Despite an increase in the use of structural and functional magnetic resonance imaging (fMRI) in humans, the study of young pediatric populations remains a challenge. We present a hands-on, step-by-step video protocol including guidelines for clinicians and researchers intending to perform (f)MRI in young children.

Toddler and Preschool Child Exam

Source: Heather Collette and Jaideep Talwalkar; Yale School of Medicine The key to a successful exam of a toddler or preschool-age child is building rapport and trust between them and the provider. Toddlers, in particular, may be wary of strangers and unwilling to cooperate with the physical exam, which is expected age-appropriate behavior. In order to provide good care and create a comfortable patient experience, clinicians need to tailor their interaction to the child's developmental stage.

Here, we present a protocol that provoked cortisol reactivity in a vulnerable adolescent Mexican American sample utilizing a modified version of the Trier Social Stress Test (TSST). Saliva samples were collected at baseline, 15, 30, and 45 min post-TSST onset. Future research could utilize this modified TSST with vulnerable youth.

Source: Heather Collette and Jaideep Talwalkar; Yale School of Medicine The adolescent module will focus on techniques to promote a trusting provider-patient relationship and foster healthcare autonomy as teenagers approach adulthood. While most of the basic components of the physical exam in adolescents are similar to those in adults, there is an added focus on pubertal development through the use of the Sexual Maturity Rating scale. Important adolescent psychosocial screening questions,...

This protocol describes the steps and data analysis required to successfully perform optogenetic functional magnetic resonance imaging (ofMRI). ofMRI is a novel technique that combines high-field fMRI readout with optogenetic stimulation, allowing for cell type-specific mapping of functional neural circuits and their dynamics across the whole living brain.
FAQs
The strong magnetic field aligns hydrogen nuclei in brain tissue. Radiofrequency pulses briefly disturb that alignment, and the nuclei emit signals as they return toward their original state. The imaging system converts differences in these signals into structural images, allowing researchers to examine developing brain anatomy without invasive procedures.
Functional MRI measures changes in blood oxygenation rather than focusing only on brain structure. Researchers can collect these signals while a child or adolescent performs a task or while the participant rests. Comparing functional patterns with behavior can provide information about neural activity associated with attention, emotion, learning, social behavior, and cognition.
Head motion can reduce the quality and interpretability of MRI data, particularly when participants are young. Age-appropriate protocols and strategies designed to reduce movement help produce more reliable images and functional measurements. Better data quality strengthens conclusions about relationships between brain development and behavioral characteristics.
Protocols should be adapted to the participant’s age and designed to support data quality. Researchers must account for the demands of imaging the developing brain and use approaches that reduce head motion. These considerations make it more feasible to study participants across developmental stages and compare brain-behavior relationships.
MRI-based research can relate developing-brain measures to several behavioral domains, including attention, emotion, learning, social behavior, and cognition. Structural images contribute information about brain development, while functional measurements from tasks or rest can add information about blood-oxygenation changes associated with these domains.
Researchers can use child and adolescent MRI to examine how brain characteristics relate to behavior during typical development and in neurodevelopmental conditions. The approach supports comparisons between developmental patterns and behavioral features, while age-appropriate procedures and improved motion control help make those comparisons more scientifically informative.
