Fig. 7From: Effect of different injection rates and doses of contrast medium on the image quality of computed tomographic angiography in African grey parrots (Psittacus erithacus)Images under different doses of contrast medium. These three images taken at the same axial plane were acquired from the same bird with different doses of contrast medium. From left to right: 740, 370, 222 mg of iodine/bird. It was obvious that with a higher dosage, the attenuation increases, and the diameter increases due to the blooming artifactsBack to article page
