Radionuclide Ventriculography or Radionuclide Angiography (MUGA Scan) - 1 views

  • For example, an ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle when it is full is pumped out with each heartbeat. A normal ejection fraction is between 50 and 75 percent.
  • Chest pain (angina)Trouble breathingDizzinessTiredness
  • Your heart may not be pumping enough blood to meet your body’s needs. This is called heart failure.

  • Your body will get rid of it through your kidneys within about 24 hours.
  • The disks have wires that hook to an electrocardiograph machine to record your ECG. The ECG tracks your heartbeat during the test. 
  • For an “exercise” scan, will generally walk on a treadmill or ride a stationary bicycle until you reach your peak activity level.
  • In some labs you may lie on a table and pedal a specially mounted bicycle

MUGA Scan | Cancer.Net - 1 views

  • cardiac blood pooling imaging, nuclear heart scan, nuclear ventriculography, and radionuclide ventriculography.
  • Some people with cancer who receive chemotherapy or other drugs may need this test before cancer treatment to identify preexisting heart conditions or during or after cancer treatment to identify chemotherapy-related heart damage.
  • side effects that occur more than five years after treatment
  • ...18 more annotations...
  • chemotherapy, such as anthracyclines, may damage the heart during cancer treatment.
  • heart damage from these drugs can cause congestive heart failure (CHF; a condition in which the heart does not pump enough blood to the rest of the body)
  • arrhythmia (an irregular heartbeat)
  • heart damage is mild and is only detected on MUGA scans
  • performed by a nuclear medicine technologist who has been specially trained and certified to conduct the test
  • The technologist is supervised by a radiologist (a medical doctor who specializes in using imaging tests to diagnose disease) or a nuclear medicine physician. The scan results are interpreted by a radiologist.
  • place stickers called electrodes on your chest to monitor your heart’s electrical activity during the test and inject a small amount of a radioactive material, called a tracer, into a vein in your arm. Sometimes the test is done by withdrawing a small amount of blood from your arm, mixing it with the tracer, and then putting that mixture back into your body through an IV (a tiny plastic tube inserted directly into a vein).
  • The radioactive material is like a dye, and it binds to your red blood cells (cells that carry oxygen throughout your body), making it easier to see how blood moves through your heart.
  • special camera—which is about three feet wide and uses gamma rays to track the tracer—above your chest.
  • nitroglycerin (multiple brand names; a drug that opens your blood vessels) during the test to see how your heart responds to the medication.
  • two to three hours to complete
  • ejection fraction (the amount of blood pumped out of the ventricles).
  • A result of 50% or higher is considered normal, meaning that your heart is efficiently pumping blood throughout your body
  • an abnormal result may mean you have a blockage in an artery, poor pumping function, heart valve disease, or other disorder.
  • switch treatments or give you a different type of chemotherapy.

  • What will happen if I don’t have this procedure?
  • What will happen during the procedure?

Nuclear ventriculography: MedlinePlus Medical Encyclopedia - 1 views

  • radioactive materials called tracers to show the heart chambers.
  • The instruments do not directly touch the heart.
  • resting.

  • technetium into your vein
  • substance attaches to red blood cells and passes through the heart.
  • Special cameras or scanners trace the substance as it moves through the heart area. The red blood cells inside the heart that carry the radioactive material form an image that the camera sees. The camera is synchronized with an electrocardiogram. Using computer software, the images are made to appear as if the heart is moving.
  • The test will show how well the blood is pumping through different parts of the heart.
  • The test also can check the motion of different parts of the heart. If one part of the heart is moving poorly while the others move well, it may mean that there has been damage to that part of the heart, possibly from a blockage in the artery that delivers blood to that area.
