MUGA scan

A multigated acquisition (MUGA) scan is an imaging examination used to assess how well your heart pumps blood. It employs a radionuclide injection as well as a customized camera. Your healthcare practitioner takes photos of your heart as the radionuclide goes through your blood.

A MUGA scan detects how your heart muscle contracts and relaxes during rest or exercise. MUGA scans are also known as radionuclide ventriculography (RNVG) and equilibrium radionuclide angiocardiography (ERNA).

What are the uses of MUGA scans?

If you show indicators of heart failure, your doctor may recommend a MUGA scan. Your heart does not pump blood as effectively as it should when you have heart failure. The following are some of the most prevalent symptoms of heart failure:

A MUGA scan may be ordered by your doctor before or after cancer treatment. Cancer therapies have caused cardiac damage in certain people, including:

What happens during a MUGA scan?

During this test, you will be asked to lie still on an exam table while a special camera is positioned over your chest.

  • Electrodes that assess cardiac activity are attached to your chest.
  • The radiotracer is injected into your vein.
  • Pictures from a variety of angles will be taken.
  • The technician wants you to exercise between images, such as walking on a treadmill. Exercise allows your cardiologist (heart doctor) to monitor your stress levels.

How to prepare for a MUGA scan?

To prepare for a MUGA scan, your clinician will provide you with tailored advice. In general, you should refrain from eating or drinking anything for up to six hours before the test. Your physician may also advise you to abstain from caffeine for a period of time. Coffee might cause your heart rate to increase, which can interfere with test findings. Inform your doctor about all of the drugs you are taking.

What are the risks associated with a MUGA scan?

Most people are not at risk from MUGA scans. The radiotracer isn't dangerous, and it normally passes through your body within 24 hours.

Inform your doctor if you are pregnant, suspect you are pregnant or are breastfeeding. These tests are normally not recommended for pregnant or breastfeeding women since they may cause harm to the baby.

Understanding MUGA scan results

The results of a MUGA scan can provide information about the overall function of the heart and how well it is able to pump blood.

The results of a MUGA scan are typically reported in terms of the ejection fraction (EF), which is a measure of how much blood the left ventricle is able to pump out with each heartbeat. A normal EF is typically between 50% and 70%.

If the EF is lower than normal, it may indicate that the heart is not functioning properly and may be a sign of a heart condition. Depending on the specific findings of the MUGA scan, further testing or treatment may be recommended.

It is important to discuss the results of a MUGA scan with your healthcare provider, who can provide more specific information based on your individual circumstances and medical history.

Frequently Asked Questions

1. What is a MUGA scan?

A MUGA scan is an imaging test that uses a small amount of radioactive material and a special camera to create images of the heart as it beats. It is often used to assess the function of the heart's ventricles.

2. Why is a MUGA scan done?

A MUGA scan is typically done to evaluate the function of the heart and how well it is able to pump blood. It might be done to diagnose or monitor heart conditions such as heart failure, cardiomyopathy, or coronary artery disease.

3. How is a MUGA scan performed?

During a MUGA scan, a small amount of radioactive material is injected into the arm veins. The material then travels to the heart, where it emits radiation that is detected by a special camera. The camera creates images of the heart as it beats, which can be analyzed to assess the function of the ventricles.

4. Is a MUGA scan safe?

MUGA scans are generally considered safe, although there is a small amount of radiation exposure involved. The level of radiation exposure is usually considered low and not harmful. However, pregnant or breastfeeding women should let their healthcare provider know before having a MUGA scan.

5. How long does a MUGA scan take?

A MUGA scan typically takes about 30-60 minutes to complete. However, the exact duration may vary depending on the specific protocol used by the healthcare provider.

6. Can I take a MUGA scan on an empty stomach?

In general, you may be asked to avoid eating or drinking anything for some hours before the test.

7. How to prepare for a MUGA scan?

You may be asked to avoid caffeine or certain medications before the scan. Your healthcare provider will provide specific instructions on how to prepare for the test.

8. Does a MUGA scan detect heart failure?

Yes, a MUGA scan detects heart failure.

9. What is the cost of a MUGA scan?

A MUGA scan might cost around Rs. 3000 to Rs. 5000 approximately, however, the price can vary from place to place.

10. Where can I get a MUGA scan?

You can get a MUGA scan at Medicover Hospitals.
