Magnetic Resonance Imaging
MRI
use magnetic fields and radio waves to create detailed images of organs and tissues in the body
You lie on a table that slides into the machine, which is deeper and narrower than a CT scanner. The magnets create loud tapping or thumping noises.
Duration: 45 minutes - 1 hour
ultrasound
uses high-frequency sound waves to produce images of organs and structures within the body.
A technician applies gel to your skin, then presses a small probe against it, moving it to capture images of the inside of your body.
Duration: 30 minutes – 1 hour
positron emission tomography scan
PET scan
use radioactive drugs (called tracers) and a scanning machine to show how your tissues and organs are functioning.
You swallow or have a radiotracer injected. You then enter the scanner (which looks like a CT scanner) which reads the radiation given off by the radiotracer.
Duration: 1.5 – 2 hours
