Fig. 6From: Associations between dynamic-contrast enhanced MRI and tumor infiltrating lymphocytes and tumor-stroma ratio in head and neck squamous cell cancerSubanalysis of HPV negative tumors. DCE-MRI values: a Spearman’s correlation analysis between TIL expression within the tumor compartment and entropy derived from Ktrans (r = 0.61, p = 0.03). b Spearman’s correlation analysis between TIL expression within the tumor compartment and mean derived from Ve (r = − 0.66, p = 0.01). c Spearman’s correlation analysis between tumor-stroma ratio and entropy derived from Ktrans (r = 0.67, p = 0.009)Back to article page
