Delta radiomics is a novel concept proposed on the basis of radiomics. It can be used to evaluate the dynamic changes of imaging features in the time dimension, reflecting functional information of the tissue.~In clinical practice, liver function can be evaluated by gadoxate enhanced MRI by measuring signal intensity. Most often, simple visual assessment is performed, but quantitative measurements are also done. Theoretically, liver function should also be possible to quantify by using delta radiomics, ie by subtracting MR imaging features obtained in the earlier phase from the latter phase.
To evaluate the feasibility and efficacy of delta radiomics-derived index based on Gd-EOB-DTPA enhanced MRI as a new imaging biomarker for the quantitative assessment of liver function.
