Paper published in Clinical and Translational Radiation Oncology

In our paper “Cleaning Radiotherapy Contours for Radiomics Studies, is it Worth it? A Head and Neck Cancer Study“, published in ctRO (Elsevier), we study the benefit of delineating tumor contours specifically for radiomics analyses (automatic prognostic prediction of patients with Head and Neck cancer). The contours originating from radiotherapy often include parts of surrounding organs (e.g. trachea, bones) which impact the extraction of visual features that characterize the tumor.

Example of VOI delineation: Radiotherapy (green), Resegmented (purple), and Dedicated (blue) overlayed on a fused FDG-PET/CT image. The blue contour is closer to the true volume of the primary tumor.
