Kidney angiogram. Coloured angiogram X-ray showing the blood supply within a healthy kidney. The renal artery is seen entering the kidney from the right (yellow). The renal arteries branch off the aorta (not seen),the main artery leading from the heart. The kidneys serve to filter waste products from the blood,and excrete them as urine. Spinal vertebrae (yellow) are visible at right. Angiograms are produced by taking an X-ray after injecting the patient with a contrast medium (a substance opaque to X-rays). Here,a catheter has been used to add the medium. It can be seen in front of the vertebrae at lower right. Angiograms are used to diagnose blood vessel disorders | |
