densitometriaan

Densitometriaan, often referred to as bone densitometry, is a medical imaging technique used to measure bone mineral density (BMD). It is the most common method for diagnosing osteoporosis and assessing an individual's risk of fracture. The most widely used type of densitometry is dual-energy X-ray absorptiometry (DXA or DEXA). This non-invasive procedure uses a low dose of X-rays with two different energy levels to penetrate bone and soft tissue. By analyzing the differential absorption of these X-rays, the machine can accurately determine the mineral content of the bone.

The primary sites measured are usually the lumbar spine and the hip, as these areas are prone to fractures in individuals with low bone density. The results are typically reported as T-scores and Z-scores. A T-score compares an individual's BMD to that of a healthy young adult of the same sex. A Z-score compares BMD to individuals of the same age, sex, and ethnicity. These scores help physicians determine if bone density is normal, low (osteopenia), or indicative of osteoporosis.

Densitometriaan is also used to monitor the effectiveness of osteoporosis treatments and to identify individuals who might benefit from preventative measures. It is generally recommended for postmenopausal women, men over 65, and individuals with certain medical conditions or taking medications that can affect bone health. The procedure is quick, usually taking about 10 to 20 minutes, and involves lying on a padded table while the scanner passes over the body.
