Then depending on the size of the available imaging studies we need to decide which pipeline to use. The contributing reasons for the latter is the fact that measured parameters on images vary depending on the vendor platform, the type of hardware and software available on the scanner, the radiographer conducting the examination, as well as the radiologist performing the imaging analysis. 2018;18(8):500–10. Tian Z, Liu L, Zhang Z, Fei B. PSNet: prostate segmentation on MRI based on a convolutional neural network. Korean J Radiol. Now that a significant number of features have been removed, we proceed with more sophisticated methods in order to further reduce the dimensionality and construct our radiomic signature that will comprise a few features.  |  He L, Huang Y, Yan L, Zheng J, Liang C, Liu Z: Radiomics-based predictive risk score: A … 1: Aerts HJ, Velazquez ER, Leijenaar RT, Parmar C, Grossmann P, Carvalho S, Bussink J, Monshouwer R, Haibe-Kains B, Rietveld D, Hoebers F, Rietbergen MM, Leemans CR, Dekker A, Quackenbush J, Gillies RJ, Lambin P.

A significant advantage of medical imaging is its ability to noninvasively visualize a cancer’s appearance, such as macroscopic tumoral heterogeneity at baseline and follow-up, for both the primary tumor and metastatic disease. Radiomics generally refers to the extraction and analysis of large amounts of advanced quantitative imaging features with high throughput from medical images obtained using computed tomography (CT), positron emission tomography (PET) or magnetic resonance imaging (MRI) (Kumar, Gu et al. 2018 Mar;286(3):800–9. In order to build more robust models, stable features should be identified. Depeursinge A, Foncubierta-Rodriguez A, Van De Ville D, Müller H. Three-dimensional solid texture analysis in biomedical imaging: review and opportunities. Radiomics converts imaging data into a multi-dimensional mineable feature space using automatically extracted data characterization algorithms . Radiologists are generating their diagnoses by visually appraising the images, drawing on past experience and applying judgment. 2015 Dec;29(10):897-905. doi: 10.1007/s12149-015-1025-z. 2012, Aerts, Velazquez et al. In k-fold cross-validation, the original sample is randomly partitioned into k equal sized subsamples (Fig. Aerts HJ et al. Gillies RJ, Balagurunathan Y. Perfusion MR imaging of breast Cancer: insights using “habitat imaging”. Either train with data from one site (or vendor) and test with data from the other sites (or vendors) or use mixed data to do both training and validation. Aerts H J W L et al 2014 Decoding tumour phenotype by noninvasive imaging using a quantitative radiomics approach Nat. In this paper, our effort was concentrated on how to avoid methodological mistakes and consider critical issues in the workflow of the development of clinically meaningful radiomic signatures. Artificial intelligence in radiology. Radiomics aims to quantify phenotypic characteristics on medical imaging through the use of automated algorithms. Unravelling tumour heterogeneity using next-generation imaging: radiomics, radiogenomics, and habitat imaging. Article  It is important to develop and follow standardized acquisition protocols that can ensure accurate, repeatable and reproducible results. eCollection 2014. 2014;18(1):176–96. Stability of radiomics features in apparent diffusion coefficient maps from a multi-Centre test-retest trial. In this way, the few highly informative, robust features constituting the “signal” of the model will be employed in constructing a robust radiomic signature [31,32,33,34]. Following the identification of stable features, we need to remove redundant features using a correlation-based feature elimination method [32]. However, deep features suffer from low interpretability, acting as black boxes and are therefore treated with variable sceptisism because they are difficult to conceptualise; compared with engineered or semantic features, which are often associated with biological underpinnings. We find that a large number of radiomic features have prognostic power in independent data sets of lung and head-and-neck cancer patients, many of which were not identified as significant before. 2019;19(1):85. 14.
