The sizes of intra-thoracic lymphatic nodes in normal case identified by multislice сomputed tomography

240 patients without any pathology of lungs were examined to elaborate the algorithm of intra&thoracic lymphatic nodes (ILN) identified by multislice computer tomography (MSCT) determining average and maximum sizes of ILN in sites depending on the age of patients, finding out correlation between size of ILN and the age of patient. 142 men (59.2%), 98 women (40.8%) were studied. MSCT was performed on Light Speed 16ТМ (General Electric Medical Systems) and Aquillion 64 (Toshiba) computer tomographs during maximum inspiration. The analysis of scans was made with the help of eFilm Medical and Vitrea programs. Using the elaborated algorithm helps to identify intra&thoracic lymphatic nodes of 7, 4R, 4L, 10R, 5, 6, 2R, 2L, 10L sites when performing computer tomography of thorax to 240 patients. Average and maximum sizes of lymphatic nodes were determined depending on the age of patient. Minimal sizes were noticed in groups younger than 10 years old and from 11 to 20 years old. The direct correlation depending on the age of patient was strong in 7, 4R, 4L, 10R, 5, 2R, 2L, 10L sites, and moderate in 6 sites. The increasing of ILN is strictly individual depending on sites.
