A radionuclide ventriculogram (RVG) is a special type of x-ray used to look at how well the heart works. Certain chemotherapy drugs can be harmful to the heart and if the results of this test are outside normal limits, the doctor may change the dose or the type of chemotherapy.
The Procedure - What to Expect
A blood sample will be taken prior to the test, either through your Hickman® line or from your arm if you don't have a line. Then a small amount of radioactive material is mixed with the blood specimen and injected into a vein with a small needle.
You will be asked to lie still as the machine traces the path of the injected blood on a monitor screen. From the pictures taken, the doctor can see how well the heart pumps blood and how well the heart valves work.
Since the amount of radiation used to tag the blood is tiny and doesn’t last long, your exposure to radiation is also very small. This procedure takes between 1-2 hours.
