The use of FDG-PET/CT and diffusion-weighted magnetic resonance imaging for response prediction before, during and after preoperative chemoradiotherapy for rectal cancer

Figures & data

Figure 1. Box plot of ΔSUV_max during and after CRT, correlated with pCR.

Figure 2. Box plot of initial ADC value correlated with pCR.

Figure 3. Accuracies of the individual and combined threshold values for ΔSUV_max during and after CRT.

Figure 4. The ΔSUV_max during (a) and after (b) CRT set out against initial ADC values. Patient with a pCR after CRT are depicted as a (□). Patients with no pCR after CRT are depicted as (▴).

Figure 5. Accuracies of the individual and combined threshold values for the initial ADC value and the ΔSUV_max during CRT are depicted in (a). The accuracies of the individual and combined threshold values of the initial ADC value and the ΔSUV_max after CRT are depicted in (b).
