none of the answers in this list of options fills the blank. Strong magnetic fields created by the powerful magnets used in MRIs compel the body's protons to align with the field.
- The protons are activated and spin out of equilibrium when a radiofrequency current is then pulsed through the patient, struggling against the magnetic field's pull.
- Because protons can spin either left or right, which corresponds to a distinct energy state, they have multiple spin configurations.
- Higher energy states are experienced by protons that align against the external magnetic field as opposed to lower energy states experienced by protons that do so.
- The hydrogen protons will align themselves once more with the static magnetic field once the energy from the RF pulse is lost.
- Hydrogen protons serve as the source of the MRI signal since they move back into alignment with the magnetic field, and fall out of "phase" with each other.
