Arasu, Vignesh

Vignesh A. Arasu, MD, PhD, is a Research Scientist with the Kaiser Permanente Northern California Division of Research. He is also a practicing radiologist subspecializing in breast imaging at Kaiser Permanente Vallejo Medical Center.

Dr. Arasu conducts research at the intersection of medical imaging, breast cancer, and artificial intelligence (AI). As an embedded clinician researcher, he evaluates priority operational issues in breast cancer medical imaging to accelerate implementation and innovation. As a research principal investigator, he oversees two randomized trials investigating the use of AI for breast cancer screening.

Dr. Arasu earned his medical degree and completed his radiology residency and fellowship at the University of California, San Francisco (UCSF). He also holds a PhD in Epidemiology and Translational Science from UCSF.

Current Positions

Primary Research Interests

  • Breast cancer
  • Medical imaging
  • Risk-based screening
  • Artificial intelligence and computer vision deep learning

Studies

Grasshopper: A Novel Clinical Dashboard for Radiologists

The primary goal of this project is to evaluate differences in radiology reporting specificity when radiologists use a novel dashboard that surfaces pertinent clinical information at the time of image interpretation. Secondary goals include the evaluation of downstream clinical impact of reporting specificity, including but not limited to decreased utilization of prescription medications and follow-up imaging.

Investigator: Arasu, Vignesh
