In recent years

radiomics

as hot topic in the research of clinical medicine

has been widely explored in various tumors (including breast cancer) and achieved satisfying progresses. Although the traditional imaging modes remains most common methods for diagnosing and evaluating breast cancer

positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) based radiomics represent great potential to clinical application for therapeutic and diagnostic purpose due to its ability of simultaneously presenting morphological and functional characteristics. Recently

the studies on PET/CT or PET/MRI based radiomics in breast cancer have emerging on the literature over the world

especially in the last two years

PET radiomics have made great progress in differential diagnosis

metastasis assessment

molecular typing prediction

efficacy of monitoring prediction and prognosis prediction. In this manuscript

a comprehensive review of PET/CT or PET/MRI based radiomics in breast cancer were provided

its facing challenges and possible solution were also included.
