Abstract
Objective: To investigate the effect of different concentration contrast agents on the image quality of the lower extremity venography with multi-slice spiral CT. Methods: The patients received direct method lower extremity venous examination were collected from 2014 to 2016 in our hospital.The injection rate of contrast medium was 3ml / s,the delay time was 50s and the scanning time was 20s.The images were divid-ed into groups according to the different concentrations,and the original image data were acquired. The origi-nal image data were acquired and analyzed by image reconstruction. The images were evaluated and analyzed statistically. Results:In this group of 40 patients, 80 sides of the lower extremity deep vein, the scores of each group were as follows: the concentration of 1: 4 group, 1 points for 13.04%, 2 points for 52.17%, 3 points for 34.79%;concentration of 1:6 group,1 points for the 11.11%,2 points for 22.22%,3 points for the 66.67%;the concentration of 1:7 group,1 point for 18.18%,2 points for 18.18%,3 points for 63.64%;the concentration of 1:9 group,1 points for the 0,2 points for 24%,3 points for 76% cases. Conclusion: This study demonstrates the use of contrast media at a contrast agent concentration of 1:6,1:7,1:9 can get a clear image of blood vessels.But the concentration of contrast agent set 1:9 not only can provide the best clin-ical image data,but also reduce the amount of contrast agent,can be considered the best venous CTV of the lower extremity concentration.关键词
