Is there a risk of using radioactive materials?
It doesn’t pose any danger to the patient if he/she follows the doctor's instructions. As the radioactive material gradually disappears with time and with frequent drinking of fluids, it is preferable not to approach children and pregnant women in the first hours after imaging.
What are the patient's preparations before imaging?
Most of the tests in nuclear medicine do not need special preparation, but some tests require the patient to be fasting or stop taking some medications for some time, and sometimes the patient must follow the instructions given by the reception staff when determining the date of the examination.
These radioactive drugs are considered like any medicine that is prepared with great care, and the tests are considered safe and the amount of radioactive medicine used is very few; so the patient is exposed to a similar amount of rays, or sometimes less than a diagnostic X-ray.
