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

However, these differences did not reach statistical significance ( p = 0.360, p = 0.321, p = 0.345, p = 0.686, and p = 1.000, respectively) ( Table 3 , Figure 1 ). 3.5 Comparison of quantitative parameters pre- and post-immunotherapy between the effective and ineffective groups The pre-treatment T1 and ADC values of the effective group were higher than those of the ineffective group.
