What can a full body bone scan detect?
Full Body Bone Scan is a nuclear imaging test that helps diagnose and track several types of bone disease using tiny amounts of radioactive materials called tracers (radionuclides).
These tracers accumulate in certain organs and tissues, such as bones.
Impaired blood supply to the bones..
Does a bone scan show arthritis?
Areas of extra bone activity (common in both cancer and arthritis) will show up on the scan because the radioactive substance collects in areas of new bone formation. … With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone.
How accurate is a bone scan?
Ohta and colleagues compared PET and bone scan in evaluation of skeletal metastases in 51 patients with breast cancer and found that the sensitivity, specificity and accuracy of the bone scan were 77.7%, 80.9% and 80.3%, respectively.
Is a CT scan the same as a bone scan?
In computed tomography, the X-ray beam moves in a circle around the body. … 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.
How do I read my bone scan results?
Understanding Bone Density Test ResultsA T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9.A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. … A T-score of -2.5 or below is a diagnosis of osteoporosis. … The lower a person’s T-score, the lower the bone density.
How long does it take to get the results of a bone scan?
How soon will the scan results be available? A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.
What does a hot spot on a bone scan mean?
The areas where the radionuclide collects are called “hot spots,” and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and …
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 does a positive bone scan mean?
A bone scan is a nuclear medicine test. This means that the procedure uses a very small amount of a radioactive substance, called a tracer. The tracer is injected into a vein. It shows possible cancer in areas where too much or too little tracer has been absorbed by the body.
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.
Do you have to take your clothes off for a bone scan?
Having the bone scan You usually wear your own clothes for the scan but some hospitals may ask you to change into a hospital gown. Your radiographer will ask you to empty your pockets and remove any metal objects such as keys, coins, belts, braces and jewellery.
Can a bone scan show inflammation?
Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. …  Though the reported sensitivity of bone scan is high, its specificity is low due to increased metabolic activity seen in benign disease such as trauma, infection, inflammation, and degenerative joint diseases.
What do bright white spots on a bone scan mean?
Test Overview During a bone scan, a radioactive substance called a tracer is injected into a vein in your arm. … 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.
