Abstract: A standard X-ray is still the most affordable method of evaluation of patients, including those with spinal diseases since 1895 when X-rays were found and were introduced into general practice. In the standard X-ray examination of the spine and all the anatomical structures located at different depths and different distances, projected onto x-ray film or a screen in the form of planar image. In order to neutralize these drawbacks and to improve visualization, various tomographic techniques have been developed. The most modern and promising diagnostic method is a multisection linear imaging (tomosynthesis), in which a single pass X-ray tube is a series of slices. Digital X-ray tomography with multislice linear are used as a rule, in the world, for examination of breast and lungs. The article presents data on the different types of X-ray tomography in evaluation of patients with tuberculous spondylitis.
Abstract: Development of multilayer digital tomosynthesis technology allows you to get a more accurate imaging of internal organs and tissues in comparison with other traditional radiological methods of investigation, and that is achieved by the possibility of layered imaging of selected anatomical region. Aim: was to analyze possibilities of digital tomosynthesis in the assessment of lung structure in normal anatomy of organs of chest cavity Materials and methods: study include patients without lesions of the chest cavity, who underwent digital tomosynthesis in frontal and lateral projections. Results: basing on analyzed data, we identified features of normal radiological anatomy of the chest cavity using a technique of digital tomosynthesis. Schematically clarified lobar and segmental structure of lungs, as well as airways according to layered imaging. Advantages and disadvantages of the method in imaging of lungs and mediastinal structures are shown. Conclusion: the use of digital tomosynthesis in the evaluation of chest organs allows to determine main anatomical structures of lungs in more detail, through layered imaging and a high spatial resolution.
