From: Influence of rigid coregistration of PET and CT data on metabolic volumetry: a user’s perspective
Bland-Altman plots of relative changes in MTV for different segmentation algorithms. Relative MTV changes for different segmentation algorithms after coregistration to CT1 and CT5 using the RF and RS coregistration algorithm in 28 lesions in 20 patients. Differences are calculated as coregistered data - original data. Solid and dashed lines represent mean ± 2SD.
