Whole skeleton at once
A small tracer dose circulates and settles where bone turnover is high; a gamma camera then surveys the entire skeleton in one study.
Diagnostics · Standard
Bone Scintigraphy
A nuclear-medicine bone scan that can highlight areas of increased bone activity across the skeleton.
What it is
A survey of the whole skeleton
When pain could come from several places — or when MRI shows changes of unclear age — bone scintigraphy steps back to see everything. A tracer highlights metabolically active bone, and the pattern of hot and cold spots directs the focused imaging that follows.
Hot spots explained
Bright areas mark healing fractures, infection, arthritis, tumours or recent surgery — anywhere active remodelling is under way.
Sensitive, not specific
The scan finds almost everything active but names nothing. Every hot spot is correlated with MRI, CT and your symptoms before it means anything.
Silent areas matter too
Cold spots with reduced uptake can flag dead bone or certain lesions — absence of activity is information as well.
Common questions
Things patients ask us
Does a hot spot mean cancer?
No. The overwhelming majority of hot spots are benign — healing fractures, arthritis and infection glow just as brightly. Further work-up decides what each one is.
Is the tracer safe?
The radioactive tracer dose is small and passes naturally. Tell the team if you are pregnant, breastfeeding, or recently had contrast or nuclear-medicine studies.
Why scan the whole body for back pain?
Because pain can originate far from where it is felt — and because ruling the rest of the skeleton out narrows the search honestly.
How should I prepare?
Follow the instructions you are given. Drinking water beforehand is commonly advised unless you are told otherwise.
