Deep learning frameworks in particular have achieved high sensitivity and specificity in classifying MR images of gliomas by IDH1, 1p19q codeletion, and MGMT promoter methylation status. 19. Imaging parameters of high grade gliomas in relation to the MGMT promoter methylation status: the CT, diffusion tensor imaging, and perfusion MR imaging. In the image of the tumor with a low expression of S100 (Figure 4B), the tumor mass effect was obvious, but there was no obvious enhancement, and the surrounding edema was not obvious, which was diagnosed as astrocytoma (WHO II grade). Principal Component Analysis (PCA) was applied for high-dimension reduction that maps n-dimensional features to k-dimensional features (n > k), resulting in brand new orthogonal features.

Among these patients, 40 patients were under 18 years old, seven patients had quality issues on their MRI data, and four patients did not have an assigned WHO classification level in their records. The RF models performed slightly better, when compared to the other models. The commonly and frequently used ML algorithms in radiomics include Logistic Regression (LR), Random Forests (RF), Support Vector Machine (SVM), and etc. After grid search with cross validation (cv = 5) or K fold validation (n_splits = 5), the selected classifier included: (1) LR (penalty = “l2,” C = 1.0), (2) SVM (C = 1, kernel = “rbf,” and gamma = “auto”), and (3) RF (min_samples_leaf = 1,min_samples_split = 2, and n_estimators = 100).

The machine-learning based radiomics approach was applied to predict glioma grades and the expression levels of pathologic biomarkers Ki67, GFAP, and S100 in low or high. As it is known, the roles of these biomarkers can be complicated and controversial in laboratory experiments (26). Machine learning–based radiomics provides the potential for noninvasive and efficient assessment of 2016 WHO classification of glioma subtypes. All significant levels were tested at 0.05. Figure 3 shows the AUC_ROC for the RF classifier in sub test sets. With the emergence of Artificial Intelligence (AI) technologies, advanced informatics tools have become accessible to facilitate machine learning (ML) based radiomics applications using image features as the data source (10). One important finding in our study was that our RML model yielded a performance that was comparable to but not better than the monoparameter mean ADC. Methods: The present study retrospectively collected a dataset of 367 glioma patients, who had pathological reports and underwent MRI scans between October 2013 and March 2019.

Radiomics can generate image features with high dimensional data from the intensity histogram, geometry and texture analyses on the entire tumor volume (9). 4 Radiomics Certificate Course –2018 AAPM Annual Meeting. So far, it is not surprising to know that most radiomics studies favor the prediction of the IDH expression for molecular diagnosis (11, 27), with a few reports on Ki67 (28). Before we can reach this goal, they must be thoroughly assessed in prospective, multicentric trials to prove their … Kristensen BW, Priesterbach-Ackley LP, Petersen JK, Wesseling P. Molecular pathology of tumors of the central nervous system. MRI radiomics based on machine learning. This result may echo that GFAP is not a direct predictor of low grade gliomas (15, 26). 6 Thus, these radiomic features can serve ML applications. https://doi.org/10.1007/978-3-030-27359-0_15. Radiomics is gaining ground in oncology and have the potential to accurately classify or predict tumor characteristics. The RF model built-in feature importance is presented in Figure 2. Oncol Lett. Wiestler B, et al. On training set, the grid search with cross-validation was applied for hyper parameters tuning (RF and SVM), and k fold validation was used for LR.

Results: Machine Learning has several promising applications in treatment planning with automatic organ at risk delineation improvements and adaptative radiotherapy workflow automation. The class distribution was 323:15. Moreover, there were significant differences in glioma grade, tumor size, age and gender for the Ki67 expression. Two postdoctoral training positions are available in the laboratory of Ivan Pedrosa, M.D., Ph.D., in the Department of Radiology at UT Southwestern Medical Center to study Radiogenomics and Machine Learning Approaches to Develop Predictive and Prognostic Biomarkers in Kidney Cancer. This study demonstrated that multiple pathologic biomarkers in gliomas can be estimated to the certainty levels of clinical using common ML models on conventional MRI data and pathological records. Fourth, after PCA reducing feature dimensions, a new set of features was less remained but difficult to interpret. Radiomics, or texture analysis, is a rapidly growing field that extracts quantitative data from imaging scans to investigate spatial and temporal characteristics of tumors . J Biol Chem. Figure 4. The scores ranged within 3.67–44.04. For example, few patients received an IDH1 test before 2017, but after 2016, the WHO classification standard was published, and IDH1 tests became common. Multimodal MRI features predict isocitrate dehydrogenase genotype in high-grade gliomas.

Clin Neurol Neurosurg. NeuroImage. It leads to the discovery of new marker patterns and disease signatures in imaging and clinical record data, and the linking of these signatures to disease course and prediction of treatment response. The RF classifier on glioma grades achieved a predictive performance (AUC: 0.79, accuracy: 0.81). In order to reduce the influence of different scanning parameters, post-processing and image registration were applied using the Advanced Normalization Tools (ANTS 2.1, PA). Kickingereder et al.

Objectives To develop and test machine learning-based CT radiomics models for predicting hospital stay in patients with pneumonia associated with SARS-CoV-2 infection. Sequential MRI radiomics feature selection was performed using (i) MRMR and (ii) a generalized linear regression model using elastic net constraints. For the high expression of S100 case (Figure 4A), the tumor exhibited an obvious rosette enhancement, no enhancement of internal necrotic components, and a few edema zones around it, and was diagnosed as glioblastoma (WHO IV grade). Comparing the overall results from three biomarker prediction models, the combination of PCA reduction and RF classification consistently performed best. Those patients who are not eligible for a surgery or seek non-surgical treatment may have limited treatment options without pathological guidance. The AUC and accuracy score for S100 expression levels are 0.60 and 0.91. 104.238.92.55. Micros Res Tech. Moon WJ, et al. Ki67, S100, or GFAP may not be a reliable diagnostic biomarker for gliomas, because their roles in gliomas are still under investigations, while controversies have been observed in experiments (26). of optimal machine-learning methods for radiomics-based prognostic analyses could broaden the scope of radiomics in precision oncology and cancer care.
