bone densitometry

(redirected from bone density scan)

bone densitometry

The measurement of bone mass or density. The current methods—single-photon absorptiometry, dual-energy photon absorptiometry, dual-energy X-ray absorptiometry—are based on tissue absorption of photons derived from either a radionuclide or an X-ray tube; the latter are more accurate with shorter scan time. Other techniques are based on ultrasonography.

bone min·er·al den·si·ty

(BMD) (bōn min'ĕr-al den'si-tē)
Measurement of the amount of calcium in bone. Most methods for measuring BMD (also called bone densitometry) are fast, noninvasive, painless, and available on an outpatient basis. Bone densitometry can also be used to estimate a patient's risk of fracture. BMD methods involve taking dual energy x-rays (DEXA) or CT scans of bones in the spinal column, wrist, arm, or leg. These methods compare the numeric density of the bone (calculated from the image) with empiric (historical) databases of bone density to determine whether a patient has osteoporosis, and to what degree.
Synonym(s): bone densitometry.

The two biggest risk factors for osteoporosis are gender and age, so women over the age of 65 should have a bone density scan. Women under 65 who have other risk factors should be tested earlier to establish a baseline bone density.
Anthea, who rose to fame presenting Top Of The Pops in the Eighties and hosted Blue Peter for two years in the Nineties, found out following a bone density scan that she had osteopenia in her spine and hip bones.
The DeM General Secretary, Nahida Nasreen in a statement in Srinagar said that Aasiya Andrabi was taken to hospital for a magnetic resonance imaging (MRI) and bone density scan. 'As Aasiya Andrabi is an asthma patient she wasn't able to go through the closed MRI procedure and felt suffocated inside the facility and had to be taken out immediately,' she added.
Women aged 65 and older and men aged 70 and older should get a bone density scan. Younger people should get a scan if they have a high-risk profile.
Last year my doctor recommended a bone density scan because of lower back pain I had, especially after running.
This is because a drop in oestrogen for a long time can cause a loss in bone mass, so have a bone density scan, especially with a family history of osteoporosis.
Before starting TRT, undergo a bone density scan, screening for prostate cancer and obstructive sleep apnea, and measurement of your hematocrit, the percentage of red blood cells in your blood.
Currently, assessing osteoporosis and the risk of fractures from small accidents like falls requires a bone density scan. But because these scans don't provide other relevant fracture-related information, such as bone size and the amount of force a bone is subjected to during a fall, each patient's bone density is examined against a national database of people with the same age and race or ethnicity.
These findings provide a basis for aging individuals to have their blood tested for leptin and request their body fat percentage be measured when they get their bone density scan. In the near future, a leptin blood test for reversal and treatment of obesity may become as common as testing cholesterol for heart disease and hemoglobin A1c for diabetes.
But if you're over 50 and have had an eating disorder, early menopause before 45) or have a family history of osteoporosis, see your GP about bone density scan.
If you fracture a bone and you have not been previously diagnosed with osteoporosis, talk with your doctor about having a bone density scan, and about lifestyle modifications that will help prevent bone loss, such as exercise, a healthy diet, and getting enough calcium and vitamin D.
