RATIONALE AND OBJECTIVES The aims of this study were to determine the extent of emphysema in individual lobes and to investigate whether the lobar distribution of emphysema influences pulmonary function. METHODS Helical CT and pulmonary function tests were performed in 50 emphysema patients. Percentages of low attenuation volume (extent of emphysema) were calculated for each lobe by using CT densitometric analysis. RESULTS The extent of emphysema of the whole lung in these patients was 44… CONTINUE READING
