Magnetic Resonance Imaging (MRI)

MRI creates images from the magnetic resonance created in hydrogen atoms when they are polarized and an electromagnetic pulse is used to knock them off axis. This section includes MR analysis software, MRI scanners, gadolinium contrast agents and related magnetic resonance imaging accessories.
