Towards Robust Radiomic Markers from Positron Emission Tomography in Cancer
[18F]-fluorodeoxyglucose positron emission tomography ([18F]-FDG PET) images contain both rich and untapped information regarding diseases such as cancer. The latter can be accessed computationally using radiomics, from which we can build new markers of disease to improve the clinical management of …

Improving Quantitative Treatment Response Monitoring With Deformable Image Registration
Quantitative imaging with 18F-FDG PET/CT has the potential to provide an in vivo assessment of response to radiotherapy (RT). However, comparing tissue tracer uptake in longitudinal studies is often confounded by variations in patient setup and potential treatment induced gross anatomic changes. …
