How is a DEXA Scan Performed?
A DEXA scan, or Dual-Energy X-ray Absorptiometry scan, is a medical imaging procedure used primarily to assess bone density and diagnose conditions such as osteoporosis. It's a highly effective method for detecting early bone loss, allowing for timely intervention and treatment. Here’s a detailed look at how this crucial scan is performed.
Preparation for the DEXA Scan
Before undergoing a DEXA scan with Nomad Fit Lab certain preparations are recommended to ensure accurate results. Typically, patients are advised to avoid taking calcium supplements 24 hours before the scan. Comfortable clothing without metal fastenings should be worn, as metal can interfere with the imaging.
The Procedure
The DEXA scan is a quick, non-invasive, and painless procedure that usually takes about 10 to 30 minutes. During the scan, the patient lies down on a padded table while a scanning arm passes over the body. The DEXA machine emits two X-ray beams at different energy levels. These beams measure the amount of X-rays that pass through the bone, and the results are used to calculate bone density.
What to Expect During the Scan
Patients may be required to remain still and breathe normally, which ensures the clearest images are captured. In some cases, different positions may be requested, such as lying on the side or having a limb elevated. Nomad Fit Lab will position the patient accordingly to gather the most accurate results of bone density in areas like the hip and spine.
After the DEXA Scan
Post-procedure, there’s no downtime, and patients can resume normal activities immediately. Results are typically provided by Nomad Fit Lab within minutes. The results are presented as T-scores, which compare bone density to average peak bone density.
Understanding the Results
A T-score of -1.0 or above is considered normal, while a T-score between -1.0 and -2.5 indicates osteopenia, a condition of lower-than-normal bone density that may be a precursor to osteoporosis. A T-score of -2.5 or below signifies osteoporosis. Discussing these scores with a healthcare provider is essential for understanding personal health and necessary interventions.
A DEXA scan is a vital tool in maintaining bone health, enabling medical professionals to detect and address bone density issues proactively. Understanding the procedure helps in demystifying the process and encourages timely participation for those at risk of osteoporosis and related conditions. Talk to your healthcare provider today about the benefits of a DEXA scan and what it can do for your bone health. Remember, prevention is always better than treatment. So, it's important to prioritize regular DEXA scans as part of routine healthcare maintenance. Book your next DEXA scan with Nomad Fit Lab today.
