Introduction The Standardized Environment for Radiomics Analysis (SERA) Package is a Matlab®-based framework developed at Johns Hopkins University that calculates radiomic features based on guidelines from the Image Biomarker Standardization Initiative (IBSI). These radiomics features have the potential to unravel disease characteristics that could be missed by the naked eye. The process of creating a database of correlative quantitative features, which can be used to analyze subsequent (unknown) cases includes the following steps 3. Radiomics has emerged … Here are some Here are some words which will help you to describe a diagram. SERA is capable of processing images from various clinical imaging modalities such as CT, MRI, PET and SPECT. For large data sets, an automated process is needed because manual techniques are usually very time-consuming and tend to be less accurate, less reproducible and less consistent compared with automated artificial intelligence techniques. 41-43 This noninvasive process allows for the ability to describe tumor characteristics while accounting for spatial and temporal heterogeneity. Radiomics feature has been applied as the noninvasive alternative to identify the genomic and proteomic changes in tumors, which also broadly utilized in tumor diagnosis, prognosis prediction, treatment selection, gene prediction, and so on [ 15 – 18 Radiomics is a complex multi-step process aiding clinical decision-making and outcome prediction Manual, automatic, and semi-automatic segmentation is challenging because of reproducibility issues Quantitative features are mathematically extracted by software, with different complexity levels By continuing you agree to the use of cookies. Radiomics is the comprehensive analysis of massive numbers of medical images in order to extract a large number of phenotypic features (radiomic biomarkers) reflecting cancer traits, and it explores the associations between the features and patients’ prognoses in order to improve decision-making in precision medicine. Bases: radiomics.base.RadiomicsFeaturesBase First-order statistics describe the distribution of voxel intensities within the image region defined by the mask through commonly used and basic metrics. Introduction The Standardized Environment for Radiomics Analysis (SERA) Package is a Matlab®-based framework developed at Johns Hopkins University that calculates radiomic features based on guidelines from the Image Biomarker Standardization Initiative (IBSI). Radiomics analysis of molecular imaging is expected to provide more comprehensive description of tissues than that of currently used parameters. The hypothesis of radiomics is that the distinctive imaging features between disease forms may be useful for predicting prognosis and therapeutic response for various conditions, thus providing valuable informati… He, J. Ma, Wu, Xie, Song, Yao. The central hypothesis of radiomics is that distinctive imaging algorithms quantify the state of diseases, and thereby provide valuable information for personalized medicine. Radiomics is an emerging translational field of research aiming to extract mineable high-dimensional data from clinical images. YK, SSA, and S-KL designed the radiomics pipeline and performed the radiomics analyses. As improvements continue in bioinformatics, image analysis, statistical/machine learning models, and end-user experience with data interpretation, integration into the clinical workflow of a radiation oncologist is bound to occur soon. 2, Table 1) . Statistical Analysis The continuous variables were ... Chen L, et al. A multiple logistic regression analysis was applied to develop the clinical factors model by using the significant variables from the univariate analysis as inputs. Paired t-tests were performed on the features and Wilcoxon signed-rank tests were carried out on the features that violated the normality assumption. 2012, Lambin, Rios-Velazquez et al. Conclusions: The radiomics nomogram based on CT images showed favorable prediction performance in the prognosis of COVID-19. To investigate whether machine learning-based analysis of MR radiomics can help improve the performance PI-RADS v2 in clinically relevant prostate cancer (PCa). All statistical analyses were performed by R software (version 3.6.1). The radiomic process can be divided into distinct steps with definable inputs and outputs, such as image acquisition and reconstruction, image segmentation, features extraction and qualification, analysis, and model building. Using a variety of reconstruction algorithms such as contrast, edge enhancement, etc. Correction for multiple comparisons was performed by using Benjamini-Hochberg method. The field of radiomics, in particular, requires a renewed focus on optimal study design/reporting practices and standardization of image acquisition, feature calculation, and rigorous statistical analysis for the field to move forward. SERA is capable of processing images from various clinical imaging modalities such as CT, MRI, PET and SPECT. For both scripts, an additional parameter file can be used to customize the extraction, and results can be directly imported into many statistical packages for analysis, including R and SPSS. Quantitative imaging research, however, is complex and key statistical principles should be followed to realize its full potential. The Student’s t test and the Chi-square test were used to compare the general characteristics of the patients in the two groups. 2. Moreover, radiomics has recently been recognized as a newly emerging form of imaging technology in oncology using a series of statistical analysis tools or data-mining algorithms on high-throughput imaging features to obtain predictive or prognostic information .
