What is a SPECT Scan?

A SPECT scan is a nuclear imaging test. It checks blood flow and activity in the brain. This makes it great for diagnosing neurological and psychiatric conditions.
Definition and Basic Principles
A SPECT scan uses a tiny amount of radioactive tracer. This tracer is injected into the blood. It emits gamma rays that the scanner picks up.
The scanner then makes detailed, 3D images of the brain’s blood flow and activity. Areas with more activity have more blood flow and tracer. This helps understand brain function and find problems.
Key aspects of SPECT scan principles include:
- Use of radioactive tracers to visualize brain activity
- Detection of gamma rays emitted by the tracer
- Creation of 3D images representing brain blood flow and activity
How SPECT Differs from Other Imaging Techniques
