Angiography

angiogramarteriographyangiographic
The advantage of a MUGA scan over an echocardiogram or an angiogram is its accuracy.
The term angiography has been applied to radionuclide angiography and newer vascular imaging techniques such as CT angiography and MR angiography.

Radiopharmaceutical

It involves use of a radiopharmaceutical, injected into a patient, and a gamma camera for acquisition.

Trastuzumab

herceptin Trastuzumab/HerceptinHercpetin
Who are undergoing cardiotoxic drug agents such as in chemotherapy e.g., with doxorubicin or immunotherapy (herceptin)
As a result, regular cardiac screening with either a MUGA scan or echocardiography is commonly undertaken during the trastuzumab treatment period.

Pertechnetate

[ 99m TcO 4 pertechnatepertechnetate ion
The MUGA scan is performed by labeling the patient's red blood pool with a radioactive tracer, technetium-99m-pertechnetate (Tc-99m), and measuring radioactivity over the anterior chest as the radioactive blood flows through the large vessels and the heart chambers.
It is also used in labeling of autologus red blood cells for MUGA scans to evaluate left ventricular cardiac function, localization of gastrointestinal bleeding prior to embolization or surgical management, and in damaged red blood cells to detect ectopic splenic tissue.

Ejection fraction

left ventricular ejection fractionejectedinjection fraction
Mathematics regarding acquisition of cardiac output (Q) is well served by both of these methods as well as other inexpensive models supporting ejection fraction as a product of the heart/myocardium in systole.
Ejection fraction is commonly measured by echocardiography, although cardiac magnetic resonance imaging (MRI), cardiac computed tomography, ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) scans may also be used.

Tin(II) chloride

stannous chlorideSnCl 2 tin chloride
In the in vitro method, some of the patient's blood is drawn and the stannous ions (in the form of stannous chloride) are injected into the drawn blood.
SnCl 2 is used in radionuclide angiography to reduce the radioactive agent technetium-99m-pertechnetate to assist in binding to blood cells.
