In this talk I will discuss the development work in CCIPD on new radiomic and pathomic and deep learning approaches for capturing intra-tumoral heterogeneity and modeling tumor appearance.

Nat Med. doi: 10.1158/0008-5472.CAN-17-0339, 27. ... To extract radiomics first-order distribution and texture features … We used 246 GGNs in the first dataset to build a training and validation dataset to train our scheme. To reduce the dimensionality of initial features, we applied the univariate feature selection method with ANOVA F-value to select the best features and remove the redundant features (24). Performance comparisons of three models and radiologists. 2020 Apr;21(4):387-401 Authors: Park HJ, Park B, Lee SS Abstract Radiomics and deep learning have recently gained attention in the imaging assessment of various liver diseases. The pixel spacing of CT scan ranged from 0.684 to 0.703 mm, and the slice thickness was 1.25 or 5 mm. Sci Rep, 7 (1) (2017), p. 10353. deep learning/radiomics approach is more accurate than using only one feature type, or image mode. Learning methods for radiomics in cancer diagnosis. The diversity of GGNs in our dataset cannot sufficiently represent the general GGN population in clinical practice. Deep Learning vs. Radiomics for Predicting Axillary Lymph Node Metastasis of Breast Cancer Using Ultrasound Images: Don't Forget the Peritumoral Region Qiuchang Sun 1 † , Xiaona Lin 2 † , Yuanshen … It can be seen that LoG features play an important role in building the radiomics feature based classification model. RDL framework reached accuracy of 0.966 in the verifying of an independent dataset. High-grade lung ADC based on histologic pattern spectrum in GGO lesions might be predicted by the framework combining radiomics with deep learning, which reveals advantage over radiomics alone. (2016) 30:266–74. (R2U-Net) for Medical Image Segmentation. doi: 10.1038/s41591-018-0177-5, 18. Heat map of the 20 imaging features selected in the radiomics based model. Radiomics involves the extraction of high-dimensional quantitative data reflecting imaging phenotypes. In this study, we investigate and develop CT image based artificial intelligence (AI) schemes to predict the invasiveness risk of lung adenocarcinomas, and incorporate deep learning (DL) and radiomics features to improve the prediction performance. (B) Shows boxplot of the testing dataset. In order to evaluate the performance of our new scheme, we used an independent dataset to conduct an observer study by comparing our prediction score with two radiologists (an experienced senior radiologist S.P. The citation should include all the papers from … Comparing with the performance generated individually, the fusion scheme significantly improved the scheme performance (P < 0.05). In this present work, we investigate the value of deep learning radiomics analysis for differentiating T3 and T4a stage gastric cancers. Lung malignancies have been extensively characterized through radiomics and deep learning. For stage-I lung adenocarcinoma, the 5-years DFS of AIS and MIA is 100%, but IA is only 38–86% (4, 5). Wang and a junior radiologist W. Hao). In this study, we respectively collected 373 surgical pathological confirmed GGNs from two centers. Deep learning models that incorporate radiomics features promise to extract information from brain MR imaging that correlates with response and prognosis. Fourth, we built a radiomics feature analysis model to classify between non-IA and IA GGNs. Each slice was reconstructed with an image matrix of 512 × 512 pixels. We hypothesized that deep learning could potentially add valuable information to diagnosis by capturing more features beyond a visual interpretation. Two radiologists (a junior radiologist: Wen Hao with 5-years experience; a senior radiologist: Shengping Wang with 14-years experience in CT interpretation) were independently to diagnose all the GGNs in testing dataset by blinding to the histopathologic results and clinical data. Central focused convolutional neural networks: developing a data-driven model for lung nodule segmentation. It indicated that these selected imaging features had a potential to classify between non-IA and IA GGNs. doi: 10.1016/j.athoracsur.2018.06.058, 8. Comparing with two radiologists, our new scheme yielded higher performance in classifying between non-IA and IA GGNs (i.e., results showed in Figure 6 and Table 3). Figure 6A shows scatter plot of prediction score distributions of non-IA and IA nodules, and Figure 6B shows ROC curves of the three models and the prediction scores of two radiologists. Fan L, Fang MJ, Bin LZ, Tu WT, Wang SP, Chen WF, et al. In training and validation dataset, the mean CT value of IA and non-IA GGNs were −439 ± 138 and −533 ± 116, respectively. © 2020 Elsevier B.V. All rights reserved. Ann Thorac Surg. The results showed that our RDL framework with an accuracy of 0.966 significantly surpassed other methods. It demonstrates that applying AI method is an effective way to improve the invasiveness risk prediction performance of GGNs. The results shows that fusion of DL and radiomics features can significantly improve the scheme performance.
