Noninvasive imaging of immune system detects tumors, could monitor therapeutic response

April 20, 2015

A novel approach that allows real-time imaging of the immune system's response to the presence of tumors—without the need for blood draws or invasive biopsies—offers a potential breakthrough both in diagnostics and in the ability to monitor efficacy of cancer therapies.

The method, developed in the lab of Whitehead Institute Member Hidde Ploegh and reported online this week in the Proceedings of the National Academy of Sciences (PNAS), harnesses the imaging power of (PET), which is normally used to monitor cancer metabolism, to identify areas of immune cell activity associated with inflammation or .
