What does abnormal uptake on a bone scan mean?

What does abnormal uptake on a bone scan mean?

Defects in uptake in the bone may be seen with a number of malignancies, typically lung cancer and breast cancer and occasionally in myeloma. Also through a number of benign diseases such as haemangioma, bone infarct associated with haemoglobinopathies and fat infiltration as in Gaucher’s disease.

What causes increased uptake on bone scan?

Thus, increased radiotracer uptake occurs with multiple pathologic processes such as fractures, infection, malignant disease and less commonly encountered osseous diseases like Paget disease, fibrous dysplasia, osteoid osteoma, and complex regional pain syndrome.

Can bone scan detect metastasis?

Using a bone scan when cancer is suspected can be particularly helpful because the scan can find both primary cancer—or, cancer that started in your bones—and bone metastases, which is cancer that has spread to the bones from another part of your body.

Does arthritis show up on a bone scan?

The test involves very little radiation exposure and poses no greater risk than a standard X-ray. Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone.

What do bone scans reveal?

Bone scans are used primarily to detect the spread of metastatic cancer. Because cancer cells multiply rapidly, they will appear as a hot spot on a bone scan. This is due to the increased bone metabolism and bone repair in the area of the cancer cells.

What is the highest T score for osteoporosis?

A T-score of −2.5 or lower indicates that you have osteoporosis. The greater the negative number, the more severe the osteoporosis….The T-score.
