Brief review of partial volume corrections in PET/CT for lung cancer assessment

The Partial Volume Effect (PVE) is considered as one of the main causes of PET/CT image blurring. The low resulted spatial resolution affects the accuracy of the diagnosis, and makes the staging and the prognosis of lung cancer more difficult. Restoring images through the use of Partial Volume Corrections (PVC) techniques allows a better quantitative estimation of the tumor uptake and a more efficient image analysis. The purpose of this study, is to cover the different approaches proposed in the literature used to correct the PVE in PET/CT in relation with lung cancer.
