“…Conventionally, radiomic features determine a single scalar value to define a complete three-dimensional (3D) tumour volume; however, more recent research uses pixel-based features generating many values per feature for a 3D tumour volume [19]. These features can then be fed into a classifier to determine the features which have the strongest correlation with outcomes.…”

“…Radiomics are imaging features that have been extracted from radiological data such as CT, MRI, nuclear medicine images, single photon emission computed tomography (SPECT) and PET data. 8 , 9 , 10 Traditionally in nuclear medicine, radiomics were extracted using hand‐crafted regions of interest (ROIs) or manually drawn ROIs as they are also referred to. Examples include the ROI for the left ventricle (LV) to determine the ejection fraction (EF) that required hand‐crafted regions around the ventricle for each of the gated bins.…”

“…While radiomics aim for higher dimensional data extraction and representation, radiomics can be classified into tiers or orders 8 , 9 , 10 : First‐order or primary radiomics capture the spatial characteristics of signal intensity such as size, shape and count density. Second‐order or secondary radiomics capture the mathematical relationships between pixels or voxels such as intensity histograms, mean intensity (e.g.…”
