Researchers pioneer molecular imaging agents to individualize cancer therapy

“Our ability to use PET imaging to identify patients with tumors at high risk for treatment failure, those who are experiencing treatment failure, and those individuals for whom an ideal targeted therapy will have an immediate and direct positive clinical impact,”  said Eary, co-principal investigator in the study and a UW professor of nuclear medicine. “Most of the imaging agents we have pioneered are now used around the world and are involved in numerous multi-center clinical trials.”

Other researchers on the project are Jeanne Link, a UW associate professor of nuclear medicine, and David Mankoff, a UW professor of radiology. By showing the chemical reactions actually taking place inside a person’s body, nuclear medicine imaging has the benefit of characterizing the cancer disease within an individual patient.   At the very heart of this research project is the collaborative teamwork that takes place between the laboratory scientists and the clinicians.

The UW PET Cancer Group has been actively investigating new imaging agents for more than 20 years.  Their work encompasses development of imaging agents, pre-clinical models, and translation to early phase clinical trials.  The group consists of radiochemists, clinical imaging specialists, imaging physicists and image analyses experts who interact in a multidisciplinary environment.
