Objective To investigate the clinical value of dual-source CT dual-energy imaging in de-artifact imaging of bone and joint metal. Methods The imaging data of 37 patients who underwent dual-source CT dual-energy scanning post-metal fixation of bone and joint trauma were collected from April 2015 to October 2017 in our hospital. The resulting 80kV and 140kV data were linearly fused and the resulting images were taken as the observation group. The images were simulated by conventional 120 kV reconstruction and the obtained images were control group. Both MPR, VR and MIP were performed in the control group and the observation group. The clinical value of reconstructed image quality and artifact was also observed. Results The image quality of the observation group was 91.89% (102/111) on average, while that of the control group was on average 43.24% (48/111). The observation group was superior to the control group, with significant difference in image quality between the two groups (P<0.05). In the observation group, there was almost no artifacts in the images, accounting for 92.79% (103/111). There was almost no artifacts in the control group (36.94%, 41/111). The observation group was superior to the control group, and the difference of artifacts produced by the two groups was statistically significant (P<0.05). Conclution Dual-source CT dual-energy imaging can effectively remove metal artifacts in the internal fixation of bone and joint, and can clearly show the internal fixation of bone and joint. And the display of bilateral psoas muscle is very clear, this technology provides clinical imaging information, it has an important guiding role.
