A nuclear medicine exam uses very small amounts of radioactive material to help doctors diagnose diseases or medical conditions. These tests show the level of organ function and can show abnormalities in an organ’s structure or function.
- Depending on the type of nuclear medicine test, a radiotracer is injected into a vein, swallowed or inhaled.
- Some MRIs may require an injection of dye into a vein to give the radiologist more information about vascular structures in the body. If an IV dye is necessary for your exam, drink extra fluids for 48 hours following your exam to help flush the dye out of your body.
- Some procedures have delays allowing the radioactive tracer to take effect. These delays can be 2 to 4 hours or possibly several days depending upon the procedure.
- Some of these tests may take one hour or more.
