavorable types of lung tissue fibrotic changes in patients with interstitial lung diseases (ILD) detected by high-resolution computed tomography (HRCT). MATERIAL AND METHODS. The results of examinations were analyzed in 385 patients: 181 with respiratory organ sarcoidosis, 130 with fibrosing alveolitis, 36 with histiocytosis X, and 38 with lymphangiolciomyomatosis. All the patients underwent HRCT; the data were compared with the results of comprehensive functional study of external respiration (CFSER), histological examination (in 70.1%), and the pattern of the disease. ⋯ The type of pulmonary fibrosis development is one of the major prognostic criteria for he course of ILD. HRCT makes it possible to assess its clinical picture as a whole and to reveal the type of development of fibrotic changes, their extent, the degree of involvement of the tracheobronchial tree in the process (formation of different types of bronchiectasis), concomitant extrapulmonary changes that may be clinically and functionally relevant (chest bone frame deformation, varying pleural changes, vascular disorders). Estimation of prognosis of the disease is most effective in comparing clinical, morphological, HRCT, and CFSER data.

[Radiographic morphometry of intervertebral spaces of the vertebral column in health and dystrophic changes in the intervertebral disks].
To develop a radiographic morphometric procedure for estimating the sizes and shapes of intervertebral spaces in the thoracic and lumbar spine and to evaluate the status of intervertebral spaces in women in health in terms of their age and in dystrophic transformations of intervertebral disks. ⋯ The sizes and shape of intervertebral spaces show a number of regularities associated with the position of a segment in the vertebral column. In the bulk of the thoracic spine, the vertebral spaces are biconvex in shape and those in the transient thoracolumbar area and in the lumbar segment were posterior wedge-shaped. The age-related changes in the sizes and shape of intervertebral spaces are associated with their slight dilatation at the age of 70 years or older, without their normal shape being impaired. When dystro- phic intervertebral disk changes develop, there is a moderate narrowing of intervertebral spaces in the lower half of the vertebral column in conjunction with a wedge-like alteration in intervertebral discs, their shape.

Case Reports Comparative Study[The first experience in using elastography in combination with endobronchial ultrasonography for mediastinal pathology: Preliminary assessment of feasibility and comparison of characteristics via different approaches].
To preliminarily assess the feasibility of elastography in endobronchial ultrasonography and to compare characteristics via different accesses. ⋯ Endobronchial ultrasonography elastography is technically feasible. The wall of the trachea and bronchi has no significant impact on the quality of an obtained image; elastographic data are reproducible during re-measurements. Comparison of elastographic characteristics through different approaches suggests that there is a tendency to overestimate data on lymph node density during endobronchial examination versus a transesophageal approach. Thus, the direct transfer of the accumulated data and patterns of elastographic diagnosis to an endobronchial approach is impossible and likely to require a revision of criteria to estimate malignancy-associated changes during its application.

Comparative Study[Comparative analysis of the informative value of 18F-fluorodeoxyglucose and 11C-methionine positron emission tomography in the differential diagnosis of solitary lung masses].
To study the possibilities of enhancing the efficiency of differential diagnosis of solitary lung masses by optimizing the quantitative analysis of positron emission tomography (PET) data when two radiopharmaceuticals (RP) (18F-fluorodeoxyglucose (18F-FDG) and 11C-methionine) are used alone and in combination. ⋯ When RP is used alone, the diagnostic efficiency of C-methionine PET in the differential diagnosis of lung tumors and inflammations is higher than that of 18F-FDG PET. At the same time, the highest PET is seen when 18F-FDG and 11C-methionine are used in combination.
