Functional magnetic resonance imaging

Area of Science:

• Neuroscience
• Pediatric Neurology
• Medical Imaging

Background:

• Functional MRI (fMRI) is a key tool for assessing neurodevelopmental disorders, capable of detecting functional brain network alterations.
• The clinical impact and added value of fMRI in pediatric neurodevelopmental assessments remain debated.

Purpose of the Study:

• To provide an overview of task-based and resting-state fMRI applications in children with neurodevelopmental disorders.
• To introduce promising analysis methods like PPI and machine learning.
• To discuss the strengths and limitations of fMRI in pediatric clinical settings.

Main Methods:

• Review of task-based and resting-state fMRI studies in pediatric neurodevelopmental disorders.
• Introduction of advanced analysis techniques such as psycho-physiological interaction (PPI) and machine learning.
• Discussion of clinical utility, strengths, and limitations.

Main Results:

• fMRI has enhanced understanding of developmental conditions, informing neuroanatomical models and revealing compensatory mechanisms.
• Improvements have made fMRI more child-friendly.
• Group studies provide unique insights into brain function in conditions like dyslexia, DLD, and epilepsy.

Conclusions:

• fMRI offers valuable insights into neurodevelopmental disorders but faces challenges in clinical application.
• Limitations include lack of result replication, limited diagnostic specificity, and interpretation difficulties.
• Current clinical use is restricted, primarily to epilepsy surgery planning.
