False-colour scintigram (bone scan) of a normal chest in anterior view. The scintigram is a map of radioactivity from a tracer,which is injected into the subject prior to taking the scan & which becomes concentrated in bone. Radioactivity passes through the body to be recorded by an external gamma camera. Technetium-99m linked to MDP is the tracer of choice for bone scans. This technique is used to screen cancer patients for secondary disease (metastases) in the follow-up to treatment of their primary cancer. The increased uptake of radioactivity in cancerous bone is revealed as abnormal,"hot spots" on a bone scan | |
