Medical Imaging Seminar Series

Speaker: Dr. Vidya Rajagopalan, Children’s Hospital Los Angeles

Abstract: Historically, human in vivo fetal brain growth studies have been limited to manual measurements, such as diameters and volume, of the entire brain or fetal head from ultrasound and 2D MR images. However, the formation of complex folded cortical structure of the adult brain requires that tissue volume is added at different rates within different brain regions. Recent advances in fetal MRI motion correction and preprocessing methods present an unprecedented opportunity to characterize fetal brain
development as a function of both age and location within the brain. In this talk, we will discuss computational shape analysis techniques to model spatio-temporal patterns in
age-related development of normal fetal brains. We discuss how these models can be used to understand the emergence of cortical foldings and structural asymmetries of the fetal brain. We also present a comparative analysis of growth rates of various brain
structures allowing us to understand the similarities and differences between regional growth trajectories. These growth models allow us to develop a baseline of developmental biomarkers with which to correlate abnormal development.
