Introduction

Advanced Imaging in Pediatric Neurodevelopment

Human neurodevelopment is an incredibly complex and incompletely understood process, with sequential events beginning in the embryonic/fetal period and continuing throughout infancy, childhood, and adolescence. Characteristic changes at each stage of life are reflected by progression through successive neurologic and psychosocial milestones. This coordinated maturation occurs despite rapid fluctuations in growth and metabolism, highlighting … more »

In 2011, we began our investigation into the detection of microstructural changes that occur in both the white matter (WM) and gray matter (GM) of the developing pediatric brain using an MRI diffusion technique called diffusional kurtosis imaging (DKI). This technique is an … more »

My interest in the use of diffusion tensor imaging to diagnose spinal cord injury was spurred by a casual conversation over dinner with Dr. M.J. Mulcahey (who went on to become my collaborator) regarding her work on children with spinal cord injury. During this conversation, I was moved to learn about the heartbreaking … more »

Gray Matter Growth Is Accompanied by Increasing Blood Flow and Decreasing Apparent Diffusion Coefficient during Childhood

Nils Daniel Forkert

Children, especially within the first few years of development, experience rapid and considerable changes of the macro- and microstructure of the brain. These changes include rapid growth of the brain tissue, myelination patterns and white matter connectivity alterations, and cerebral blood flow changes. Although age-related alterations of the corresponding imaging biomarkers are well-described … more »

Our research interests focus on developing leading-edge, noninvasive MRI tools that are capable of identifying early warning signs of a fetus who is at risk for brain injury before that injury is consolidated. The long-term goal of our research is to translate these tools rapidly into clinical practice and develop early MR imaging biomarkers … more »

The human brain develops at an incredible rate during the first several years of life. During this period, the brain is extremely plastic as it is vulnerable. My technical team complements the efforts of the clinical team led by Drs. Jim Barkovich and Donna Ferriero to leverage imaging in order to improve diagnosis and … more »
