SPECT (Single Photon Emission Computed Tomography) is a nuclear imaging test that uses radioactive substances and a special camera to create 3D pictures of organs inside the body. It can detect issues like brain disorders, heart problems, and bone disorders. During a SPECT scan, a person is injected with a radioactive substance like iodine-123 or technetium-99m that emits gamma rays. A scanner then detects these gamma rays and uses the images to create 3D pictures of the area being examined. The radioactive substances used are generally safe and will clear from the body after the scan is complete.

2. 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.

3. 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.

4. 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.

5. 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

6. 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.
