What is a DEXA Scanner?

In the realm of medical diagnostics, a DEXA scanner plays a pivotal role in assessing bone health. DEXA, which stands for Dual-Energy X-ray Absorptiometry, is a sophisticated imaging technique designed to measure bone mineral density (BMD). This technology employs a very low dose of ionizing radiation to create detailed images of the inside of the body, typically focusing on the spine and hip, which are critical areas prone to fractures in osteoporosis patients.

The accuracy and efficiency of DEXA scanners make them the gold standard in diagnosing osteoporosis and assessing fracture risk. The scanners at Nomad Fit Lab provide crucial data that help doctors and healthcare providers identify health conditions early, allowing for timely intervention and treatment. Beyond just measuring bone density, DEXA scans can also be used to analyze body composition, distinguishing lean tissue from fat tissue, which is increasingly important for managing various health conditions and for athletic training.

With its quick, non-invasive, and pain-free process, a DEXA scan is an essential tool in preventive healthcare. Regular screenings using DEXA scans are recommended for adults, especially postmenopausal women and older adults, to monitor bone health and prevent conditions that can lead to severe complications. Understanding what a DEXA scanner is and its usage can significantly contribute to maintaining bone health and preventing potential health issues.

How Does a DEXA Scanner Work?

To understand how a DEXA scanner works, we need to know the basics of X-ray technology. X-rays are a type of electromagnetic radiation that can pass through soft tissues but get absorbed by denser materials such as bones, creating distinctive images on a detector or film. A DEXA scanner uses two different energy levels of X-rays to measure bone density accurately.

During a scan with Nomad Fit Lab, the patient lies down on an examination table while a mechanical arm with an X-ray emitter moves over their body. The machine emits low and high-intensity beams simultaneously, which are then detected by sensors below the table. Based on how much radiation is absorbed by the bones, the device creates a detailed image, showing the difference between soft tissues and bony structures. The software then analyzes these images to calculate bone density accurately.

Once the scan is complete, a radiologist or healthcare provider can interpret the results and provide a report that outlines bone mineral density measurements and other critical findings. This information can be used to diagnose osteoporosis or assess fracture risk accurately. DEXA scans are quick, taking only 10-15 minutes, with minimal radiation exposure, making them safe for most individuals. Overall, DEXA scanners offer an efficient and non-invasive method of evaluating bone health and body composition. Book your next DEXA scan with Nomad Fit Lab today.
