Functional imaging using small amounts of radioactive tracers.
Nuclear medicine uses very small amounts of radioactive material (radiotracers) to evaluate how organs and tissues are functioning. Unlike CT or MRI which show anatomy, nuclear medicine shows physiology — what's working and what isn't.
A radiotracer is administered — usually by IV, sometimes oral or inhaled.
Waiting time varies from 15 minutes to several hours depending on the study.
You'll lie on a table and a gamma camera will image you.
Imaging takes 30–60 minutes.
Some studies have multiple imaging time points across the day.
Preparation depends on the specific study. Detailed instructions will be provided when you schedule your appointment.
The radiation dose from nuclear medicine is comparable to a typical CT scan and is considered safe for adults. Notify us if you are or could be pregnant or breastfeeding.
