Radiomics is the hotspot in medical imaging research recently
which is known as a high throughput quantitative analysis for comprehensive evaluation of tumor biological characteristics. It filters and analyses the quantitative features extracted from objective regions of CT
MRI or PET. Radiomics develops the precise treatment of lung cancer with unique advantages of non-invasiveness
high repeatability and high efficiency. This paper aimed to elaborate the roles of radiomics in diagnosis
treatment
efficacy evaluation of lung cancer on the basis of reviewing literatures about its application in lung cancer and summarizing its basic processes and the current challenges.
