Study Notes

MRI Definition

Provides cross-sectional images, eliminating the problem of structure superposition.
Employs magnetic fields and radio waves to create mathematically reconstructed images.
Originally known as Nuclear Magnetic Resonance.

Strengths of MRI

Offers exceptional low contrast resolution.
This is its main advantage due to the small difference in X-ray attenuation coefficients within soft tissues.
Provides clear visualization of structures without the need for contrast media.
Capable of resolving relatively small contrast differences between tissues.

Contrast Dependence

Contrast in MRI images is determined by the interaction of matter with electromagnetic forces.

Conventional Imaging

Produces "flat" images where structures are superimposed.
Requires contrast media to distinguish between anatomical structures.
