What is the purpose of a MUGA scan?
What is the purpose of a MUGA scan?
What is a MUGA scan? A multigated acquisition scan (also called equilibrium radionuclide angiogram or blood pool scan) is a noninvasive diagnostic test used to evaluate the pumping function of the ventricles (lower chambers of the heart). During the test, a small amount of radioactive tracer is injected into a vein.
What is a MUGA scan and how is it done?
During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer-generated movie images of the beating heart. The MUGA scan is a highly accurate test used to determine the heart’s pumping function.
What is the difference between MUGA scan and echocardiogram?
But how each test generates images is fundamentally different: A MUGA scan is a nuclear medicine test that uses gamma rays and a chemical tracer to generate images of your heart. An echocardiogram uses high-frequency sound waves and a transducer with a special gel to generate ultrasound images of your heart.
How long does it take to do a MUGA scan?
A MUGA scan takes about an hour. First a technologist will place an IV in a vein in your arm and draw 3-5ml’s of blood. The technologist will then attach a radioactive isotope to your red blood cells. This process usually takes about 15-20 minutes.
Can I eat before a MUGA scan?
Getting ready for a MUGA scan When you schedule the scan, you will receive detailed instructions on how to prepare. What to eat. You may not be able to eat or drink for 4 to 6 hours before the test. You may also be asked to avoid caffeine and tobacco for up to 24 hours before the test.
Is MUGA scan safe?
The MUGA scan is considered a safe test and the risks are generally low. The heart has 4 chambers: 2 atria and 2 ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
What happens if your ejection fraction is low?
Low ejection fraction causes Cardiomyopathy, which causes your heart muscle to become enlarged, thick or stiff. Coronary artery disease, where plaque builds up in the two main arteries that supply blood to your heart and blocks blood flow. Heart attack, when blood flow to your heart muscle became blocked and damaged it.
How do you strengthen a weak heart muscle?
7 powerful ways you can strengthen your heart

- Quit smoking. Quitting smoking is tough.
- Lose weight. Losing weight is more than just diet and exercise.
- Eat heart-healthy foods.
- Don’t forget the chocolate.
- Don’t overeat.
- Don’t stress.
What do you need to know about a MUGA scan?
As the blood fills the ventricles or chambers of the heart, the camera picks up a clear picture of the heart’s function, creating an animated image of the beating heart which is used in diagnostics. A MUGA scan may be performed on a patient who recently had a cardiac event. There are some variations on the basic MUGA scan.
What does Muga stand for in medical terms?
MUGA Scan. It shows any abnormalities in the size of the chambers (called “ventricles”) and in the movement of blood through the heart. Other names for this test include cardiac blood pooling imaging, nuclear heart scan, nuclear ventriculography, and radionuclide ventriculography.
Where does technetium 99 go during a MUGA scan?
If you are having a MUGA scan, a tiny amount of Technetium 99 (a radioactive substance) is injected into your bloodstream. The Technetium 99 attaches to your red blood cells, and circulates within your bloodstream.
When to eat and drink before a MUGA scan?
You may not be able to eat or drink for 4 to 6 hours before the test. You may also be asked to avoid caffeine and tobacco for up to 24 hours before the test. Topics to discuss. Be prepared to discuss the following topics with your health care team:
What is a Persantine MIBI scan?
A Persantine MIBI scan is a procedure that is performed to evaluate individuals with suspected cardiovascular disease . Special imaging is performed that detects MIBI as it distributes throughout the heart tissue. The images allow the clinician to observe any areas of abnormal blood flow in the heart, which may indicate coronary artery disease.
What does Muga mean?
Definition of muga in English: muga. noun. A wild silk obtained in Assam from the cocoons of the silkworm Antheraea assama (also ” muga silk “); the silkworm itself (also “muga silkworm”).
How do you check your heart function?
To best check your heart rate, place two fingers on your wrist, on the inside of your elbow, on the side of your neck or on the top of your foot. Once you find your heart rate simply count how many beats you feel within 60 seconds.
What are the different types of heart tests?
Tests that may be used to diagnose heart conditions or the risk of developing heart conditions include blood tests, exercise stress testing, EKG, X-Ray, and imaging tests, such as heart scan, ultrasound and echocardiogram. A coronary angiogram may be dome in certain cases.
