Diagnosing Osteoporosis: Bone Densitometry (Bone Mineral Test)

Bone density is measured to assess the risk of developing osteoporosis. It is measured by DXA. DXA gives accurate results. Bone Mineral Density is calculated and compared to normal values to assess the risk factors.

What is bone densitometry

Bone densitometry, using an advanced technology called DXA (Dual-energy X-ray Absorption), is a procedure that accurately and painlessly measures bone density and the mineral content of bone.  This helps in determining a woman's risk of developing osteoporosis.
 

How does the bone densitometry work

Most common examination sites are the fracture-prone hip, spine and sometimes the forearm.  Evaluation also includes measurement of height and weight, a thorough  and risk assessment.  Bone Mineral Density (BMD) is calculated and compared to normal BMD values, matched for age and sex to confirm or rule out osteoporosis.  A low BMD by DXA may predict the likelihood of developing osteoporosis and can help determine a treatment plan.
 

How is it performed

During a comprehensive bone evaluation with DXA, the patient lies comfortably still on a padded table while the DXA unit scans one or more areas, usually the fracture-prone spine or the hip.  Unlike typical x-ray machines, radiation exposure during bone densitometry is extremely low - less than the radiation exposure during a coast-to-coast airline flight.  The entire process takes only minutes to complete, depending on the number of sites scanned.  It involves no injections or invasive procedures, and the patient remains fully clothed.
 

Is any special preparation required before taking the test

  • Unless instructed otherwise by the clinician, eat normally on the day of the exam; but avoid taking any calcium supplements for at least 24 hours prior to the appointment. 
  • Wear loose, comfortable clothing.  Sweat suits and other casual attire without zippers, buttons, grommets or any other metal are preferred.
  • You should not have had a barium study, radioisotope injection, oral or intravenous contrast material from a CT scan or MRI within seven days prior to your DXA test.

in 2003 i developed poly myalgia, a disorder of the muscles and given a high dosis of prednisone. 30 mg per day. reduced this ti 5mg per day after 2 years. this medication has taken the calcium out of my bones and have now a new problem: osteoporosis. i do take now a heavy daily dosis of calcium tablets with 5mg of prednisone every 3 days for the poly myalgia. trying to do away with the prednisone all together.

there should be a qualitative balance between diet,activities and isotonic exerises depending on the age and the exogenous as well as endogenous factors involved.a generalised comment of importance is that milkin excess should be avoided as besides calcium it contains other unhealthy disease inducing factors

alot of people are not into drinking milk as often as we should i'm actually one of them, but we need to realize that we need milk to get the calcium we need to avoid this disease.

i had never heard of osteroporosis before? i think every women should drink enough milk to build the calcium content in her body to fight against such harmful diseases.
