Radiomics enables the extraction of quantitative features from medical images, potentially augmenting the characterization of healthy and diseased tissue. Before these features can be routinely used as biomarkers in clinical practice, however, their repeatability and reproducibility must be ensured. This study seeks to investigate feature repeatability in an in-vivo, clinical test-retest dataset of prostate cancer patients. Our results show that the majority (71.8%) of radiomic features extracted from in-vivo, clinical T2-weighted images was not repeatable, emphasizing the need for repeatability and reproducibility studies.
