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

This process usually takes less than 24 hours..

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.

Is a bone scan the same as an MRI?

A bone scan is just one imaging tool used to identify bone conditions in an individual. MRIs are also effective in producing internal images of the body that can be used to make proper diagnoses.

What do hot spots on a bone scan indicate?

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 …

What does cancer look like on a bone scan?

Radionuclide bone scans Bone scans can show if a cancer has spread to other bones. … Areas of diseased bone will be seen on the bone scan as dense, gray to black areas, called “hot spots.” These areas suggest cancer is present, but arthritis, infection, or other bone diseases can also cause hot spots.

What does a bone scan look for?

A bone scan is a nuclear imaging test that helps diagnose and track several types of bone disease. 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.

Where is bone cancer most common?

Bone cancer can begin in any bone in the body, but it most commonly affects the pelvis or the long bones in the arms and legs. Bone cancer is rare, making up less than 1 percent of all cancers. In fact, noncancerous bone tumors are much more common than cancerous ones.

Does bone cancer pain start suddenly?

The earliest symptoms of bone cancer are pain and swelling where the tumor is located. The pain may come and go at first. Then it can become more severe and steady later. The pain may get worse with movement, and there may be swelling in nearby soft tissue.

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.

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

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 bone cancer spread fast?

This is a rapidly growing tumor that often spreads to distant sites in the body, such as the lungs. It is most common in adolescents between 10–19 years of age. Although it is the second most common type of bone cancer in children and teenagers, it is very rare.

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.

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.

What are the side effects of radioactive dye?
