Radiomics and data analytic methods applied to cardiac imaging

Technique	Definition175–177
Radiomics	Process by which quantitative features describing the texture and spatial complexity of the tissue are extracted from CT images.
Machine learning	Sub-division of artificial intelligence, which uses computer algorithms to learn from data analysis, without being programmed for that specific task. Differently from conventional multivariable analysis based on probability theory, it derives pure statistical models to detect non-linear relationships between a large number of potential predictor variables.
Deep learning	Sub-division of machine learning, which uses deep neural networks to solve difficult problems.

CT, computed tomography.
