Multimodal imaging evaluation in staging of rectal cancer

Figure 2 Stage T2 and T3 rectal cancer detected by magnetic resonance imaging. A: T2-weighted magnetic resonance image shows an intraluminal polypoid mass (arrows) confined to the intact, hypo-intense muscularis propria (arrowheads), suggestive of a T2 cancer; B: T3 lesion is seen as a tumor (arrows) that extends through the hypo-intense muscle layer into the perirectal fat (arrowheads).
