Neuroimaging is a set of tools that produce pictures, of the brain, also known as brainscans, and is extremely important for humans’ understanding of the nervous systemThere are currently two types of neuroimaging, structural and functional. Structuralimaging creates a picture of the inside of the head, which includes bone, brain tissue,blood vessels, and fluid of the brain and spine (cerebrospinal fluid), while functionalimaging looks at the brain’s activity by measuring blood flow, electrical impulses, orchemical activity (DNA Learning Center).According to Santosh (2000) neuroimaging in child psychiatry is a rapidlydeveloping field and the number of different techniques being used is increasingrapidly.When taking part in neuroimaging research, the age of the pediatric participanttaking part should strongly influence the research protocol for pediatric imaging.

The key to efficient and appropriate neuroimaging in children and adolescents isunderstanding the role imaging plays and what the limitations are. Computed Tomography (CT)utilizes radiation and should be reserved for children and adolescents for emergency evaluationand potentially catastrophic injury resulting from: “stroke, herniation, hemorrhage, hematoma,intracranial masses, increased intracranial pressure, or acute skull fracture” (O’Malley, Richer,and Strawn, 2016). For children and adolescents, there has been recognition of the limit ofexposure to radiation. As a result, most providers agree that Magnetic Resonance Imaging (MRI)should be used instead of CT, when appropriate. Especially since over the past several decades,MRI is increasingly available in most settings that are available to children and adolescents. MRIhas advantages over CT and includes: “better spatial resolution, assessing multiple pathologicalprocesses, lack of exposure to radiation” (O’Malley, Richer, and Strawn, 2016). Children andadolescents with ADHD may not need neuroimaging (O’Malley, Richer, and Strawn, 2016).
