What is the difference between a bone scan and a CT 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 long does a whole body scan take?

A whole body bone scan takes around 3-4 hours, which includes two separate visits. In the first visit you will be given an injection of a radioactive isotope into a vein in your arm.

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.

What does it mean when a bone scan lights up?

During a bone scan, a radioactive substance called a tracer is injected into a vein in your arm. … 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.

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 arthritis look like on a bone scan?

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. These areas appear as dark patches on the film. … That’s because the spine is made up of so many little bones and joints.

How does a bone scan show cancer?

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 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.

Where is bone cancer most common?

Types of primary bone cancers include: Osteosarcoma, also known as osteogenic sarcoma, is the most common type of bone cancer and typically starts in bone cells in the arms, legs or pelvis. It occurs most frequently in people between the ages of 10 and 30, and is more common in males than females.

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

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.

Can a bone scan show inflammation?

Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. … [1] 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.

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 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.

What does a black spot 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. … 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.
