The value of T1 mapping and intravoxel incoherent motion parameters in predicting PD-L1 expression and dynamically monitoring immunotherapy in advanced lung cancer

T1 mapping and IVIM quantitative parameters may reflect potential trends in predicting PD-L1 expression, have certain value in monitoring the dynamic changes during immunotherapy in advanced lung cancer, and are expected to provide meaningful imaging biomarkers for individualized immunotherapy decision-making.
