Functional MRI (FMRI)Functional MRI (fMRI): Uses, Process, Benefits and Limitations
Frequently Asked Questions
With cutting-edge imaging methods like Functional Magnetic Resonance Imaging (fMRI), neuroscience has recently made incredible gains in comprehending the complexity of the human brain.
Functional MRI is used for the following:
- Brain mapping
- Diagnosis and treatment planning
- Cognitive studies
- Drug development
Using an fMRI has the following benefits:
- Non-invasiveness – fMRI is non-invasive, meaning it doesn’t require any injections or surgical procedures, unlike other brain imaging methods that might need them.
- High Spatial Resolution – Because fMRI has a great spatial resolution, researchers can identify the precise brain areas engaged during particular tasks.
- Versatility – It’s a flexible tool for neuroscience research because it may be used to examine various cognitive processes and brain functions.
The following limitations and drawbacks exist to fMRI:
- Expensive equipment – Because fMRI needs specialized and pricey equipment, its use in some hospitals and research facilities may be constrained.
- Indirect measure – FMRI measures blood flow changes and is a proximate indicator of brain activity.
- Motion artifacts – Results can be distorted and artifacts introduced even by slight movements made during the fMRI scan.
- Limited temporal resolution – Even though fMRI has good spatial resolution, it has poor temporal resolution compared to other methods like EEG, which can precisely record brain activity in milliseconds.
