Repeatability of ¹⁸F‐<scp>FDG PET</scp> radiomic features: A phantom study to explore sensitivity to image reconstruction settings, noise, and delineation method

Abstract

Feature space reduction and repeatability of ¹⁸ F-FDG PET radiomic features depended on all studied factors. The high sensitivity of PET radiomic features to image quality suggests that a high level of image acquisition and preprocessing standardization is required to be used as clinical imaging biomarker.
