In an abnormal technetium heart scan, hot spots reveal damage to the heart. The larger the hot spots, the poorer the patient's prognosis.
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.
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.
does myocardial perfusion scan show blockage in heart system.
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.
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.
If the technetium heart scan is normal, no technetium will show up in the heart.
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.
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.
Two to three hours before the scan, technetium is injected into a vein in the patient's forearm.
This scan is used for the diagnostic of heart diseases.
Pregnant women and those who are breastfeeding should not be exposed to technetium.
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.
Cold spots on the scan, where no thallium shows up, indicate areas of the heart that are not getting an adequate supply of blood. Cold spots appearing both at rest and during exercise may indicate areas where the heart tissue.
The patient can resume normal activities immediately after the test.
GES scan studies that show emptying of the stomach in a longer than accepted period is abnormal. Severity of test results and symptoms do not always match; therefore, the physician must carefully interpret these findings. Diabetic.
An abnormal indium scan of the body may show increased uptake in certain areas, suggesting inflammation, infection, or tumor presence. It can also reveal decreased or absent uptake, indicating reduced blood flow or damaged tissue in that area. Additionally, abnormal distribution patterns of the radioactive tracer can signal underlying pathologies such as abscesses or arthritis.
An abnormal liver scan may result from a mass. Depending on the radioisotope and technique used, the scan may identify particular types of tumors or certain cancers.
