Abstract：Objective To study the effect of different reconstruction methods in Neuwise positron emission tomography/computed
tomography (PET/CT) of Neusoft on the image quality and standardized uptake value (SUV) value of 18F-FDG PET/CT.
Methods The data of patients who underwent full-body 18F-FDG examination with Neuwise PET/CT in our department from
October 2019 to June 2020 were retrospectively collected, and the reconstruction analysis of the phantoms and real scan images
was conducted using different built-in reconstruction methods of Neuwise PET/CT, such as time of flight (TOF), maximum
a posteriori (MAP), TOP+point spread function (PSF) and TOF+PSF+MAP. The impact of different reconstruction methods
on image quality and related SUV was compared. Results The built-in PSF and MAP reconstruction methods of Neuwise PET/CT both
optimized PET image quality at different degrees, and the combination of two methods further optimized the Neuwise PET/CT image quality
without side effects. Conclusion It is recommended to choose both the PSF and MAP reconstruction methods, simultaneously on
the basis of TOF after examination using Neuwise PET/CT 18F-FDG whole-body imaging to obtain high-quality images and more
precise SUV values.
