[Potentialities of digital low-dose x-ray apparatus in the diagnosis of heart and lung diseases].

The paper presents experience in clinically testing a digital low-dose X-ray apparatus. X-ray studies were performed in 169 patients: 140 with cardiovascular abnormalities and 19 with lung diseases. The findings show the high quality of images of thoracic aorta and lung structures. The radiation dose received during an examination is many times lower than at routine X-ray study and fluorography, which makes it possible to use the apparatus in mass surveys of contingents at risk for tuberculosis.
