Clinical value of computed tomography-based three-dimensional reconstruction of the pelvis and mesorectum in middle to low rectal carcinoma

Figure 4 Three-dimensional reconstruction of rectal mesenteric-related volumes in different orientations. A: Anterolateral view: Rectal mesenteric fat at the level of the superior border of the third sacral vertebra (α); B: Lateral view: Rectal volume at the level of the superior border of the third sacral vertebra (β; semi-translucent rectal mesenteric fat); C: Anterolateral view: Rectal mesenteric volume at the level of the superior border of the third sacral vertebra ((γ = α + β) and pelvis; D: Lateral view: Rectal mesenteric volume at the level of the superior border of the third sacral vertebra (γ) and pelvis.
