Bone Densitometry
Dexa
Bone Densitometry using GE’s
Lunar Prodigy
State-of-the-art fracture risk and osteoporosis assessment
tool
Osteoporosis is a disease in which
bone density decreases, making bones brittle and prone
to fracture. Osteoporosis
is treatable and preventable. Early diagnosis,
therapeutic intervention and the use of bone density
testing has greatly improved the prognosis for patients.
Osteoporosis affects women after menopause but may also
be found in men.
To detect osteoporosis accurately – it
is an enhanced form of x-ray called dual-energy x-ray
absorptiometry (DEXA) is today’s standard for measuring
bone mineral density (BMD). Dexa is quick, painless – measurement
of the lower spine and hips are most often done.
The scan produces an intense narrow beam of radiation
that quickly and precisely measures bone density.
You will be positioned on an exam table to measure the
bone density and the computer will calculate your score
so that the radiologist can diagnose whether your bones
are showing signs of osteoporosis.
Comprehensive clinical capabilities include advanced
dual Femur analysis, lateral vertebral assessment, hip
axis length, and precise measurement of bone mineral
content.
Bone density testing is strongly recommended
if
- You are a post-menopausal woman and not taking estrogen
- Have a personal or maternal history of hip fracture
or smoking
- Are post-menopausal over 5 ft 7
inches or thin, less than 125lbs
- Are a man with clinical conditions associated with
bone loss
- Use medications known to cause bone loss
- Have type 1 diabetes, liver disease,
kidney disease or
family history of osteoporosis
- Have high bone turnover, excessive collagen in urine
samples
- Have hyperthyroidism
- Have experienced a fracture after only a mild trauma
- Have x-ray evidence of vertebral
fracture or other signs
of osteoporosis
Preparation
- On the day of the exam eat
normally, but don’t
take calcium
supplements for at least 24 hours beforehand.
- Wear loose, comfort clothing, avoiding
garments that have
zippers, belts or metal buttons
- Inform your physician if you recently
had a barium examination,
you may have to wait 10 to
14 days before undergoing an ultrasound.
