[Use of high resolution algorithm in computerized tomography of disseminated lung diseases].

Lobule of the lung is a principal anatomical structure of the respiratory zone in the lungs. Secondary lobule of the lung consists of about fifty primary lobules and is delineated by fibrous interlobular septa. Each lobule is delineated by interlobular septa and blood is supplied by small arterioles of pulmonary artery system. Its shape is conical and size ranges from 10 to 22 mm. The author used algorithm of high resolution in HR CT to present normal distal generations of respiratory area of the lungs and the same in 32 patients with disseminated lesions to the lungs. It is known, that lobule of the lung may be involved in very important pathologies. The author shown that significant architectural rearrangement takes place in pulmonary lobules and adjacent areas in the course of disseminated pulmonary diseases. The process include thickening of interlobular septa, consolidation of lobular area, changes in the shape of lobuli, and appearance of small cysts. The use of HR CT enables imaging in such pathologies which normally are inaccessible to conventional radiologic examinations.
