The brain imaging technique that tracks blood flow in the brain using magnetic fields is _____.
A) fMRI
B) ablation
C) ERP
D) PET scan

Question

Quizplus · Accepted Answer

Magnetic fields are used to track blood flow in the brain in functional magnetic resonance imaging (fMRI). Ablation involves the removal or destruction of tissue, ERP (event-related potentials) measures electrical activity in the brain, and PET (positron emission tomography) scans involve injecting a radioactive substance and tracking its movement in the brain. Therefore, fMRI is the correct choice for tracking blood flow in the brain using magnetic fields.
