Dr. Yoo is a paediatric cardiac radiologist. He is a Professor of the Departments of Medical Imaging and Paediatrics at the University of Toronto. His main clinical and research activities are Magnetic Resonance (MR) and Computerized Tomography (CT) applications in children with cardiovascular disease and fetal echocardiography. He is an early adopter of hemodynamic assessment of congenital heart diseases using MRI and 3D printing in paediatric cardiology and surgery. Using 3D printed or silicone-molded heart models, with his colleague cardiovascular surgeons, Dr. Yoo leads the Hands-On Surgical Training (HOST) Course for congenital heart surgery at both SickKids and worldwide since 2015.
Dr. Yoo's research is focussed on pragmatic utilization of newly-developing imaging technologies and concepts. They include functional/hemodynamic assessment of paediatric heart diseases using MRI, and 3D imaging for surgical planning and training for congenital heart surgery. He envisions current computer screen-based imaging reporting systems will be replaced by space-based reporting systems using virtual, augmented and mixed reality.
