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 detect infection?

How do I read my bone scan results?

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.

Does a bone scan show osteoporosis?

Unlike ordinary X-rays, DEXA scans can measure tiny reductions in bone density. This makes it possible to diagnose osteoporosis in its early stages, before you break a bone. A DEXA scan also uses a low dose of radiation, which means the risks to health are much lower than with standard X-rays.

Where is bone cancer most common?

Your ribs, pelvis, leg, and upper arm are the most common sites. It can also start in the soft tissue around your bones. Chondrosarcoma happens most often in people between ages 40 and 70. Your hip, pelvis, leg, arm, and shoulder are common sites of this cancer, which begins in cartilage cells.

What does a bone scan show?

A bone scan is a nuclear medicine test used to diagnose many different kinds of bone problems and diseases. The procedure uses a small amount of a radioactive substance called a tracer, which shows possible bone damage in areas where too much or too little tracer has been absorbed by the body.

What happens if infection gets into the bone?

An infection in your bone can impede blood circulation within the bone, leading to bone death. Areas where bone has died need to be surgically removed for antibiotics to be effective. Septic arthritis. Sometimes, infection within bones can spread into a nearby joint.

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