Dual Energy X-ray Absorptiometry (Dexa scan)
A dexa scan is used specifically to assess a patients
risk of fracture by detecting osteoporosis of the vertebral
bodies, which is a thinning of the bones as we age.
A dexa scan takes about ten minutes and is associated
with minimal radiation exposure.
Low energy x-rays are passed through the bones to measure
the mineral (calcium) content of the bones. If the patient
is osteoporotic and has a significant risk of fracturing
a vertebral body, osteoporosis medications can be prescribed
to reduce their risk.
