“…Therefore, the consensus on the degree of radiomics reliability that has been achieved, or could be achievable in radiomics research could not be safely derived. Fourth, radiomics feature reliability has been suggested to be dependent on imaging modality, organ, disease, and other factors, which was also noticed in some included individual studies (72,89,91,103,104,158). But these dependencies could not be further generalized in this review.…”

“…Moreover, (semi-)automatic segmentation was frequently reported useful to further reduce the intra-/inter-observer radiomics feature variability induced by manual segmentation in the included studies in addition to its advantage in segmentation time, suggesting the future role of (semi-)automated segmentation in more reliable and cost-effective/efficient radiomics analysis (67,69,70,77,80,99,103,141,142). (18,36,44,57,134), post-processing and quantification (36,115,116,128,130,132), and segmentation (94,99,104,(142)(143)(144)(145). In different types of texture features, GLCM (gray-level co-occurrence matrix) features were observed to be more robust than other texture features in a few studies (18,44,94,116,128,143,145…”

“…The wavelet transform can decompose the image into low-frequency elements and/or high-frequency components at different scales, and the texture features obtained from the wavelet decomposition of the original data can signify different frequency ranges within the tumor volume [ 31 ]. Some studies have demonstrated that wavelet-based features are important in radiomics studies and can show promising capabilities in terms of tumor classification and prognosis [ 32 , 33 ]. Our study also indicates the value of wavelet features in predicting MKI status.…”

“…To reduce the variation in different scanners, a two-step method of the image preprocessing was conducted before radiomics features extraction. Firstly, due to different pixel sizes and slice thicknesses of various CE-CT scanners, all the CT slices were resampled to 1 × 1 × 1 mm 3 using the bicubic interpolation [ 30 ]. Secondly, the images were normalized to 64 grey levels to compensate for the variation of CE-CT scanners.…”
