What is Renal Artery Ultrasound?
Renal ultrasound is a test which utilizes high frequency sound waves to obtain images of your renal arteries. This test is used to determine if there are any problems with the vessels that supply blood flow to the kidneys. The technologist applies an acoustic gel on your abdomen over the area to be viewed. A painless instrument called a transducer is then gently moved across that portion of your body to visualize the inside of the arteries that carry blood to the kidneys.
