Ruth Lim

Ruth Lim, MD is an Assistant Professor of Radiology & Biomedical Imaging at Yale School of Medicine. She is affiliated with the Center for Molecular Imaging Technology and Translation (CMITT), Clinical Radiology, Pediatric Radiology, and the Yale Biomedical Imaging Institute. Her primary research focuses on medical imaging applications in oncology, nuclear medicine, and pediatric radiology. Dr. Lim earned her MD from the University of Toronto in 1999 and is board-certified in Nuclear Medicine.

Her research interests include PET imaging of soft tissue sarcomas, radiation oncology protocols, and development of imaging guidelines for pediatric cancers. She collaborates extensively with teams in artificial intelligence-driven medical image analysis and radiation dosimetry.

Dr. Lim's recent work emphasizes improving diagnostic accuracy through advanced imaging techniques, including diffusion models for tumor volume prediction and AI-based segmentation tools. She contributed to guidelines for pediatric glioma imaging and renal scintigraphy standards. Her studies span clinical outcomes of chemoradiation therapies and applications of deep learning in radiology.

She holds no explicitly stated awards but has authored/co-authored over 20 peer-reviewed publications since 2020. Her work is supported by collaborations with institutions like the Children's Oncology Group and NRG Oncology.

Dr. Lim participates in translational research initiatives at Yale, focusing on integrating molecular imaging with clinical decision-making. She mentors trainees in radiology and biomedical imaging through Yale's academic programs.
