A bone scan is a test that uses nuclear imaging to helps diagnose and track several types of bone disease
Nuclear imaging involves using small amounts of radioactive substances, a special camera that can detect the radioactivity and a computer scanner to see structures such as bones inside the body.
The tracer is absorbed more by cells and tissues that are changing or having unusual properties
The scanner then picks up the radiation.
The picture made by the areas of radiation gives your doctor a kind of map of unusual areas in your bones.
