The radiomics is gradually applied to positron emission tomography (PET) imaging with the development of radiomics. More cell biology information can be obtained from PET radiomics
as the cell metabolism reflected by PET imaging is more closely related to biological behavior. PET radiomics has made great progress in tumor diagnosis
treatment response assessment
prognosis prediction
and molecular typing. In this article
we reviewed the application and challenges of PET/computed tumography(CT) radiomics in tumor management.
