Lung cancer is the malignant tumor with the highest fatality rate in China and even the world,threatening human life and health.Small cell lung cancer(SCLC)represents about 15％of all lung cancers and is the most aggressive subtype of lung cancer.Compared with non-small cell lung cancer,SCLC is marked by an exceptionally high proliferative rate,a strong predilection for early metastasis,and a poor prognosis.Imaging has the unique advantages of simplicity and non-inva-siveness and is widely used in clinical practice as the most basic examination method for lung diseases.How to detect and diagnose SCLC early through imaging examination to intervene on time has become one of the most significant and urgent problems in SCLC diagnosis and treatment strategy.In recent years,imaging examination technology has developed rapidly,in addition to traditional computed tomography(CT),magnetic resonance imaging(MRI),positron emission tomography and computed tomography(PET/CT),but also the emergence of energy spectrum CT and functional magnetic resonance imaging(fMRI).At the same time,the wide application of research methods has also provided substantial help for SCLC's accurate image diagnosis,such as radiomics and deep learning.Therefore,this paper reviews recent research on the ima-ging diagnosis of SCLC,aiming to help us better understand the routine imaging diagnosis of SCLC.
