    • Neuroimaging

    Dr. Poskitt's clinical and academic focus has centered around neuro-imaging of the developing brain. Acquired brain injuries from insults such as infection birth asphyxia, trauma and congenital heart defects are studied to understand the impact on brain development and neurological outcome. As a member of CFRI, Dr. Poskitt participates in primary research in collaboration with other members of the Developmental Neurosciences & Child Health group. His other mandate from CFRI is to make himself and his knowledge of imaging techniques available to any CFRI Researcher whose project might be advanced by including an imaging component to the study design. Dr. Poskitt is also playing an instrumental role in the development of the 3T Imaging Research Facility to be built at Children's & Women's.

    Current Projects

    In conjunction with Dr. Steven Miller long term studies on the impact of neuro-development in two at risk groups have been initiated: premature infants and infants born with congenital heart defects.  These studies entail a large component of serial MR imaging to detect injury but also apply more advanced MR imaging techniques such as DTI imaging and MR spectoscopy in an effort to quantify the effects of different variables on the development, structure and function on the infant brain.  These techniques have been applied on identified fetuses know to be at risk as well as other cohorts suffering from some form of acquired brain injury such as those that accompany chronic renal disease or radiation and chemotherapy in patients suffering from brain tumors.

    A second group of subjects that have been the focus of extensive long term investigation are infants born who are at risk of brain injury secondary to Hypoxic ischemic encephalopathy at the time of delivery.  The neonatal neurology group at BCCH has a 20-year history of working with imaging, both CT and MRI, to outline the imaging correlates of different types of birth asphyxia.  Most recently efforts have been undertaken to study the utility of early, (between 12 and 24 hours), diffusion weighted imaging, FA maps and MR spectroscopy in the identification and stratification of brain injury.  These studies have entailed serial MR imaging without sedation of infants at risk.  More recent efforts have been made to expand this group by developing a working partnership with Children's National Medical Center in Washington, DC.
