  1. ADC apparent diffusion coefficient; Nx: 9 patients were categorized as Nx because they underwent palliative surgeries which could not completely meet the requirements for N staging
  2. The values of the ADC parameters were presented as median (interquartile range)
  3. *: P < 0.05 (independent-samples Kruskal-Wallis test)
  4. †: The independent-samples Kruskal-Wallis test for N staging didn’t include those 9 patients who were categorized as Nx
