Terms like X-ray and Dexa scan are common names used in medical history. But, many people are still unaware of the basic differences between the two. While both types of medical treatments use X-rays as the medium to detect health problems, their purposes remain very different. 

If a standard X-ray machine is useful for diagnosing bone and joint injuries, then Dexa Scan evaluates the bone strength. Read further if you are looking forward to expanding your knowledge to understand the differences between X-Ray and Dexa Scan. As we move forward, we will also see where to look for professionals while searching for X-rays near me. 

What is an X-ray scan?

X-ray scan uses ionising radiation to detect any internal problems in the body. This radiation process passes through the body to see issues like bone fractures, joint dislocations and abnormalities. When you go for an X-ray scan, doctors use an X-ray machine which produces high-quality images of your body parts. These images then help a medical practitioner detect issues with bone or joint problems.

What Can You Detect with X-Ray?

  • Bone fractures and trauma
  • Lung infections, Pneumonia, Tuberculosis, and Lung cancer.
  • Dental Radiography and jaw cavities

Are X-Ray Scans Safe?

Yes, X-ray scans are safe when you choose professional and trained medical experts who follow strict protocols. Typically, the side effects of radiation waves that our body absorbs are close to none. In this way, these waves cause no harm to our body’s internal structures. 

When should you see a doctor for X-ray scans?

Deciding when to see a doctor for an X-ray scan depends on your body symptoms, your medical history, and underlying issues. Here are some scenarios when you should see a doctor.

  • If you are experiencing excess pain in a specific body part after a fall or accident, then it is advisable to consult with a doctor. A practitioner will then likely conduct an X-ray scan to know the cause of your pain. 
  • A person with unknown bone or joint issues will likely experience immediate relief with X-ray scans. 
  • Sudden and continuous pain in some areas of the body can lead to an X-ray scan.
  • Chest pain, difficulty in breathing, and persistent cough.
  • Issues like gastrointestinal or digestive problems.

You must take care of your medical allergies and common health problems before going for an X-ray. As doctors may not be aware of your concerns, you should see a reliable one while looking for an X-ray near me.

Dexa Scan

Dexa scan (Dual-Energy X-ray absorptiometry) is a modern version of standard X-ray scans. It is a quick and painless process in which two X-ray beams are received inside the body. The first one goes inside the tissue, while the other one absorbs into the bones. 

The reason why Dexa scans are a popular test is because they accurately detect bone mineral density (BMD). Meaning, it examines the strength of your bone, mainly hip and spine bone density. 

Bone density helps assess whether you have fragile bones or if your bone density does not match the optimum level. In particular, it diagnoses Osteoporosis, which can result in major bone fractures without any symptoms. 

What Can You Detect with Dexa Scan?

  • BMD scores of young and healthy adults for a detailed comparison.
  • Risk of bone fractures in hip, spine and wrist.
  • Monitors Osteoporosis treatment to see changes in bone density.
  • Vertebral fractures
  • Secondary causes of bone loss 
  • Body Fat percentage 
  • Distribution of body fat

Can Dexa Scan Detect Body Fat Percentage?

Yes, the Dexa Scan machine can easily determine your body fat percentage. It will also consider different body areas to present accurate fat distribution. An alternative to BMI, the use of DEXA machines can help you figure out better weight management. 

Is Dexa Scan Safe?

Yes, Dexa scans are a better and more cost-effective alternative to CT scans. These tests radiate energy that is too low to leave any negative effect on the body. However, if you are a pregnant woman or someone who feels pain when lying down for a long time, then taking this test may not be suitable. 

When Should You See a Doctor for Dexa Scans?

A Dual-Energy X-ray absorptiometry (DEXA) scan should be done when you have the following reasons:

  • If you are over 40 or 50 and confirm the end of the menstrual cycle from the past 12 months, then a DEXA scan can help you assess bone health when you have experienced weak bones and hormonal changes. 
  • Men and women aged 70 or over can take a Dexa scan to determine conditions like Osteoporosis.
  • Certain medical problems like arthritis, hyperthyroidism, or other endocrine disorders.
  • Loss of height or unexplained weight loss
  • Long-term use of medications

Please note that Dexa Scan can be a long process, and appropriate care must be taken before taking this test. Avoiding calcium supplements and removing metal objects is one such measure to consider. Rest assured, finding a reliable medical imaging centre is another great way to ensure your safety.

Takeaway

Remember that X-rays and Dexa scans are valuable tools to understand and diagnose medical concerns. While X-rays offer images for possible fractures in many conditions, the Dexa Scan assesses bone density and body fat. 

We have walked you through the basic differences between the two above, and we hope that you have understood them clearly. Now, when you find options for X-rays near me, look for radiologists in medical centres who offer these services with the lowest possible radiation dose.
