MRI
Magnetic Resonance Imaging
MRI scanner at Chesterfield Royal

MRI can produce two or three-dimensional image of what is going on side a patient’s body. It uses a large magnet, radio waves and a computer. The magnet is large enough to surround the patient.

 

MRI pictures are extremely precise – so precise that Doctors can often get as much information from MRI as they would from looking directly at the tissue.

 

MRI uses no x-rays and the magnetic fields MRI does use are not known to be harmful.
