Nuclear Medicine

Nuclear medicine is primarily used to examine organ function rather than structure. To see how an organ is working, a patient ingests a small amount of radioactive material. By measuring the behavior of the material during a nuclear scan, an assessment can be made. The sites below provide an introduction to nuclear medicine, including how nuclear medicine scans are performed and what to expect during such a scan.

Dulcinea's Insight

  • The amount of radioactive material a person swallows or is injected with for nuclear medicine scans is very small, and usually leaves the body a day or two after the test.
