Figure 15. Axial T₂ weighted MRI examination and corresponding histopathology section. Multiple tumour deposits are demonstrated (arrow), which lie within 5 mm of the mesorectal fascia, but not within 1 mm of the fascia. Although this tumour distribution indicates a poor prognosis, the circumferential resection margins are predicted as being clear of tumour. The corresponding histopathology section demonstrates clear surgical circumferential resection margins (arrowheads).
