Figure 1

Illustration of measurement of the tumor maximal extramural depth. (a) HRT2WI obtained from a 56-year-old male patient with rectal cancer (PT4N1) showed that the distance from the outermost boundary of the tumor to the residual muscularis was 2.02 cm. (b) HRT2WI obtained from a 69-year-old male patient with rectal cancer (PT3N0) showed that the distance between the attachment in the two muscularis propria breakthroughs and the outermost boundary of the tumor was 1.63 cm.
