Biography

Takeshi Yokoo, M.D., Ph.D., is an Associate Professor of Radiology at UT Southwestern Medical Center and a member of its Body Magnetic Resonance Imaging (MRI) Division. He also serves as Medical Director of MRI for University Hospitals and Clinics, and chief of MRI for Parkland Memorial Hospital's Department of Radiology. His clinical interests include imaging of liver cancer and chronic liver disease.

Dr. Yokoo holds a bachelor's degree in mathematics from Williams College in Williamstown, Massachusetts. He earned his doctorate in biomathematics and his medical degree at Mount Sinai School of Medicine in New York. He then completed his residency in diagnostic radiology on a five-year research track at the University of California, San Diego before obtaining advanced training in abdominal imaging and intervention through a fellowship at Massachusetts General Hospital in Boston.

A passion for research

Dr. Yokoo focuses on researching quantitative imaging techniques in order to support radiologists in objective interpretation and standardized reporting of imaging studies. He has collaborated with MRI manufacturers to develop product sequences that are now available for routine clinical imaging use. Through his extensive research and work in technological imaging advancement, along with his research on topics such as diffuse liver disease and liver cancer, Dr. Yokoo has authored or co-authored more than 50 peer-reviewed publications.  

A career marked by service

In addition to serving on numerous committees for the UTSW Radiology Department, Dr. Yokoo is an active member of several national and international professional societies, including the American College of Radiology, the Society of Abdominal Radiology, the Radiological Society of North America, the American Board of Radiology, and the International Society of Magnetic Resonance in Medicine

He is an active reviewer for the Journal of Magnetic Resonance Imaging and Magnetic Resonance in Medicine; for the latter, he has been recognized as a distinguished reviewer five timesIn addition, he has served as an ad hoc reviewer on a range of publications such as Abdominal ImagingJournal of Hematology, and European Radiology. He also served as a guest editor for a special issue of BioMed Research International focused on "Advances in MR Imaging Techniques and Applications.”
