Densitometry in Krajmed
Densitometry is the only test that can confirm or rule out osteoporosis and assess the risk of the disease (performed on patients aged 17 and older). Densitometry is a painless test, just like ultrasound and X-ray. The radiation dose is minimal. Only spine and femoral neck densitometry can assess fracture risk and make treatment decisions. Forearm or heel examinations are not recommended and no diagnosis can be made based on them. Spinal densitometry best evaluates early peri-menopausal changes that are not seen in the femoral neck. A neck study assesses the risk of long bone fractures. A complete densitometry study includes the lumbar spine and femoral necks.

What is densitometry?
Densitometry is an essential test in the diagnosis of osteoporosis and osteopenia. It is a two-dimensional variant of computed tomography. It is based on radiological evaluation of the absorption difference between bone and fat and muscle tissue. The measurement value is expressed two-dimensionally in grams (BMC – Bone Mineral Content) and in g/cm2 (BMD – Bone Mineral Density).
Densitometry in Warsaw can also be successfully performed in the diagnosis of atypical infections caused by CHLAMYDIA and as an adjunctive method in determining diet in obese patients.
How is the bone density test performed?
Bone density testing is performed on a high-quality densitometer. The percentage error of measurement for the densitometer we use is %CV = 0.08% (on average for densitometers of older types %CV is about 1%, acceptable error %CV=1,8% [standard ISCD] ).
LSC (least significant change) for the densitometer we are using
LSC = 2.77 * %CV, LSC = 2.77 * 0.08%, LSC = 0.002 g/cm2
[dopuszczalny normą ISCD błąd lsc=”0,050″ g/cm2]
The accuracy of the device allows, if necessary, to reliably monitor patients over 3-month periods (important in patients on steroid therapy).
Who should go for densitometry?
- Women over 65, men over 70
- Postmenopausal women with risk factors for osteoporosis
- Individuals after fractures or under the influence of diseases, medications or factors that are associated with reduced bone mass or cause accelerated bone loss
- before starting drug therapy
- during treatment to monitor therapy
- anyone whose densitometry test prompts them to start treatment
- Women in whom hormone replacement therapy has been discontinued
