【Abstract】 PET/CT and PET/MRI are new imaging methods, which can quantitatively reflect biological functions and provide imaging information related to lesions with increasingly widely used. However, the radiation safety problems caused by PET/CT and PET/MRI have also attracted widespread concern. The research progresses of low dose PET/CT and PET/MRI in clinic were reviewed in this article.更多还原
