Gradient performance tumor characterization at Vanderbilt University Institute of Imaging Science

At a glance

 
  • Hear how Vanderbilt is able to detect change in tumor morphology to provide a much earlier response
  • See how a technology is used that provides cell size, cell density and membrane permeability information to know the exact response of cancer cells to distinguish recurring brain tumors from radiation induced injuries

Dr. Junzhong Xu, Director of Cancer Imaging Research at the Vanderbilt University Institute of Imaging Science discusses the development of MR cell size imaging [1] utilizing diffusion MRI. The imaging technique provides real-time data on cell size, density and membrane permeability and gradient strength is crucial for accurate measurements. The technology's ability to differentiate recurrent brain tumors from radiation injuries and track cell changes associated with chemotherapy-induced apoptosis is groundbreaking.

“Our ability to detect accurate mean cell size in tumors relies on the gradient strength we have. The stronger gradients we have, the more accurate and reliable measurements we can make. We will develop and validate a more advanced technology to evaluate tumors more comprehensively.”
