MRI (Magnetic Resonance Imaging) is a non-invasive imaging technique that uses a large magnet, radio waves, and a computer to produce 2 and 3 dimensional images of the body. MRI is often the imaging modality of choice because it does not use ionizing radiation such as x-rays, and there are no known long-term harmful effects
What is MRI?
How MRI Works
The MRI scanner is a large, tube-shaped magnet that provides a strong magnetic field around your child. A radio-frequency coil is placed over the body part to be imaged, which will be the brain for the purposes of our studies. The magnetic field, along with the applied radio-frequency waves, will temporarily alter the alignment of hydrogen protons found in water molecules within the body. Computers then construct the images of the brain based on the radio-frequency signals emitted by the protons.
