Variation in SUVmax, Vol-2.5, and Vol-40% as a function of AC method implemented in 4-dimensional PET reconstruction (mean ± SD calculated over all phases and over all six motion patterns)

CT used for AC SUVmax Vol-2.5 Vol-40%
FB CT 8.7% ± 5.6% 4.1% ± 3.2% 5.8% ± 4.5%
Ave-IP CT 6.1% ± 3.0% 5.8% ± 5.3% 6.5% ± 6.7%
Phase-matching 4-dimensional CT 4.1% ± 3.3% 2.9% ± 2.9% 2.6% ± 0.7%

AC, attenuation correction; Ave-IP CT, average intensity projection computed tomography; CT, computed tomography; FB CT, free-breathing computed tomography; PET, positron emission tomography; SD, standard deviation; SUVmax, maximum standardized uptake value.
