Abstract:
Radiomics technology extracts high-dimensional quantitative radiomics features from medical imaging to achieve intelligent analysis of nuclear medicine and other medical imaging, which has important application value on improving the diagnostic performance of imaging. However, it has been demonstrated that variability in image acquisition, reconstruction settings, and technological differences can affect the reproducibility of radiomics features, which may lead to variability in the calculations of radiomics models across different centers or scanners, affecting the stability of the performance of radiomics models (i.e., generalizability) in the clinical translation of radiomics models. For this reason, researchers at home and abroad have conducted extensive studies on the influencing factors of radiomics features and harmonization strategies for heterogeneous imaging data in recent years to improve the reproducibility of radiomics features and the generalizability of radiomics models. This paper reviews the above research progress mainly from the aspect of PET imaging in nuclear medicine.
