DIE RADIOLOGIE offers the measurement of bone density in the practice network. The decrease in bone mass and consequently in bone density is a normal part of the aging process.
We are here for you.
Our doctors and assistants accompany you sensitively and professionally during your visit. We ensure quick examinations in a relaxed atmosphere – our doctors and medical staff ensure smooth processes and always strive to make you feel relaxed and safe during the examination.
With increasing age, hormonal influences in particular lead to degradation and thinning processes within and on the outside of the bone. The result of these processes is reduced bone stability with an increased risk of fractures – sometimes even with only a small load. The vertebral bodies of the lower thoracic and lumbar spine and the femoral neck are particularly at risk. It is measured with dual X-ray absorptiometry, the so-called DEXA method (Dual Energy X-Ray Absorptiometry).
The bone density measurement takes only a few minutes, is absolutely painless and only involves a very low level of radiation exposure.
How is a bone density measurement performed?
Bone mass can be determined by determining bone density. During the DEXA measurement, the patient's body is exposed to very weak X-rays, which are weakened primarily by the bones as they pass through the body. Finally, this attenuation of the rays can be measured and imaged.
Information about the examination
Bone density examination using the DEXA method
The DEXA method (Dual-Energy-X-ray Absorptiometry) uses a special X-ray technique to measure the bone density in the femur and the lumbar vertebrae – two bone regions where osteoporosis is particularly often and clearly detectable. The examination takes place lying down on the special examination table of the bone density measuring device and takes about 10-20 minutes.
Where is bone density measured?
The measurement is usually taken at the lumbar spine and left femoral neck. Using reference models, the bone density value – the "T value" – can then be determined via the degree of X-ray attenuation.
Prevention, diagnosis and follow-up
Bone density measurement is used to diagnose pathological bone loss (osteoporosis), for example in elderly patients with back pain or new vertebral fractures. It is also used to assess the success of osteoporosis treatment. Bone density is checked at regular intervals during the course of therapy.
After the examination, we will discuss the result with you and advise you in detail if further measures are necessary. You will get the imagery right away. The actual report is sent directly to the referring colleague. If you are not yet under medical care and if further treatment is necessary, we will be happy to put you in touch with a specialist.
Bone density measurement is also particularly important in the early detection of osteoporosis. Bone density decreases rapidly, especially in women going through menopause and men over the age of 50. Especially if there are other risk factors, it makes sense to use a bone density measurement to determine your personal risk of developing osteoporosis.
Important risk factors for the development of osteoporosis are, for example:
- Hereditary predisposition
- Excessive alcohol consumption
- Underweight, malnutrition or vitamin deficiency
- Poor physical activity
- Prolonged cortisone therapy
- Various diseases, for example of the thyroid, the gastrointestinal tract and the kidneys
There are many things you can do if your bone density is too low. Prevention and treatment of the disease can significantly reduce the risk of fractures.
- Osteopenia ( = low bone mass): Bone mineral content: T-value from -1.0 to - 2.5 (pre-stage of osteoporosis)
- Osteoporosis (excluding fractures): Bone mineral content: T-score < -2.5
- Manifest osteoporosis (with fractures): Here the bone mineral content is so low that bone fractures can occur without a triggering event (accident). (T-score < -2.5)
The Z value, on the other hand, is a benchmark for comparing the measured bone density with people of the same age.
When measuring bone density using quantitative computed tomography, the bone density in the lumbar spine is measured with the help of x-ray images. The examination takes place lying down in a computed tomography device and takes about 10-15 minutes.
With both examination methods, the measurement result is evaluated after the examination with special computer programs. The measured values are compared both with the reference values of young, healthy adults and with the values of adults of the same age and sex as the patient. Based on the results, the doctor can assess whether your individual bone density is within the normal range.
