What is the difference between a CT and MRI scan?
Queen Square Senior Neuroradiographer Kirsty Price explains the differences between MRI versus CT scans, which stands for Computed Tomography and is also used for looking closely at bone and blood
Transcript
So MRI stands for Magnetic Resonance Imaging, CT stands for Computed Tomography. MRI uses magnets and radio frequency pulses to get images of the soft tissue in the body. CT is a very advanced type of X-ray machine so there is ionizing radiation with CT, and it takes images by firing very high energy X-rays through the patient. CT can be used to look at things like bone and blood, and soft tissues as well, but they give completely different images. So MRI is non-ionizing radiation, CT is a really complicated, really high-energy X-ray machine, and they're used in totally different ways.
