| Abstract: | Time of flight(TOF) and high definition(HD) reconstruction are the latest technologies to improve the performance of PET.In this article,the image quality and quantitative analysis were compared among TOF+HD,HD,TOF+iterative and iterative reconstruction through NEMA body phantom studies and clinical case analysis.TOF improved quantification and detection of smaller lesions through providing higher contrast,while HD significantly increased the SUV and T/B values in all size.Good understanding of these techniques may be useful for selection of the corresponding PET/CT systems. |
