Billy W. Loo Jr., MD Ph.D. is a Professor of Radiation Oncology, a member of the Stanford Cancer Institute, a member of the Molecular Imaging Program at Stanford (MIPS) in the Department of Radiology, and a member of Bio-X in the School of Medicine. He is a physician-scientist Radiation Oncologist and Bioengineer who directs the Thoracic Radiation Oncology Program at Stanford.
His clinical specialties are state-of-the-art radiation therapy for lung/thoracic cancers, including stereotactic ablative radiotherapy (SABR) and 4-D image-guided radiation therapy for lung tumors. Dr. Loo is a recognized expert in thoracic cancers serving on multiple national committees (including as writing member, chair, or vice-chair) that publish clinical guidelines on the treatment of lung cancer and other thoracic malignancies, particularly the National Comprehensive Cancer Network (NCCN).
His clinical research is in clinical trials and implementation of new treatment techniques for lung cancer, and the development of new medical imaging methods for measuring organ function and predicting response to cancer treatment. As part of this work, he leads a clinical and preclinical research program in molecular imaging, particularly using novel PET tracers for tumor hypoxia (EF5), tumor proliferation (FLT), and neuroinflammation (PBR06). He also co-leads clinical trials of novel applications of SABR including the treatment of pulmonary emphysema and cardiac arrhythmias.
Dr. Loo received his MD from the University of California, Davis, and his Ph.D. in Bioengineering from the University of California, San Francisco, and Berkeley. He completed his Radiation Oncology residency training at Stanford University. He is certified by the American Board of Radiology in Radiation Oncology and is a Fellow of the American Society for Radiation Oncology (ASTRO) and a Fellow of the American College of Radiology (ACR).
