A DEXA scan is an unique sort of X-ray that gauges bone mineral density and the risk of bone weakening.
DEXA means “Dual-energy X-ray absorptiometry”. DEXA or DXA for short.
There’s a confusing proliferation of names for this diagnostic service including:
- DXA check
- bone densitometry
- bone thickness test
DEXA scans are usually made use of to detect or analyze a person’s danger of a weakening of the bones.
Faster and painless, a DEXA scans are also better than X-rays in determining reduced bone mineral thickness.
Weakening of bones
You might should have a DEXA check if you’re:
- over 50 years old with a danger of establishing weakening of bones
- under 50 with various other threat elements– such as smoking cigarettes or a previous bone fracture or break
Whilst weaking of bones can affect everyone older, post-menopausal ladies are specifically in danger. This is since after the menopause the degree of oestrogen decreases, leading to a reduction in bone mineral thickness (BMD).
A DEXA scan can be used to check for bone weakening before a crack or fracture occurs.
Are DEXA scans safe?
DEXA scans use a lot less radiation than convention X-ray exams. In fact the radiation is so low than the technician will normally stay in the room with you during the examination.
Even with such low radiation levels DEXA scans are usually not recommended for expectant mothers.
