Yuntong (Lorin) Ma, MD, MPhil is an Assistant Professor, Clinical Radiology at the San Francisco VA Medical Center.

Dr. Ma earned her medical degree at Washington University School of Medicine in St Louis, followed by internship at Santa Clara Valley Medical Center in San Jose, CA. Dr. Ma completed diagnostic radiology residency at Brigham and Women’s Hospital in Boston where she was a clinical fellow at Harvard Medical School. In 2023, Dr. Ma completed her fellowship in musculoskeletal imaging at Stanford, where she was also a clinical scholar. Dr. Ma holds an MPhil in Sociology from St. John’s College, Cambridge University, where she was a Gates Cambridge Scholar conducting research on the socio-ethical implications of emerging technologies, using the CRISPR-Cas9 genome editing system as a case study.

During residency, Dr. Ma’s research examined the role of radiologic-pathologic correlation for decision-making after non-diagnostic CT-guided lung biopsies and investigated the diagnostic accuracy of pelvic radiographs for the detection of traumatic pelvic fractures in the elderly. In her final year of residency, Dr. Ma participated in the Mass General Brigham Data Science Office (DSO) Data Science Pathway (DSP) to learn the fundamentals of artificial intelligence and machine learning in healthcare, and through this work developed a deep learning algorithm to differentiate rheumatoid arthritis from osteoarthritis on hand radiography. This work received the Senior Research Award for Dr. Ma’s presentation on “Deep learning discrimination of rheumatoid arthritis from osteoarthritis on hand radiography.”

As an educator, Dr. Ma co-authored the MSK chapter of the second edition of the widely used Core Radiology.
