Figure 3 The EUS elastography images of GIST (A) and GIL (B). The pictures were print-screened from Photoshop CC in the process of hue histogram analysis. We obtained Figure A from a patient with GIST and Figure B from a patient with GIL by use of the elastography system in our hospital. In these pictures, the left side shows EUS and EUS elastography images and the right side shows the hue histogram of the region of interest (ROI), circled by a dotted line in the left side as the picture. There are 4 channels – RGB, R, G, and B – in the hue histogram and mean hue histogram values, and their standard deviations were calculated as 70.71±30.34 (A) and 53.29±30.15 (B) in the RGB channel.
