Synopsis (link)


Magnetic Resonance: A magnetic field splits spin energetic levels and induces spin precession. Energy transitions under conditions of Magnetic Resonance.

MRI: Polarization

A magnetic field induces spin polarization and a net magnetization

MRI: Detection

An RF tips the magnetization with energy absorption. During magnetization decay a signal (FID) is emitted.

MRI: Polarization enhancement techniques - Hyperpolarization

MRI: Detection RF pulse design

Inducing a Steady State Magnetization providing a continuously emitted signal from the subject
