Study Notes
Magnetic Resonance Imaging (MRI)
- The basis for MRI imaging is the interaction between nuclear magnetic moments and an external magnetic field.
History of MRI
- MRI was initially called Nuclear Magnetic Resonance (NMR) imaging.
- The first MRI exam was performed on a human being in 1977.
Key Factors in MRI
- The key factor in MRI imaging is the magnetic properties of hydrogen nuclei (protons) in the body.
- The primary reason for the net magnetic field of protons in the body being zero is that the magnetic moments of the protons are randomly aligned.
- The magnetic field in protons is created by the spin of the proton.
- The main principle behind the interaction of protons with an external magnetic field is that the protons align either parallel or anti-parallel to the external magnetic field, depending on the strength of the field.
