Bone Density Test – Purpose And Procedure

The bone density test is a painless and quick bone scan used to diagnose osteoporosis in a body. The doctor usually recommends the test in case of fractures and aging. A bone density test determines the number of minerals in the bones.

Low radiation doses are used in bone density scans and are available in Perth Amboy diagnostic imaging. Most people don’t have any problems with it. However, pregnant women are not advised to take it. The effects of radiation on an unborn baby could even be severe at low doses. Tell your health care provider if you think you are pregnant or are planning to become pregnant.

What is Osteoporosis?

The term osteoporosis is derived from a Greek word that means “porous bone.” Osteoporosis is the loss of bone density. As a result, the bones become weak and brittle due to osteoporosis, leading to fractures even when bending over or coughing. Hip, wrist, and spine fractures are the most common osteoporosis-related fractures.

The bone is constantly breaking down and being replaced by new tissue. However, due to osteoporosis, new bone is not being created quickly enough to replace the damage incurred by the bones.

Everyone is at risk for osteoporosis, regardless of race. However, the highest risk is posed by white and Asian women, especially in post-menopause. Bone strength or prevention of bone loss can be achieved with medication, a healthy diet, and weight-bearing exercise.

What Causes Osteoporosis?

The bones of your body are continually being made and broken down – new bone is constantly being formed. A person’s bone mass increases when they’re young since new bone is formed quicker than old bone is broken down. Most people reach their peak bone mass by age 30 after going their peak bone mass in their early 20s. The amount of bone mass lost by people as they age becomes greater than the amount they create.

It is partly determined by how much bone mass you achieved in your youth and whether you will develop osteoporosis later in life. In addition to being inherited, peak bone mass also varies by ethnicity. In addition to having more bone “in the bank,” a high peak bone mass makes you less likely to develop osteoporosis in old age.

Purpose Of Bone Density

The purpose of bone density is to determine the presence of osteoporosis in the body. Regardless of age and sex, this condition can be observed in any person. However, it is pretty common in females above 35 years.

A bone density test is usually recommended for the ones facing a road accident. It is because a decrease in bone density can make the bones fragile. Some of the most common reasons for getting bone density tests are listed below:

  • Hormonal changes

A drop in the body’s hormonal level is one of the purposes of getting a bone density test. Hormones in the human body play an essential role in regulating all the procedures of the human body. Therefore, the sudden drop in the hormonal level of the human body can be a reason to cause osteoporosis. It is usually common in females after menopause. The estrogen level in females also drops during specific cancer treatments.

  • Fractured Bone

Several factors contribute to making a bone fragile and cause a fracture. The other purpose of getting a bone density test is the occurrence of road accidents in the past. The bone density test helps in determining the fracture risk and bone fragility.

  • Use Of Some Drugs

The excessive usage of drugs can lead to the loss of bone density. Prednisone, for instance, interferes with bone-rebuilding, resulting in osteoporosis when used long-term.

Bone Density Scan Procedure

An X-ray scan is usually performed by a radiographer, who is an expert in taking these images. Bone density in the center of the skeleton will be measured using a large scanning arm during the scan.

An X-ray beam is passed through the part of your body being examined as the scanning arm moves slowly over it. For example, in order to check for weak bones (osteoporosis), your hip and lower spine will usually be examined. It may be necessary to scan more than one part of your body since bone density varies from one part to another.

It may be necessary to scan the forearm if the hip or spine scans are impossible or if hyperparathyroidism is present. In addition to fat and bone, some X-rays are absorbed by your body’s tissues. The scanning arm is equipped with an X-ray detector that measures the number of X-rays you have taken.

Results Of Bone Density Scan

The bone density of a healthy adult of your age, gender, and ethnicity is compared with your own bone density. Using the standard deviation (SD) score, we can calculate the difference between the two scores. Bone density is measured as the difference between what you have and what you should have.

An individual’s T score is the difference between their measurement and that of a young and healthy adult. It is known as a Z score when the measurement of you and someone of the same age differs.

Conclusion

Bone density scans, or DEXA scans, are low-dose x-ray examinations that determine the calcium levels in your bones. This measurement determines the density or mass of your bones (also known as strength and thickness). Older people tend to have thinner bones. An osteopenia condition occurs when a person’s bones become thinner than normal. In addition, having osteoporosis increases your risk of osteoporosis, which is a more serious condition.

The bone is constantly breaking down and being replaced by new tissue. However, due to osteoporosis, new bone is not being created quickly enough to replace the damage incurred by the bones.

Everyone is at risk for osteoporosis, regardless of race. However, the highest risk is posed by white and Asian women, especially in post-menopause. Bone strength or prevention of bone loss can be achieved with medication, a healthy diet, and weight-bearing exercise.

Bones become thin and brittle due to osteoporosis, a progressive disease. Most women over 65 are affected by osteoporosis, which generally affects older people. Hip, spine, and wrist fractures are more likely to occur in people with osteoporosis.
