Positron emission tomography (PET) – Information Sheet
Positron emission tomography (PET) requires patients to be injected with a radioactive substance, which is detected by scanner and used to form an image.
-
Radiation – Information Sheet
There are many different types of radiation (the emission of energy from a source). Most radiation travels as a wave, and some has so much energy that it travels as particles.
-
Ultrasound – Information Sheet
Ultrasound is a medical imaging technique that uses high frequency sound waves and their echoes, developed from radar and sonar technologies.
