What Is SPECT?
SPECT is an acronym of Single Photon Emission Computed
Tomography.
A SPECT is a scanner for medical purposes where it is a type of
nuclear imaging test. It uses radioactive substance and special camera
to crate 3-D pictures.
A SPECT scanner works similar as X-Ray. However SPECT scanner is
not only used to see bones but the organs inside our body. For
example to see the blood flows in veins, brain, etc.
How Does it Work?
Before a person gets into the machine, he/ she is
injected with a chemical that is radiolabeled to emit
gamma rays that can be detected by the scanner.
The computer will take the emitted images of the gamma
rays in 2-D and translate it into 3-D images.
What Substances are used in this machine?
The radioisotopes that is used here are iodine-123,
technetium- 99m, xenon-133, thallium-201, and fluorine-
18.
These radioactive are safe to use and will not harm our
body once the scanner is detecting.
These radioisotopes also be able to spot other drugs
and chemicals inside our body.
What Does this DO?
This machine can detect brain disorders such as
Dementia
Clogged blood vessels
Epilepsy
Heart Problem
Clogged coronary arteries
Reduced pumping efficiency
Bone disorders
What are the Side Effects?
This machine is really safe to use.
There are may several things happened after the
scanning such as;
Bleeding, pain during the injection
Allergic but it is really rare happening.
