Questions and Answers

Water has more protons bonded to a long chain of carbon framework compared to fat.

False

The shielding effect is stronger in water than in fat, causing the protons in water to experience a lower magnetic field.

False

At 1.5 Tesla, the resonance frequency of hydrogen molecules in water is approximately 64 MHz.

True

The resonance frequency of hydrogen molecules in fat at 1.5 Tesla is exactly 63.87 MHz.
