Question

Describe in a sentence one advantage that functional magnetic resonance imaging (fMRI) has over positron emission tomography (PET).

A) fMRI provides information about brain structure, while PET provides information about brain function.
B) fMRI uses radioactive tracers, while PET uses magnetic fields.
C) fMRI allows for real-time imaging, while PET has higher spatial resolution.
D) fMRI does not involve ionizing radiation, while PET exposes the patient to radiation.

Answer 1

fMRI provides information about brain structure, while PET provides information about brain function.

Step-by-step explanation:

An advantage that functional magnetic resonance imaging (fMRI) has over positron emission tomography (PET) is that fMRI provides information about brain structure, while PET provides information about brain function. While fMRI shows detailed images of the brain's structure and provides accuracy in time, PET scans only show a rough map of active and inactive areas of the brain during a specific behavior. Therefore, fMRI is more useful in studying the structural aspects of the brain, while PET is more focused on understanding brain function.
