[Quantitative Imaging Assessment of Tumor Response to Chemoradiation 
in Lung Cancer]

Precision medicine demands accurate assessment of tumor response to therapies with the purpose of timely optimization or adjustment of the given treatment regimens. Chemoradiation remains the standard of care in advanced lung cancers and imaging-based noninvasive response evaluation could improve therapeutic efficacy and reduce treatment-related severe side effects. In this review, we overviewed the applications and pitfalls of major imaging modalities in response evaluation in lung cancer from a quantitative perspective. The development of radiomics will provide more precise information for treatment predicting, evaluation and prognosis.
