In nuclear medicine a small injection of radioactivity is used to show how particular organs or tissues are working. This injection gives off radiation which enables pictures to be taken using a gamma camera. These pictures will give the doctor more information about the patient’s condition. Depending on the type of scan, the patient may need to wait up to a few hours for the injection to be absorbed before the images are taken. Upon arrival for the appointment, the injection is given through an arm vein. This is similar to having a blood test and will only take a few minutes. The patient will not feel any different after the injection; it will not make them sleepy or affect driving. Nuclear medicine procedures are time consuming and the radioactive material used has to be pre-ordered specifically from a radio-pharmacy outside of Medya Diagnostic Center. The order is made the day before the appointment.
