radiomics
Pronunciation: RAY-dee-oh-miks
High-throughput extraction of quantitative imaging features for predictive modeling.
Full Definition
Radiomics is an emerging field that involves the high-throughput extraction and analysis of large numbers of quantitative features from medical images to develop predictive and prognostic models. Unlike traditional imaging assessment that relies on visual interpretation, radiomics uses computational methods to extract hundreds or thousands of mathematical descriptors characterizing tumor shape, intensity, texture, and spatial relationships. These features can capture subtle patterns invisible to the human eye and may correlate with tumor biology, treatment response, and patient outcomes. Radiomics applications in oncology include predicting treatment response, assessing tumor aggressiveness, and identifying patients at risk for recurrence or complications.
Usage
Usage note: Distinguish from radiogenomics, which correlates imaging with genomic data.
