Renogram Exam

A nuclear medicine renogram provides your doctor with information that measures the kidney blood flow and function.

Exam preparation

A CDI representative will call you prior to your appointment to provide specific instructions, and review health and insurance information.
Please bring previous imaging study results (x-ray, MRI, CT, etc.) such as reports, films or CD-roms if available.
Notify a member of CDI’s staff if you are nursing or if there is a chance you could be pregnant.
Please arrive 15 minutes early to verify your registration and health information.

During the exam – what to expect

You will lie down on a scanning table and receive an I.V. in your arm or hand.
A radioactive agent is injected into your vein (this is not a dye or contrast and there are no side affects)
The substance is collected in the kidneys and washes out into your bladder.
A camera will collect images for 30-60 minutes.
While the images are being obtained, you must remain as still as possible.

After the exam – what to expect

A radiologist who specializes in a specific area of the body reviews your images (i.e., a body radiologist will review the images of your kidney).
The radiologist prepares a diagnostic report to share with your doctor.
Your doctor will consider this information in context of your overall care, and talk with you about the results.
Most of the radioactivity passes out of your body within 24 hours.
