The technetium heart scan is used to evaluate the heart after a heart attack. It can confirm that a patient had a heart attack when the symptoms and pain usually associated with a heart attack were not present; identify the size and location.

What characteristics does an abnormal technetium heart scan have?
In an abnormal technetium heart scan, hot spots reveal damage to the heart. The larger the hot spots, the poorer the patient's prognosis.
What risks exist for the patient in undergoing a technetium heart scan?
The technetium heart scan is not dangerous. The technetium is completely gone from the body within a few days of the test. The scan itself exposes the patient to about the same amount of radiation as a chest x ray.
What is a Myocardial perfusion scan used for?
does myocardial perfusion scan show blockage in heart system.
What is a muga scan used to detect?
The MUGA scan stands for Multiple Gated Acquisition Scan and is an extremely useful tool to assess the function of the heart. It's also noninvasive. The scan provides a moving image of the beating heart. From this image medical professionals can make conclusions about the health of the cardiac ventricles.
How is a gastric emptying scan done?
During the study, patients are asked to ingest an egg sandwich containing a radioactive substance (for example, technetium) that can be followed by a special camera. The emptying of the material from the stomach is then followed.
What characteristics does a normal technetium heart scan have?
If the technetium heart scan is normal, no technetium will show up in the heart.
What characteristics does an abnormal technetium heart scan have?
In an abnormal technetium heart scan, hot spots reveal damage to the heart. The larger the hot spots, the poorer the patient's prognosis.
What risks exist for the patient in undergoing a technetium heart scan?
The technetium heart scan is not dangerous. The technetium is completely gone from the body within a few days of the test. The scan itself exposes the patient to about the same amount of radiation as a chest x ray.
How should patients be prepared for a technetium heart scan?
Two to three hours before the scan, technetium is injected into a vein in the patient's forearm.
What is technetium Tc-99m sestamibi scan?
This scan is used for the diagnostic of heart diseases.
What precautions need to be taken when doing a technetium heart scan?
Pregnant women and those who are breastfeeding should not be exposed to technetium.
How is a technetium heart scan done?
The isotope is injected into a vein and absorbed by healthy tissue at a known rate during a certain time period. The radionuclide detector, in this case a gamma scintillation camera, picks up the gamma rays emitted by the isotope.
What care should a patient receive after a technetium heart scan?
The patient can resume normal activities immediately after the test.
What is the purpose of the MUGA scan?
The MUGA scan is performed to determine if the heart's left and right ventricles are functioning properly and to diagnose abnormalities in the heart wall.
What is the purpose of a thallium heart scan?
The purpose of a thallium heart scan, also known as a thallium stress test or myocardial perfusion scan, is to evaluate the blood flow to the heart muscle. It is used to diagnose coronary artery disease and assess the severity of blockages or narrowing in the coronary arteries. The scan helps determine if there is enough blood supply to the heart during exercise or stress.
What is the purpose of photometric scan?
what is the purpose of photometric scan
What is a mugascan?
The MUGA scan (MUltiple Gated Acquisition scan) is an extremely useful noninvasive tool for assessing the function of the heart. The MUGA scan produces a moving image of the beating heart, and from this image several important features can be determined about the health of the cardiac ventricles (the heart's major pumping chambers).How is the MUGA scan performed?A MUGA scan is performed by attaching a radioactive substance, Technetium 99, to red blood cells, then injecting the red blood cells into the patient's bloodstream. The patient is then placed under a special camera (a gamma camera), which is able to detect the low-level radiation being given off by the Technetium-labelled red cells. Since the red blood cells (including those that are radio-labelled) fill the cardiac chambers, the image produced by the gamma camera is essentially an outline of those chambers. With some fancy computer manipulation, the the final product is a movie of the heart beating.
