What is a Bone Density Scan?
Why it's done
- Determine your risk of broken bones (fractures)
- Confirm a diagnosis of osteoporosis
- Monitor osteoporosis treatment
- Lost Height : People who have lost at least 1.6 inches (4 centimeters) in height may have compression fractures in their spines, for which osteoporosis is one of the main causes.
- Fractured a Bone : Fragility fractures occur when a bone becomes so fragile that it breaks much more easily than expected. Fragility fractures can sometimes be caused by a strong cough or sneeze.
- Taken Certain Drugs : Long-term use of steroid medications, such as prednisone, interferes with the bone-rebuilding process — which can lead to osteoporosis.
- Received a Transplant. : People who have received an organ or bone marrow transplant are at higher risk of osteoporosis, partly because anti-rejection drugs also interfere with the bone-rebuilding process.
- Had a Drop in Hormone Levelss : In addition to the natural drop in hormones that occurs after menopause, women's estrogen may also drop during certain cancer treatments. Some treatments for prostate cancer reduce testosterone levels in men. Lowered sex hormone levels weaken bone.
Staying ahead of Osteoporosis
Osteoporosis doesn’t usually produce symptoms until a fracture occurs—most typically in the hip, back, or wrist. Collapsed vertebrae due to osteoporosis can result in severe back pain, loss of height, and a stooped posture or other spinal deformities. It is also estimated that this disease is responsible for 1.3 million fractures a year.
Postmenopausal women at special risk
Women who have gone through menopause are at greatest risk for osteoporosis. Due to hormonal changes, women can lose up to 20 percent of their total bone mass in just the five to seven years following menopause. Although osteoporosis occurs more commonly in women, men can also be at risk, especially if they are inactive, and as they get older
Benefits of a Bone Density Scan
A bone density test is the only test that can diagnose osteoporosis before a broken bone occurs. This test helps to estimate the density of your bones and your chance of breaking a bone. NOF recommends a bone density test of the hip and spine by a central DXA machine to diagnose osteoporosis.
Preparation
No Calcium or vitamins for 24 hours prior to exam
Risks of a Bone Density Scan
Risks of a Bone Mineral Density Test. Because a bone mineral density test uses X-rays, there is a small risk associated with radiation exposure. However, the radiation levels are very low. Experts agree that the risk posed by this radiation exposure is far lower than the risk of not detecting osteoporosis before you get a bone fracture.
