What characteristics does a normal technetium heart scan have?
If the technetium heart scan is normal, no technetium will show up in the heart.
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 does technetium 99m exist as?
Technetium-99m exists as a metastable isomer, meaning it is in a higher energy state but has a relatively long half-life compared to other technetium isotopes. It decays by emitting gamma radiation, making it useful for medical imaging procedures.
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 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 is cpt code for sestamibi parathyroid study?
sestamibi
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 is the purpose of a technetium heart scan?
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.
When would you use technetium in a nuclear medicine thyroid scan?
If I-123 was not available and that is the only reason ever. Some places use Tc99m because it is cheaper and faster than I-123. But i-123 was developed because it was and is better than straight Tc99m
What kind of rays emitted in nuclear scan?
It depends on the type of scan but by far the most common scan uses "gamma" rays to get a picture. The radionuclide used is Tc99m which gives off gamma rays at 140 kEV, a very suitable energy level for the cameras used in nuclear medicine.
What care should a patient receive after a technetium heart scan?
The patient can resume normal activities immediately after the test.
