Abstract:
Objective To investigate application value of dual energy CT nonlinear fusion technology in diagnosis of liver diseases.Methods 86 patients with liver disease screening from 2013 January to 2014 December in our hospital were selected as the research objects.All patients underwent dual energy CT nonlinear fusion and linear fusion imaging,image quality was compared between the two groups of image results,and compared the hepatic lesion area and normal hepatic tissue,change analysis of portal vein of hepatic lesions.Results Nonlinear fusion image CT value difference of (59.71 ±7.64)Hu higher than the value difference linear fusion images of CT (31.35 ± 10.53)Hu,the difference was statistically significant(t =4.361,P <0.05);nonlinear fusion image contrast to noise ratio of liver lesion,hepatic signal -to -noise ratio was (2.94 ±1.06),(5.62 ±1.53),which was higher than that of linear image fusion(4.84 ±2.36),(8.35 ±1.09),the differences were statistically significant(t =1.914,2.059, all P <0.05).Conclusion The use of dual energy CT nonlinear fusion technology can significantly improve the ima-ging quality of CT for liver parenchyma and portal vein without increasing the scanning phase conditions,and nonlinear fusion image for lesions of imaging is linear fusion image clearer,especially small lesions,help to improve the clinical liver lesion detection rate,clinical value.
