Renal Artery Stenosis
Your doctor has requested an ultrasound of the renal arteries that supply your kidneys with blood. Ultrasound technology is safe and images arteries and veins. There is no radiation or injection of chemicals. This procedure is performed to evaluate your femoral artery for possible injury, aneurysm or blood clot.
At the Cedars-Sinai S. Mark Taper Foundation Imaging Center, we have a specialized team of physicians and technologists who are experts in ultrasound technology.
Before Your Exam
- Please do not eat or drink six hours before your exam. You may take any scheduled medication with a sip of water.
- If your doctor gave you an order, please bring it with you.

During Your Exam

- You will be lying on the exam table on your back with your hands at your sides. The technologist will apply a warm gel to your abdomen and a transducer or a small microphone will be used to examine your arteries.
- You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. The exam will take approximately 60 minutes.
After Your Exam
