Fig. 1.

Box plots for ADCmean and ADCmin (in 10^-3 mm²/s), SUVmean and SUVmax values for local tumour recurrence and benign post-treatment lesions. Median values (black lines), first and third quartiles, and whiskers indicating data minimum and maximum. Median values for tumour recurrence (interquartile range): ADCmean = 1.09 (0.95–1.18), ADCmin = 0.71 (0.45–0.89), SUVmean = 5.27 (3.62–7.93), SUVmax = 9.29 (5.03–11.04). Median values for benign lesions (interquartile range): ADCmean = 1.55 (1.25–1.87), ADCmin = 0.93 (0.59–1.26), SUVmean = 2.47 (1.91–3.25), SUVmax = 3.57 (2.52–5.3). The difference between median values for recurrent tumours and benign post-treatment lesions was statistically significant (p < 0.001)
