双源CT双能量非线性融合技术提高 肠道图像质量的研究
Study of Clinical Value of Dual Energy CT Imaging Nonlinear Fusion Technology in Improvmeng of the Intestinal Image Quality
摘要
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, allP 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.关键词
