TP53 and head and neck squamous cell carcinoma: Rasmussen et al. analyzed perfusion (mean Ktrans) and diffusion (ADCmean) parameters in a mixed HNSCC group that included 14.3% OPSCC and 24% lymph nodes and observed positive correlations between the p53 percentage values in both Ktrans (partial correlation: 0.193; p = 0.015) and ADCmean (partial correlation r = 0.190; p = 0.010) [60].
