Fig. 3From: A proper protocol for routine 18F-FDG uEXPLORER total-body PET/CT scansTotal-body 18F-FDG PET MIP images of different scan times reconstructed by OSEM and HYPER Iterative in a patient with lung cancer injected with half dose18F-FDG. a 18F-FDG PET MIP images of 10Â s, 30Â s, 1Â min, 2Â min, 3Â min, 4Â min and 5Â min, respectively, reconstructed by OSEM. The quality of OSEM-10Â s, OSEM-30Â s, OSEM-1Â min and OSEM-2Â min images was low due to low counting rate and large signal noise, especially the OSEM-10Â s and OSEM-30Â s. The OSEM-3Â min image reached the high quality, either that of OSEM-4Â min and OSEM-5Â min. b 18F-FDG PET MIP images of 10Â s, 30Â s, 1Â min, 2Â min, 3Â min, 4Â min and 5Â min, respectively, reconstructed by HYPER Iterative. The quality of HYPER Iterative-10Â s, HYPER Iterative-30Â s and HYPER Iterative-1Â min had lower signal noise and higher quality than the counterparts by OSEM although they were still not excellent. The HYPER Iterative-2Â min image reached the high quality, either that of HYPER Iterative-3Â min to HYPER Iterative-5Â minBack to article page
