RESUMEN
The study included 40 patients aged 33-71 years with chronic pulmonary obstruction (CPO) and diabetes mellitus (DM). They were examined by multilayer CT with detailed analysis of parenchymal tissues. The main microvascular changes in lung parenchyma included dilation, focal opacity (2-5 mm), and beaded vessels. In patients with isolated CPO, these changes were less pronounced than in those with combined pathology. All patients presented with bronchial deformities, bronchoectasia, emphysema, and cysts. Microvascular pathology in lung parenchyma appears to be a manifestation of universal diabetic microangiopathy responsible for the unfavourable development of CHD in DM patients.

A device is described intended for digital recording and reproduction of x-ray images attached to RUM-20M x-ray diagnostic complex with x-ray image amplification. Radiation loading of patients and the staff were reduced more than twofold. Spot photographs during x-ray examinations were ruled out. The quality of hard copies of images made using various printing devices are compared.

The authors propose a procedure and equipment for control by using a rotation table of a PYM-20M X-ray system with an image intensifier. A 4 x 4-cm beam field is used. The procedure makes it possible to lower X-ray loads in patients by 10-15 times, to calculate the absorbed integrated radiation dose, to enhance the quality of plane films, to draw up a protocol of studies. This increases the accuracy of X-ray anatomic instrument position. The apparatus can be remotely controlled.
