What's a bone scan for?

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?

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

normal uptake: Bone scan involves intravenous injection of radiotracer 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 uptake is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. No abnormal uptake in skeleton is normal. ...Read more

Can you please tell me about a bone scan?

Bone function: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan with camera: 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 can I convert bone scan t-scores to z-scores?

How can I convert bone scan t-scores to z-scores?

Not usually: T scores are for patients over 18 yr and z scores for children under 18 yr. The controls for children are bases on ages, color, and sex. The t scores are compared to other adults. Dexa centers who perform studies on children have software to generate both values. T scores cannot be used accurately for children and z scores not in adults. ...Read more

Please tell me what happens during a bone scan procedure?

Imaging of skeleton: Bone scans differ at different institutions. All involve IV injection of radiopharmaceutical usually tc99m mdp, related to phosphorous, deposited in skeleton. Scan one or more phases. Immediate imaging after injection (angiographic phase) for minute, then soft tissue imaging 5 to 15 min after injection. All involve delayed imaging at 2-3 hours after injection. Part or whole body imaged with camera. ...Read more

I had a bone scan today and I saw white shots, what does that mean?

I had a bone scan today and I saw white shots, what does that mean?

Depends: That is really hard to say without seeing the study. Uptake of the material indicates bone metabolism....We often see more metabolism near joints. If there is a focal area of intense metabolism (in an area that doesn't usually look that way), it could be due to trauma (fracture), infection or even tumor. These things must be assessed together with history and other lab data. And physical exam. ...Read more

What to do if I'm having a bone scan tomorrow. What, exactly does a bone scan detect?

Bone activity: U R injected with a radioactive agent, which has a characteristic of tagging active bone growth cells. It will only tell someone where there is increased activity, such as in growth lines in the young, fracture healing, infection, and tumors of bone. Radiation exposure is negligible as the scanners R able to pick up the signals easily. ...Read more

What can I do if my latest bone scan shows results in both focal and linear areas, what is the difference?

Many possibilities.: It depends why you had your bone scan done. Focal lesions means "localized" and can have various shapes (circular, linear.) and various localizations. A linear lesion usually means a fracture or compression such as seen in the vertebral column. These are two different descriptive terminologies. Again, it should be easier to respond to your answer if we had the results of your scan. Good luck. ...Read more

Dr. Just ordered a bone scan to find out the density I guess never had one before can you please tell me how this test is done or all about it and why?

Bone Density: I'm assuming you mean a DEXA scan for bone density? It is a quick, simple, painless test. It is essentially equivalent to getting an X-ray. You lay on the scan table, the tech takes the scan, and you are done. No preparation necessary. ...Read more

How does nuclear medicine do a bone scan?

Tc-99m-MDP Bone Scan: Bone scan often provides an earlier diagnosis and demonstrates more lesions than are found by radiographic procedures. Tc-99m-mdp (methylene diphosphonate) is a bone seeking agent that concentrates in the mineral phase of bone. 2-3 hours after injection, 50%-60% of the activity localizing in bone and the remainder is cleared by the kidneys. F18-naf bone scans are done with pet cameras, r + expensive. ...Read more

What does strong uptake on a bone scan mean?

Increased activity: Strong uptake on bone scan means increased metabolic bone activity. This could indicate inflammation, fracture, infection, and/or bone tumor. These results usually are considered in the face of plain x-rays and exam to determine the diagnosis. Sometimes mri/ct scan are also needed. ...Read more

Please tell me, could a bone scan show organ tumors?

Please tell me, could a bone scan show organ tumors?

Yes: Tc-mdp is a common tracer used for bone scans. The delivery / localization of tracer relies on blood flow. Therefore areas of increased blood flow have higher delivery of tracer. In addition, any actively calcifying process can show tracer uptake. Liver metastases from colon cancer are often seen on bone scan. ...Read more

What's the difference between an X-ray and a bone scan?

Both radiation: Nuclear medicine radiation is given internally via IV injection, ingestion, or inhalation for determination of function of organs of body. Isotopes have different half lives and decay at different rates. Ct/xray is external radiation for visualization of anatiomy and pathology. Both contribute to radiation dose. Both are ionizing radiation. Ultrasound and MRI do not involve irradiation. ...Read more

Bone (Definition)
