Progress in quantitative imaging evaluation of tumor spatial heterogeneity / 中华放射肿瘤学杂志

ABSTRACT

Tumor heterogeneity is characteristic in malignant tumors. It is a new challenge in imageology to achieve the visualization of tumor heterogeneity and precise quantification using modern imaging techniques. To solve this problem,the newly emerging radiomics is applied to analyze tumor spatial heterogeneity,with a visualization effect.Image quantification methods,including histogram analysis,texture analysis,and parametric response mapping, can accelerate the research and development of new drugs, improve the efficacy prediction,modify the treatment regimen,and promote the prognostic evaluation.
