Figure 2

Classification of elastography findings. A: Normal type: the wall of the colon was not thickened (less than 4 mm), and the layer structure was observed in B-mode. Almost all parts of the wall appeared green in EG-mode, but the second layer was sometimes red. B: Homogeneous type: the wall was thick in B-mode but the layer structure was unclear. The thick wall was almost completely green in EG-mode. C: Random type: the wall was thick in B-mode and the layer structure was unclear. Various colors (red, green, blue) were mixed throughout the thick wall in EG-mode. D: Hard type: the wall was thick in B-mode and the layer structure was unclear. The thick wall was almost completely blue.
