Relaxation: The Return to Equilibrium After the RF pulse is turned off, the protons do not remain in this excited state; they return to equilibrium through two distinct relaxation processes. Spatial Encoding and Image Formation Creating an image from the raw signal requires encoding spatial information into the MRI signal.
Understanding Principles of MRI T2 Decay Dynamics
T2 Relaxation and Decay T2 relaxation, or spin-spin relaxation, involves the loss of phase coherence among spinning protons, leading to a decay in the transverse magnetization. These gradients allow the scanner to determine the origin of the signal within the body.
This is achieved through the application of gradient magnetic fields, which temporarily and locally alter the strength of the main magnetic field. Fundamental Physics of Nuclear Magnetism The primary target of clinical MRI is the hydrogen nucleus, or proton, due to its abundance in water and fat.

These processes are fundamental to determining the contrast seen in the final images and vary between different tissue types, allowing for the differentiation of pathologies. This principle is critical for anatomical imaging and contrast agent enhancement.
