Summary
Clinical applications of functional magnetic resonance imaging (fMRI) are expanding, integrating techniques like BOLD-fMRI and ASL-fMRI with other neuroimaging methods to aid diagnosis and treatment planning for various neurological conditions.
Area of Science:
- Neuroimaging
- Clinical Neuroscience
Background:
- Functional magnetic resonance imaging (fMRI) is a prevalent research tool with limited clinical diagnostic and treatment planning applications.
- Evidence-based data on clinical fMRI utility and decision-making remains sparse.
Purpose of the Study:
- To provide an overview of clinical fMRI applications using illustrative examples.
- To highlight strategies, benefits, and challenges in analyzing diagnostic fMRI studies for individual patients.
Main Methods:
- Integration of blood oxygenation level dependent (BOLD)-fMRI and arterial spin labeling (ASL)-fMRI with perfusion measurements, electroencephalography (EEG), diffusion-weighted imaging (DWI), and fiber tractography.
- Case-based examples of clinical fMRI implementation.
Main Results:
- fMRI, particularly when combined with other modalities, can assist in clinical decision-making.
- Specific challenges exist for fMRI in patients with brain tumors, space-occupying lesions, cortical dysplasias, seizure disorders, and vascular malformations.
Conclusions:
- Clinical fMRI shows promise for enhancing diagnostic accuracy and treatment planning in complex neurological cases.
- Careful analysis and interpretation strategies are crucial for maximizing the clinical value of fMRI.
