“…Bland-Altman [20] and correlation plots were generated for all patients in each group for both SUVmean and SUVmax. Known for their variability in their density [14], CT quantification of the lungs was also calculated to compare their variability and the potential impact of assigning them a unique LAC (0.022 cm −1 ).…”

“…Despite these techniques are showing promising results in time of flight (TOF) systems its usefulness and stability is still to be proven and further investigations are needed to evaluate their application in non-TOF scanners. Whole-body techniques are scarce because of the particularities and challenges imposed in both atlas-and segmentation-based methods: misregistration problems and tissue segmentation/classification failures due to the difficulties in lung segmentation and the proximity of bone and air [4, 9], as well as the inter- and intra-subject variability of the lungs’ density [14]. Finally a new methodology based on simultaneous emission and transmission image acquisition has been recently developed [15].…”

“…Relative low-density regions are indicative of high tissue destruction within the lung and/or the presence of hyperinflation [13]. There are different methods that can be used to quantify these relatively low-density regions, including characterizing air volume and tissue mass for regions across the lung [14].…”

“…3 CT measures of emphysema correlate well with pathology, 4 and numerous studies have shown a strong correlation between spirometry and CT emphysema. 512 The agreement between CT emphysema and spirometry is however not perfect, and in some cases, CT densitometry may be more sensitive in detecting emphysema than spirometry. 6,13 …”
