Why are injections required before doing a bone scan to check for a stress fracture?

Only one: Only one inflection is needed. That is the injection of tc-mdp, the tracer taken up by he bones and detected by the nuclear medicine camera. This tracer shows active bone turnover and is focally "hot" in sites of fracture.

Blood to skeleton: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. Bone scan very sensitive but not specific.

Radiotracer injectio: A bone scan or bone scintigraphy is obtained few hours after the injection of a radiotracer ( usually 99mtc-mdp). The distribution of this radiotracer in the various bones will be detected by a specific type of camera named gamma camera ( to detect the gamma rays from 99mtechnetium). This is the contrary of a bone x-ray where external radiation source is used.

What causes you to need to get an injection to do a bone scan to check for a stress fracture?

Radiotracer: A nuclear medicine bone scan is used to evaluate for conditions affecting bones including cancer, fractures, degenerative diseases etc. The radiotracer or radioactive material used is injected through a vein quickly reach your bones where it is deposited. A gamma camera is used to detect the radiotracer and images are created. The radiation is cleared from your body mostly in urine.
