Nuclear Medicine
A nuclear medicine image or scan involves the intravenous injection of a small amount of radioactive tracer. Images are taken from several angles with a scintillation camera.
Since the radioactive drugs are very low concentration, reactions are virtually nonexistent and the radiation dose is approximately equal to that of a chest X-ray.
Preparation
Most nuclear exams require no preparation.
Length of Procedure
Most nuclear medicine studies require approximately 45 minutes to one hour of imaging time.
However, some procedures require additional time between injection of the tracer and the actual imaging.
In the spirit of Christ and the example of Francis of Assisi, the Mission of OSF HealthCare is to serve persons with the greatest care and love in a community that celebrates the Gift of Life.
