Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a scanning procedure that uses strong magnets and radiofrequency pulses to generate signals from the body. These signals are detected by a radio antenna and processed by a computer to create internal images of the body.
The MRI scanner is shaped like a large, covered box with a tunnel passing through it. A table, on which you lie, slides into the open-ended tunnel.
Safety in the MRI scanner is vital. The strong magnetic fields can attract and interfere with metal objects that you might have in or on you. To ensure it is safe for you to have an MRI, you will be required to complete a safety questionnaire.
If you are pregnant, have a pacemaker or other implant, it is important to tell the radiology staff and provide relevant documentation before having the scan. This information can help to assess if it is safe for you to have the MRI.
