Your doctor has ordered a renal scan. The role of this procedure is to evaluate kidney function and perfusion, kidney failure, kidney obstruction and to follow up on kidney transplants. Renal scans may also be used to screen and diagnose renovascular hypertensive disease. Our team of specialized doctors, nurses and technologists is led by Alan Waxman, MD, Chief of Nuclear Medicine.
Before Arriving for Your Exam
Drink two 8-ounce glasses of fluids 1-2 hours prior to the exam.
If your test is scheduled to diagnose renovascular hypertension, you should be off ACE inhibitor medications for at least 48 hours. You must consult with your physician before discontinuing your medications.
We want to make your waiting time as pleasant as possible. Consider bringing your favorite magazine, book or music player to help you pass the time.
Please leave your jewelry and valuables at home.
Upon arrival, a technologist will explain your procedure and answer any questions you may have.
During Your Exam
Once in the exam room, you will be asked to lie flat on your back on the imaging table.
You will receive an intravenous injection (in your vein) of a tracer dose of radioactive material. The level of radioactivity is extremely low and has no side effects.
If your test is scheduled to diagnose renovascular hypertension, you will receive a pill (captopril) to swallow, and will have your blood pressure monitored every 15 minutes for possibly 1 hour before the injection of radioactive material.
Using a special nuclear medicine camera, pictures of your kidneys will be obtained over the course of approximately 1 hour. The camera does not produce any radiation; it simply detects and records the distribution of the radioactive material in your kidneys.
After Your Exam
Your study will be reviewed by an imaging physician specialist and the results sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
