Oncologists have great expectations of new ways to quantify a tumor’s response to treatment (and better assess the effectiveness of cancer therapies). Functional imaging, whereby a tumor’s activity (metabolism, blood flow, diffusion characteristics, etc.) is investigated rather than its size, is a promising approach to do so. Yet, while the potential of functional imaging in the domain of oncology may be great, using it in clinical practice hinges on over- coming some important limitations.
During the FIAT project, a consortium of researchers and industry partners (both from the hardware and the soft- ware side) explored the potential of several functional image modalities to quantify tumors more accurately. They did so by setting up two parallel research tracks (i.e. small animal as well as clinical imaging), using the research outcomes of both paths to reinforce one another. Particular attention was paid to computed tomography (CT) perfusion imaging, and the quantification of positron emission tomography (PET) for small animal imaging.
