Study Notes

Magnetic Resonance Imaging (MRI)

MRI uses a strong magnetic field to align the spins of protons in hydrogen atoms.
Hydrogen is abundant in the brain due to its composition of water.
The alignment of proton spins in the magnetic field creates a polarization.
MRI generates static images by combining multiple snapshots of the brain.
The technology allows for the creation of both 2D slices and 3D models of the brain structure.
