Will a bone scan show disc problems?

Bone Scans Are Reliable for the Identification of Lumbar Disk and Facet Pathology..

Are body scans accurate?

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

CT scans of the bones can provide more detailed information about the bone tissue and bone structure than standard X-rays of the bone, thus providing more information related to injuries and/or diseases of the bone.

Will a bone scan show arthritis?

Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. But it can be hard to tell the difference between arthritis and cancer — especially in the spine.

How long does it take to get the results of a bone scan?

24 hours before your appointment: Refrain from consuming any caffeine, including any decaffeinated products.

Does inflammation show up on a bone scan?

Both ultrasound and MRI can detect synovitis, inflammation of the lining of the joints, and tendon abnormalities. In addition, MRI detects areas of increased fluid (edema) in bone marrow that is a predictor for the development of bony erosions.

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

You may have to wait several hours between the radiotracer injection and the bone scan so you may want to bring something to read or work on. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.

Why do I need 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.

Can you have a CT scan and a bone scan the same day?

Bone Scan, Skeletal Imaging If a CT scan is scheduled for the same day, an IV line will be placed prior to the injection for the bone scan. You may not eat until after the CT scan is completed.

What does an abnormal bone scan look like?

Results are considered abnormal when the scan shows darker “hot spots” or lighter “cold spots” in the bones. Hot spots describe places where an excess of radioactive substance has collected. Cold spots, on the other hand, are areas where it didn’t collect at all.

Does a bone scan show osteoporosis?

If you are pregnant or suspect you may be pregnant, you should notify your health care provider.

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

And the denser your bones, the stronger they generally are and the less likely they are to break. Bone density tests differ from bone scans. Bone scans require an injection beforehand and are usually used to detect fractures, cancer, infections and other abnormalities in the bone.

What do bright spots on a bone scan mean?

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. Hot spots may point to problems such as arthritis, a tumor, a fracture, or an infection.
