Impact of Time-of-Flight and Point-Spread-Function for Respiratory Artifact Reduction in PET/CT Imaging: Focus on Standardized Uptake Value.

Year: 2017

Type: article

Abstract: BACKGROUND: The most important advantage of positron emission tomography/computed tomography (PET/CT) imaging is its capability of quantitative analysis. The aim of the current study was to choose the proper standardized uptake value (SUV) threshold, when the time-of-flight (TOF) and point spread function (PSF) were used for respiratory artifact reduction in the liver dome in a new-generation PET/CT scanner. MATERIALS AND METHODS: , at different thresholds (i.e., at 45%, 50%, and 75%), were also assessed. RESULTS: varied from 10.58±14.99% up to 35.49±32.60% (which was dependent on reconstruction parameters). CONCLUSION: can be an accurate semi-quantitative parameter for PET/CT images, for all lesion sizes. For smaller lesions, however, a smaller filter size was required to observe an accurate SUV.
