OC-0415: The effect of breathing motion on CT radiomics feature extraction in oesophageal cancer
Data from: 4DCT imaging to assess radiomics feature stability: an investigation for thoracic cancers
Background and Purpose
Quantitative tissue characteristics derived from medical images, also called radiomics, contain valuable prognostic information in several tumour-sites. The large number of features available increases the risk of overfitting. Typically test-retest CT-scans are used to reduce dimensionality and select robust features. However, these scans are not always available. We propose to use different phases of respiratory-correlated 4D CT-scans (4DCT) as alternative.Â
