Osteoporosis , a common cause of deformation and fracture of bones - a decrease in bone density due to the loss of important elements , especially calcium . The disease is asymptomatic, but it can be detected by densitometry - the study of the mineral composition of bone tissue. Today it is the only method to detect osteoporosis early. How to carry out densitometry ?
First studies of bone density were performed using ultrasonic instruments scanners - densitometers , but complete and realistic picture , they were not given. Today, experts around the world use X-ray densitometry. X-ray irradiation dose received by the patient during the procedure, is 20 times less than when fluorography .
Densitometer equipped with a sensor that makes measurements of the intensity of the rays passing through the body (low bone density holds less than X-rays).
- the state of the spine, including the identification of vertebral fractures;
- the degree of thinning of bone tissue;
- the mineral content in the studiedparts of the body and around the body.
Densitometry is painless, non-traumatic . Depending on the doctor's instructions , it can be carried out , for example, once a year or every two years . Diagnosis may be made only three points of the skeleton of the patient , the most prone to fractures :
- the forearm (radial bone fractures);
- lumbar spine (vertebral compression fractures);
- the femur (hip fracture - particularly dangerous for the elderly who have complicated fusion of the bones).
Densitometry was carried out again if, after a certain period of treatment is necessary to evaluate the effectiveness of therapy.
This shows densitometry?
Densitometry should be performed:
- the elderly;
- menopausal women (one in three women in this time show signs of early stage of osteoporosis - osteopenia);
- people taking drugs, glucocorticoids (output of calcium from the body);
- people suffering from diseases of the gastrointestinal tract, blood, kidneys, endocrine organs.
