Different Approaches to Testing Bone Density
When it comes to testing bone density, various methods are employed. Some scans solely focus on the fingertips, while others take a more comprehensive approach by examining the forearm, hips, and spine. These areas are particularly prone to fractures in the event of an accident. Peripheral tests are conducted on individuals who lack insurance coverage or are unable to undergo x-rays due to excessive weight. For a more precise assessment of bone density, a DXA or DEXA scan is necessary. This type of scan involves imaging the entire body and can identify areas of porous bone.
Understanding the Process of a Bone Density Test
A bone density test, also known as a DXA scan, is a comprehensive examination that primarily focuses on the hip and spine. This non-invasive procedure involves the use of low-dose X-rays to determine the density of the bones. By analyzing how much the X-rays change after passing through the skeletal structure, a detailed image is produced by the machine.
During the test, the patient lies comfortably on a padded platform, fully clothed. A mechanical arm passes over the body, emitting the low-dose X-rays. The entire process typically takes around 10 minutes to complete. This centralized DXA scan provides a thorough assessment of bone density and strength.
However, there is also a peripheral device available for bone density testing. This portable alternative enables individuals who may not have access to the central DXA scan to undergo the test. This portable device allows for greater accessibility and convenience in diagnosing bone health.
