DXAmenetelmä

DXAmenetelmä, also known as Dual-energy X-ray Absorptiometry (DXA), is a medical imaging technique used to measure bone mineral density and assess bone health. It is a non-invasive, painless, and quick procedure that typically takes about 15-20 minutes to complete. During the test, the patient lies on a table that moves through an X-ray machine. The machine emits two different energy X-rays, which pass through the body and are detected by a sensor on the other side. The amount of radiation absorbed by the bones is measured, and this data is used to calculate bone mineral density.

DXA is commonly used to diagnose osteoporosis and other bone diseases. It is also used to monitor the effectiveness of treatments for these conditions. The test can be performed on any part of the body, but it is most often used to assess the hip, spine, and wrist. The results of a DXA scan are expressed in terms of bone mineral density, which is a measure of the amount of mineral in the bone. A low bone mineral density is an indicator of osteoporosis or other bone diseases.

DXA is considered a safe and effective method for assessing bone health. However, like any medical imaging technique, it involves exposure to radiation. Therefore, it is important to discuss the potential risks and benefits of the test with a healthcare provider before undergoing a DXA scan. The American College of Radiology and the European Society of Bone and Mineral Research provide guidelines for the appropriate use of DXA in clinical practice.
