报告人简介
Jaladhar Neelavalli has been focusing on developing methods to improve quantitative susceptibility mapping (QSM/SWIM) and post processing methods for susceptibility weighted imaging (SWI). Specifically, he is interested in developing these methods for quantification of venous oxygen-saturation changes in normal versus abnormal clinical conditions. He is now modifying and applying these methodologies to fetal MR imaging with a view to study what changes in the vascular development and oxygen utilization in the developing brain in-utero in normal versus high-risk pregnancies. Dr. Neelavalli has a strong background in MR physics and fetal imaging.

报告简介
Fetal growth restriction occurs in 16% of pregnancies worldwide where insufficient nutrient supply along with hypoxemia is often implicated. The condition is associated with both short and longterm neurological sequelae. MR imaging is an excellent tool for quantitative imaging that can help us better understand the in-vivo physiology. This talk would discuss the technical challenges in quantitative MR imaging of the human fetus with specific focus on blood-oximetry, phase contrast imaging and MR angiography. Some of the recent approaches attempting to address these issues and the quantitative results from these methods will be presented.
