Magnetic resonance imaging (MRI) is a safe and painless test that uses a magnetic field and radio waves to produce detailed pictures of the body's organs and structures.An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it doesn't use radiation.This is not an indication of a security issue such as a virus or attack.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.
The following video will help you and your child understand what to expect during a sedated MRI procedure at Children's Hospital.
An MRI scanner consists of a large doughnut-shaped magnet that often has a tunnel in the center.
Patients are placed on a table that slides into the tunnel.
A radiofrequency coil is placed over the body part that is to be imaged.
The magnetic field, along with applied radiofrequency waves, temporarily alters the alignment of hydrogen protons found in water molecules within the body.
