What is a bone densitometry scan?

A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. You may also hear it called a DEXA scan. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break.

How long do bone density scans take?

The scan usually takes 10 to 20 minutes. You’ll be able to go home after you have had it done.

What is the difference between a bone density scan and a DEXA scan?

What is a bone density scan? A bone density scan, also known as a DEXA scan, is a type of low-dose x-ray test that measures calcium and other minerals in your bones. The measurement helps show the strength and thickness (known as bone density or mass) of your bones. Most people’s bones become thinner as they get older.

How much does a DEXA bone density scan cost?

A DEXA scan costs about $125. And if your doctor prescribes a drug when you only have mild bone loss, you spend money you don’t need to. A month’s supply of generic alendronate can cost as much as $75.

Why would a doctor order a bone density test?

Doctors use bone density testing to: Identify decreases in bone density before you break a bone. Determine your risk of broken bones (fractures) Confirm a diagnosis of osteoporosis.

How can I check my bone density at home?

Single energy x-ray absorptiometry – a single x-ray beam is used to measure bone density at peripheral sites like the forearm and heel. In this technique, the area to be tested is wrapped in a tissue-like substance or immersed in water to improve the quality of the results.

Can I wear a bra for a bone density test?

Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra. Gowns are available, if necessary.

What types of illnesses conditions is bone scanning used to diagnose?

Bone scans can help diagnose several problems, including: Broken bones, especially hips, or stress fractures, which can be hard to see on X-rays. Arthritis. Paget’s disease of the bone, which affects how new tissue replaces the old.

What is the difference between a bone scan and a PET scan?

Conclusions The difference between bone scan and PET/CT for detection of bone metastases may be attributable to the different mechanism. Bone scan depends on the osteoblastic response to bone destruction by tumor cells,and FDG-PET/CT detects the metabolic activity of the tumor cells.

Do I have to undress for a bone density scan?

In most cases, you do not need to undress. This scan is the best test to predict your risk for fractures, especially of the hip. Peripheral DEXA (p-DEXA) — These smaller machines measure the bone density in your wrist, fingers, leg, or heel.

Is a bone scan a PET?

A PET bone scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. F18 fluoride is the tracer that will be used for your bone scan. PET F18 fluoride bone scans are done most often to detect metastatic bone disease (cancer that has spread from an organ to the bone).
