All You Need To Know Before Opting For A DEXA Scan

In case you're unaware, a DEXA scan is carried out to measure or assess the bone density of the human body. The scan also helps in determining the body composition, including the overall percentage of fat and lean muscle. DEXA or otherwise known as dual-energy X-ray absorptiometry scan uses a dual-layer X-ray beam directed towards the bones of the human body. As a result, two separate images are formed - one for the bones and the other for the soft tissues. 

The DEXA scan in London is carried out to inspect whether a person is suffering from low bone density or the overall condition is getting worse. This scan is much more accurate than any typical X-ray because it can detect any small changes in the loss of bone density. Moreover, most doctors out there consider the scan to be reliable especially when calculating body fat percentage and the risks of developing a bone fracture. 

What Is The Main Purpose Of Getting A DEXA Scan?

One of the main purposes of opting for the DEXA scan is to assess the current condition of the body’s bones of a person and whether the bones are at the risk of fracturing. With the help of this scan, doctors can easily diagnose osteoporosis. Osteoporosis is a deficiency disease that is caused due to the low amount of calcium minerals present in the human body. Due to osteoporosis, the bones of the body start to lose density or becomes thin. And when the bones become thin, they become fragile and thereby become susceptible to breaking. 

Therefore, determining whether a patient has osteoporosis beforehand will help in preventing the issue from becoming worse. Moreover, the risk of fractures will be reduced as well. 

Once the first DEXA scan has taken place, the specified doctor will suggest another scan to be carried out within a couple of years, so that it could be seen whether the density has changed over time. Apart from that, the DEXA scan can also help in TIMELY osteoporosis treatments. It has been reported that females who are above the age of 65 and males who are above 70 years of age, should proceed to get a DEXA scan. People who are currently receiving osteoporosis treatments should obtain a re-scan within one or two years of the previous scan. 

Females who are younger than 65 years but are post-menopausal, also carry the risk factors of having low bone density. Generally, females are recommended to opt for such a scan at an early age than males because the tendency to lose bone density is more in females than males. 

The Procedure

It should be known that there’s no special preparation that a patient needs to undertake before a DEXA scan. The patient can proceed to drink and eat normally as he or she would do on any other day. On the other hand, if any patient is undertaking calcium supplements, then the same must be stopped at least 24 hours before the scan takes place.

According to a professional dietician in London, the patient who will be undertaking the scan will wear a hospital gown and any metal objects must be removed. The technician will place the X-ray generator below the patient and the imaging device above the patient. 

The scan is usually painless and will only take up to 30 minutes to be completed. However, pregnant patients must talk to their doctors because this scan involves radiation.
