Figure 5 Dynamic-contrast enhanced magnetic resonance imaging study performed for restaging of rectal cancer after chemoradiation therapy with 3D-T1 THRIVE and T2 weighted sequences; the corresponding color map and time-intensity curves. A: The T2 weighted sequences show a slightly hypointense thickness in the rectal wall on the anterior side (from 11 to 2 o’clock) that corresponds to the fibrotic residual tumor bed; B: The dynamic-contrast enhanced-study performed after chemo-radiotherapy show that on the T1 THRIVE sequence some tissue thickness is present (12 o'clock) and the corresponding time-intensity curves show a significant difference between the healthy rectal wall and the tumor; C: At histology was classified as a tumor regression grade 3.
