Study Notes

MRI Applications

Hydrogen atoms are chosen for MRI applications due to their high abundance in the body, particularly in water and fat molecules, making them an ideal target for magnetic resonance imaging.

Atomic Structure of Hydrogen

A hydrogen atom consists of one proton in its nucleus and one electron orbiting around it.

Hydrogen Spins in Human Body Tissues

In the human body, the spins of hydrogen atoms are randomly aligned, resulting in no net magnetic field.

Net Magnetization in the Human Body

Without an external magnetic field, the net magnetization in the human body is zero due to the random alignment of hydrogen spins.

Hydrogen Protons in a Strong Magnetic Field

When a person is placed under a strong magnetic field, the hydrogen protons in the body align either parallel or anti-parallel to the magnetic field, resulting in a net magnetization.
