No complications are expected from this procedure.

Studies of the health effects of radiation have shown that high doses of radiation can cause cancer.  However, this hospital procedure requires that we inject you with a very low level of radioactive material. 

The risk from lower doses of radiation, such as you will receive during this exam, is uncertain.  Most scientists believe that the risk is very small.  Certainly, the benefits received from the exam far outweigh the small risk associated with this procedure
