Brief Biography

Dr. Yoo is a cardiac radiologist and leads the Division of Cardiac Imaging. He is a professor of the Departments of Medical Imaging and Paediatrics at the University of Toronto. His main clinical and research activities are MR and CT applications in children with cardiovascular disease and fetal echocardiography. He has developed a unique training program for cardiac imaging where both radiology and cardiology fellows collaborate closely together in a harmonious and productive manner.  Recently he has introduced 3D printing or rapid prototyping technology to the program.  This technique allows preoperative simulation of the surgical procedures in patients with complex congenital heart disease. 

Research Interests

• Cardiovascular MRI and Fetal Echocardiography in Children

Research Activities 

• Clinical research in MRI assessment of pulmonary circulation
• Clinical research in MRI assessment of right ventricular function
• MR evaluation of pulmonary and abdominal circulation after single ventricle repair
• 3D plastic printing of cardiovascular model from MRI or CT image data

Future Research Interests

• MRI assessment of vascular physiology
• Establishment of an image data archive of congenital heart diseases

Clinical Care Activities

• Cardiovascular MRI
• Cardiovascular CT
• Plain radiography
• Fetal echocardiography
