Figure 2 Sagital T2 weighted high resolution magnetic resonance image of the rectum. These demonstrate (A) circumferential mid-rectal tumor (arrow head). In addition there is a sub-centimeter pre-sacral node in close proximity to the superior rectal artery (arrow). (Although this is sub-centimeter it has the same signal intensity to the tumor); B demonstrates response to neo-adjuvant short course chemoradiotherapy (45 Gy over 25 fractions plus capcetabine 825 mg/m2 days 1 to 35). This demonstrates significant response of the tumor mass, with high signal intensity in the mucosa likely to be treatment related. The pre-sacral node has resolved.
