The measurement of bone density in women, men, children is a test that should be done in some cases, in this article, especially in the case of menopausal bone resorption bone mass measurements will be mentioned.
Bone mineral density measurement is often referred to as bone scan, bone scan assay, bone scan test, bone resorption test, bone scan film, bone resorption film. Briefly written as BMD or BMD.
When and how is bone density measurement performed?
- After menopause
- Women over 65
- Those who use drugs that cause bone loss, such as steroids
- Patients with a history of hip fracture in themselves or mother
- Type 1 diabetes, liver and kidney disease
- Patients with severe hyperthyroidism
- Hyperparathyroidism patients
- Patients who have fractures with mild trauma
- Patients with suspected osteoporosis or spinal fractures in X-ray film
How often is the bone screening test done?
Bone density measurement is performed on average every 2 years after menopause, but can be performed more frequently in the presence of risk factors, or it can be done more rarely in people who do not have a risk factor with good bone density every 3-5 years.
How is bone mineral density measurement done?
DEXA (abbreviated as DXA) method, which is the most frequently used method to determine bone mineral density, is a simple, short-term, painless method. The patient lies on the device as shown in the picture and the operation is performed in this position. The patient is exposed to a very small amount of radiation beam, the amount of radiation taken is about a tenth of a dose in a lung x-ray film. The back part of the spine (L1-L4) and the hip (femur) are usually shot. Shooting lasts no more than 10 minutes, and after the shooting the result report is usually given to the patient within half an hour.
Whether the patient is hungry or full on the day of the measurement does not matter. He doesn't need to take any medicine before. Metal buttons, belts and non-zip fasteners should be preferred to avoid penetration. You can also shoot with a dress as long as the metal is not in the area, but sometimes you may be asked to take some clothes off.
To be able to flatten the lumbar region of the spine during shooting (for the lordosis to flatten), the patient's legs are placed on the support by pulling the legs towards the abdomen. In the hip shot, the femoral bone is turned inward (internal rotation).
Why is bone density measurement performed?
The main reason is to investigate the presence of osteoporosis. In addition, it is used to determine the risk of fracture. Hip fractures and spinal fractures are more common in patients with bone resorption. There was a direct relationship between bone mineral density (DEXA) and T-score. The lower the T score, the greater the bone resorption and the exponentially increased risk of fracture. In addition, bone density measurement is performed at certain intervals to observe the change occurring with the treatment and the benefit of treatment in patients treated for bone resorption.
