Possibilities of x-ray computer densitometry in diagnosis of occupational hypersensitivity pneumonitis
The article presents results of assessing lung parenchyma density within X-ray diagnostic pattern “Opal glass” in patients with changes characteristic for occupational hypersensitivity pneumonitis(60 patients) and interstitial pneumonia (65 patients of reference group) vs. reference group (70 individuals), by modified method of X-ray computer tomography of high resolution. Quantitative characteristics as native parameter (HU units), density gradient (IDG), with consideration of homogeneity degree of the evaluated zone by SD value enabled considerable objectification of the changes direction in diagnostic monitoring of the studied lung disorders.
