What's a bone scan for?

Bone metabolism: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. Bone scan very sensitive but not specific. ...Read more

How does a bone scan work?

Images calcium metab: Usually in adults the bone scan is used to detect metastatic cancer. It also is frequently used to evaluate for possible stress fractures in people with bone pain. There are many additional uses. It works by injecting a tracer that is taken up in bone similar to calcium. The small amount of radioactivity is then imaged with a camera (gamma or pet) utilizing fluorescence from the crystal. ...Read more

What do bone scan results tell you?

What do bone scan results tell you?

Hot spot, cold spots: The radiologist looks for evidence of abnormal bone metabolism on the scans. These show up as darker "hot spots" and lighter "cold spots" where the tracers have or haven't accumulated. Although a bone scan is very sensitive to abnormalities in bone metabolism, it's less helpful in determining the exact cause of the abnormality. ...Read more

What lights up in a normal bone scan?

New bone matrix: The injection is something that your body uses like a phosphate (methylene diphosphonate). In general when your body makes new bone, it will "grab" some of this. In young people we see more uptake near the ends of bones where they are growing. All bones will pick a little up since we are always making new and loosing some of the old. Kidneys filter out the rest. ...Read more

Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
