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 …
Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. It is used in the evaluation of benign bone disease like infection/inflammation and also is the standard of care for evaluating metastatic disease in the breast, prostate, and lung cancer.
Subsequently, What does a lesion on the rib mean?
Bone lesions are areas of bone that are changed or damaged. Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous.
Also, What does cancer look like on a bone scan?
Bone scans also can show how much damage the cancer has caused in the bone. 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 cancers cause bone lesions?
– Breast cancer.
– Kidney cancer.
– Lung cancer.
– Lymphoma.

What can a full body bone scan detect?
To detect conditions such as arthritis , benign bone tumors, Paget’s disease (a bone disorder, usually occurring in people over age 50, in which there is thickening and softening of the bones, and curving of the long bones), and avascular necrosis (death of bone tissue due to loss of blood supply to the bones)
What do dark spots on bone scan mean?
Areas that absorb little or no amount of tracer appear as dark or “cold” spots. This could show a lack of blood supply to the bone or certain types of cancer. Areas of fast bone growth or repair absorb more tracer and show up as bright or “hot” spots in the pictures.
How does arthritis show up on a bone scan?
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. These areas appear as dark patches on the film.

How does cancer show up on a bone scan?

Bone scans may also be used to stage the cancer before and after treatment in order to assess the effectiveness of the treatment.
What machine is used for a bone scan?
Gamma cameras and PET scanners are the 2 basic types of cameras used to image the radioactive decay from the radiotracers utilized in bone scintigraphy.
How does caffeine affect PET scan?
If a person exercises before having a PET/CT scan, more FDG appears in the heart region, obscuring the view. … The researchers found that the same thing happens with caffeine: The heart beats faster when you drink coffee, just as it does when you exercise.
