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.
