radiomics
High-throughput extraction and analysis of quantitative features from medical images.
Full Definition
Radiomics is an emerging field that involves the extraction of large amounts of quantitative features from medical images using computational algorithms. These features, which are not visible to the human eye, include texture, shape, and intensity characteristics that can be correlated with clinical outcomes, treatment response, or disease prognosis. In neuroimaging, radiomics approaches are increasingly used to identify imaging biomarkers for neurological diseases, predict treatment responses, and support precision medicine initiatives. The field bridges medical imaging, computer science, and clinical medicine to transform images into mineable data.
Usage
Usage note: Often confused with 'radiogenomics' which specifically correlates imaging with genomic data.
