CORRELATION OF POSITRON EMISSION TOMOGRAPHY PERFUSION-VENTILATION MATCHING WITH CT DENSITOMETRY IN SEVERE EMPHYSEMA.

Correlation with functional measures of ventilation or perfusion varies widely and no prior study has evaluated correlation between densitometry and lobar ventilation/perfusion in patients with severe emphysema. The aim of this study was to evaluate the utility and findings of Gallium-68 ventilation/perfusion positron emission tomography-CT ( SP 68 sp Ga-VQ/PET-CT) in severe emphysema assessment.
