Gamma or Nuclear Medicine scans are special imaging tests that show how your organs and tissues are working, not just what they look like. These scans use a tiny, safe amount of radioactive material called a tracer. Once the tracer enters your body—either by injection, swallowing, or inhaling—it travels to the organ being studied. A gamma camera then takes pictures, showing how that part of your body is functioning.
These scans are very sensitive and can detect disease much earlier than regular scans like CT or MRI. That makes them especially useful for early diagnosis and treatment planning.
Why are they done?
In cardiology, they check heart blood flow and muscle health (like after a heart attack).
For bones and joints, they detect infections, fractures, or cancer spread.
In neurology, they help diagnose conditions like Parkinson’s, memory loss, or epilepsy.
Endocrinology uses them for thyroid or parathyroid problems.
In oncology, they locate tumours, track cancer spread, and assess treatment response.
Lung scans can detect blood clots or infections.
Kidney and liver scans evaluate function or look for blockages and leaks.
What happens during the scan?
You may need to wait while the tracer reaches the target organ. The scan itself is painless. You’ll lie still while the camera captures images. Depending on the scan, it may take 30 minutes to a few hours.
Before and after the scan:
Follow any fasting or prep instructions given. Inform your doctor if you are pregnant or breastfeeding. After the scan, drink plenty of water to flush out the tracer, and avoid close contact with young children or pregnant women for a few hours if advised.
Why choose this scan?
It’s safe, minimally invasive, and gives crucial insights into your health—often before symptoms appear
