Highlighted are sagittal fused 68Ga-VQ/PET-CT (a), CT densitometry (b), and StratX® report (c) images from a participant (case 2) demonstrating discordance in modalities in the lower lobes, with high perfusion to lower lobe despite high destruction scores based on CT densitometry. Panel A depicts the right lung with perfusion in color (RUL 42%, RML 12%, RLL 14%), with b showing the CT density. Panel C It indicates right lower lobe having the highest destruction score (70%) despite functional imaging suggesting it had an adequate level of perfusion with one of the higher lobar percentages of normal ventilation/perfusion (30%)
