[Comparative evaluation of the diagnostic efficiency of interactive digital radiography and routine fluorography in screening examinations of the chest].
The current trend for decreased exposure to medical ionizing radiation sources contributes to the introduction of novel technologies into radiation diagnosis. The aim of this study was to compare the informative value of interactive digital X-ray study and routine enlargement fluorography. The study covered 316 individual without the complaints typical of lung diseases. Three roentgenologists assessed X-ray images by 7 major signs. The sensitivity, specificity, and accuracy of the methods in question were defined. The final stage was the construction of routine operating curves (ROC). When there were diffuse changes in the lung, the sensitivity of interactive digital X-ray study was 14% higher. The higher informative value of interactive digital X-ray study is also attested by the higher position of a respective ROC. The fact that lung tissue function in combination with low radiation load may be estimated assumes the use of interactive digital X-ray study in patients with pneumosclerosis and emphysema.
