Role of dynamic perfusion magnetic resonance imaging in patients with local advanced rectal cancer

Figure 2 Magnetic resonance imaging study performed for rectal cancer restaging after chemo-radiotherapy with standard T2 weighted sequences and dynamic-contrast enhanced magnetic resonance imaging with 3D-T1 THRIVE images; the corresponding color map and time-intensity curves. A and B: The T2 weighted sequences show a slight thickness in the rectal wall on the left side (from 2 to 5 o'clock) that corresponds to the residual tumor bed; C: The dynamic-contrast enhanced-study show the delineation of the tumor and the time-intensity curves show, with similar curves for the tumor and the healthy rectal wall; D: At histology this patient was classified as a tumor regression grade 1.
