Impact of PET/CT image reconstruction methods and liver uptake normalization strategies on quantitative image analysis.

Background: In oncological imaging using PET/CT, the standardized uptake value has become the most common parameter used to measure tracer accumulation. The aim of this analysis was to evaluate ultra high definition (UHD) and ordered subset expectation maximization (OSEM) PET/CT reconstructions for their potential impact on quantification.

Patients And Methods: We analyzed 40 PET/CT scans of lung cancer patients who had undergone PET/CT.
