From: More accessible functional lung imaging: non-contrast CT-ventilation demonstrates strong association and agreement with PET-ventilation

Fig. 2

Ventilation images for patient 12, chosen as representative of the mean Spearman correlation between the CTVI modalities and Galligas PET. Images are normalised to the median ventilation value within the lung mask. Regions of visibly lower activity on the PET image with corresponding low functioning regions on the CTVI are marked with white arrows. Some areas visibly appear to be mismatched - indicative areas of low ventilation on CTVI that do not appear on other modalities have been indicated with red arrows
