What Is The Difference Between A Bone Scan And A Bone Density Test?

How do you prepare for a bone density test?

Is there a prep for a bone density test?Stop taking calcium supplements, multivitamins and antacids, such as Tums, for 24 hours before your test.If you have had a barium or contrast x-ray exam, wait for 10 days afterwards to schedule your bone density test..

Why would a doctor order a bone scan?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray. A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate.

What happens if your bone density is low?

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.

Do you have to take your clothes off for a bone scan?

When you return the technologist will have you/your child remove clothing that has metal or other clothing fasteners like buttons or zippers. You will be given a hospital gown and/or pajama bottoms to wear if this is not possible. You will lie on an imaging table during the bone scan.

What does a bone scan tell you?

Bone scans are used primarily to detect the spread of metastatic cancer. Because cancer cells multiply rapidly, they will appear as a hot spot on a bone scan. This is due to the increased bone metabolism and bone repair in the area of the cancer cells.

What does a cold spot on a bone scan mean?

Areas that absorb little or no amount of tracer appear as dark or “cold” spots. This could show a lack of blood supply to the bone or certain types of cancer. Areas of fast bone growth or repair absorb more tracer and show up as bright or “hot” spots in the pictures.

What is a bone density test?

A bone density test measures how strong bones are. The test will tell you if you have osteoporosis, or weak bones. Women are at higher risk for osteoporosis than men, and the risk increases with age.

Is a bone density test really necessary?

Many people get a bone-density test every few years. The main reason to have the test is to find and treat serious bone loss, called osteoporosis, and prevent fractures and disability. Most men under 70 and women under age 65 probably don’t need the test because: Most people do not have serious bone loss.

Can you wear a bra for bone density test?

Do not wear jewelry, hearing aids, belt buckles, zippers, snaps, or buttons. Females should wear a sports bra. Bras with under wires will need to be removed. It is okay to eat anytime before or after the exam.

At what age should a woman have a bone density test?

When low bone density is identified early through screening, lifestyle changes and therapies can help protect bone health and reduce the risk of fractures. That’s why the U.S. Preventive Services Task Force recommends routine screening of bone mineral density for women ages 65 and older.

How long does it take to get bone density results?

The DXA bone density test is usually completed within 10 to 30 minutes, depending on the equipment used and the parts of the body being examined.

Can a bone density test detect arthritis?

Imaging Tests for Arthritis X-rays of joints and surrounding tissues. Magnetic resonance imaging (MRI), which takes a detailed picture of the joint using a computer, radiofrequency waves, and magnets. Ultrasound of the joint. Bone density scan (can also identify osteoporosis)
