Bone imaging is an extremely important use of radioactive properties.
Supposed a runner is experiencing severe pain in both shins. The doctor
decides to check to see if either tibia has a stress fracture. The runner
is given an injection containing 99Tcm. This radioisotope is a gamma ray
producer with a half-life of 6 hours.
After a several hour wait, the patient undergoes bone imaging. At this
point, any area of the body that is undergoing unusually high bone growth
will show up as a stronger image on the screen. Therefore if the runner
has a stress fracture, it will show up on the bone imaging scan.
This technique is also good for arthritic patients, bone abnormalities
and various other diagnostics.
Still need to describe mechanism!!
