Abstract
Background: High morbidity and premature mortality in COPD is an indicator of the search for and inclusion of new methods in early diagnosis.
Aim: To determine the role of digital tomosynthesis (DT) in radiation diagnosis and monitoring of COPD.
Methods: The study included 56 patients: 48 men (age 61±3.2 years) and 8 women (age 64±3.6 years). A diagnosis of COPD was made on the recommendation of GOLD 2017. The average length of illness was 28±3.2 years, 80.8% of the subjects were smokers, the smoker index was 31.9±2.1 packs/year. Patients underwent a comprehensive examination. An X-ray examination included the DT scan using the SONIALVIZION 4 apparatus in 2 projections with a digital image processing system. Patients were divided into 3 groups: I - COPD type B (n=17); II - COPD type C (n=8); III - COPD type D (n=31). Patients were comparable in clinical and demographic indicators.
Results: In patients of group I, thickening of the bronchial wall, emphysema, bronchiectasis was detected. In group II, hyper-airiness of the pulmonary fields, an increase of retrosternal space, the presence of bullae and emphysema were revealed. In severe COPD (group III), a low standing of the dome of the diaphragm, limitation of its mobility, increased retrosternal space, narrowing of the heart shadow, depletion of the vascular pattern with simultaneous high density of the walls of the bronchi, the presence of signs of pulmonary hypertension were revealed. DT - a low-dose radiation examination, based on layer-by-layer imaging and high resolution, allowed to detect changes at earlier stages.
Conclusion: The use of low-dose DT in the comprehensive diagnosis and monitoring of COPD is a priority area of radiology.
