What is a PET-CT Scan?
A PET-CT Scan is an advanced medical imaging test that combines two technologies:
- PET (Positron Emission Tomography) – shows how organs and tissues are functioning.
- CT (Computed Tomography) – provides detailed images of the body’s internal structure.
Together, PET-CT helps doctors detect diseases more accurately by showing both the structure and activity of tissues and organs in a single scan.
Why is a PET-CT Scan Done?
PET-CT scans are commonly used to:
- Detect and diagnose cancer
- Monitor cancer treatment progress
- Identify heart problems
- Evaluate brain disorders
- Detect infections or inflammation
- Check the spread of diseases in the body
How Does the Scan Work?
Before the scan, a small amount of radioactive tracer is injected into the body. This tracer highlights areas of abnormal activity. The PET scan detects this activity, while the CT scan creates detailed images of the body.
The combined images help doctors identify health conditions with greater accuracy.
Is PET-CT Scan Safe?
Yes, PET-CT scans are generally safe when performed by trained professionals. The amount of radiation used is controlled and medically approved. Patients are advised to follow pre-scan instructions provided by the healthcare team.
How Long Does the Procedure Take?
A PET-CT scan usually takes between 30 minutes to 2 hours, depending on the type of examination and preparation required.
