Abstract: Objective To understand the medical pure carbon dioxide gas as a contrast agent arterial image quality and clinical value. Method Application of super-selective arterial catheterization, the catheter was inserted into the internal iliac artery and in patients with uterine artery, The use of one-time medical carbon dioxide bags for carbon dioxide angiography and use iodine for angiography. Set the basic principles of image quality assessment, Develop appropriate standards for image quality assessment and two ratio of image quality rate and image efficient image. Results Internal iliac artery angiography: image quality rate and image efficient image of carbon dioxide less iodine. Uterine artery angiography: image efficient image of carbon dioxide less iodine. image quality rate of carbon dioxide better than iodine. Conclusion carbon dioxide used as contrast agents in the use of pelvic blood vessels are safe , the obtained image quality is satisfactory , fully meet the diagnostic requirements, have greater promotion of clinical value.
