It’s good news: Our team won PET segmentation challenge using a data management and processing infrastructure!

Automated segmentation of PET images for the delineation of tumor volumes has been the focus of intense research efforts for the last few years. There has also been a few limited efforts to compare several methods on common datasets, but in the majority of cases, each method has been evaluated on different image sets according to different evaluation criteria, and a comparison of currently available methods based on literature analysis only is thus challenging, if not impossible. A MICCAI challenge is an interesting opportunity to compare numerous existing methods implemented by their original authors (thus avoiding issues associated with re-implementation of methods by others) on a common set of images. This challenge will be organized and funded by France Life Imaging, a national French infrastructure dedicated to medical imaging sciences, and co-sponsored by the taskgroup 211 “Classification, Advantages and Limitations of the Auto-Segmentation Approaches for PET” of the American Association of Physicists in Medicine (AAPM), following in particular the recommendations it has set regarding benchmarking efforts (choice of image datasets and evaluation strategies).
