A brain-imaging method using magnetic fields to measure the spinning of hydrogen atoms in the brain is called
A) electroencephalography (EEG).
B) magnetic resonance imaging (MRI).
C) positron emission tomography (PET).
D) computed tomography (CT).
Answer: B
Rationale: Magnetic resonance imaging (MRI) uses a giant magnetic field to align and spin hydrogen atoms in the same direction. Radio waves are then passed through the brain, disrupting the alignment of the atoms. These disruptions produce a signal that can be translated into a detailed, 3-dimensional image of the brain.
