Description
Prostate-Specific Membrane Antigen (PSMA) PET Scan is an advanced and highly sensitive imaging technique used in the diagnosis and management of prostate cancer. It works by detecting PSMA, a protein that is found in much higher amounts on prostate cancer cells than on normal tissues.
By targeting this protein, the PSMA PET scan allows doctors to locate even very small areas of prostate cancer that may not be visible on conventional CT, MRI, or bone scans.
What Is a PSMA PET Scan?
A PSMA PET scan is a type of Positron Emission Tomography that uses a special radioactive tracer designed to bind specifically to PSMA proteins on prostate cancer cells. Once injected, this tracer travels through the body and attaches to cancerous tissue, allowing it to be clearly seen on PET imaging.
Why Is a PSMA PET Scan Performed?
This scan is commonly used to:
- Detect prostate cancer at an early stage
- Locate the spread of cancer to lymph nodes or bones
- Evaluate rising PSA levels after treatment
- Guide radiation or surgical treatment planning
- Monitor response to therapy
How Is a PSMA PET Scan Done?
A small amount of PSMA-targeted radiotracer is injected into a vein. After allowing time for the tracer to bind to PSMA-expressing cells, the patient lies on the PET scanner while images are taken.
The scan is painless and usually completed within 30 to 60 minutes.
Benefits of PSMA PET Imaging
- Extremely accurate detection of prostate cancer
- Identifies very small or early metastases
- Improves treatment planning and outcomes
- Non-invasive and safe
Book a PSMA PET Scan
If you have prostate cancer or rising PSA levels, a PSMA PET Scan provides the most precise imaging available to help guide diagnosis and treatment decisions.
