Renogram (Renal Flow/Function/Imaging) with Captopril
You have been scheduled for a Renal Study with Captopril which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.

You will be positioned next to a special detector called a gamma camera (see photo). The camera does not produce any radiation. It will be placed close to the part of your body being imaged.

Patient Preparation
Hydrate before injection. Do not take blood pressure medications on the day of the exam.

Procedure
An intravenous line will be put into your arm and you will be hydrated for 30-60 minutes. After 1 hour you will be given Captopril by mouth (blood pressure medication) and your blood pressure will be monitored for one hour. A small amount of radioactive material will be injected into a vein in your arm. Painless images will be obtained for approximately 60 minutes.
