Abstract：Objective To investigate the clinical value of dual energy CT imaging nonlinear fusion technology in improvement of
the value of intestinal image quality. Methods A retrospective analysis was conducted on 30 patients who underwent the intestinal
dual energy CT imaging. The optimal Blending Center and Blending Width (including axial, MPR, MIP and VR) images were
obtained by Optimum contrast function in Dual-Energy software. Then we imported all the viewing images into Viewing software for
measurement of objective image quality. The intestinal wall thickening sites of all images were selected to measure CT values and
the background noise of aorta, intestinal wall thickening, and spinal column. The signal-to-noise ratio and contrast to noise ratio were
also calculated. All of the image quality was scored by 2 diagnostic imaging physicians with rich experience through double blind
method. Results There was no statistical difference between the two groups of images of aortic and intestinal wall enhancement
in the venous phase. The two groups of image background noise, signal-to-noise ratio and contrast to noise ratio is statistically
significant, t values were 3.8, 4.6, 4.2, respectively, all P values were less than 0.05, in which the nonlinear fusion image quality is
superior to conventional 100 kV image. Conclusion Dual energy CT nonlinear fusion technology can improve the image quality of
intestinal imaging, improve the image diagnosis rate and excellent rate, with potential clinical application value.
