Radiomic Feature
Quantitative imaging characteristic extracted from medical images using computational analysis methods.
Full Definition
Radiomic features represent quantitative characteristics extracted from medical images using advanced computational methods, capturing information about tumor shape, intensity, texture, and higher-order statistical properties that may not be visible to the human eye. These features can include first-order statistics, shape-based features, gray-level co-occurrence matrix parameters, and wavelet-based features. Radiomics analysis aims to correlate these quantitative imaging biomarkers with clinical outcomes, treatment response, and molecular tumor characteristics, potentially enabling personalized medicine approaches.
