Google Scholar. Request PDF | Radiomics and deep learning in lung cancer | Lung malignancies have been extensively characterized through radiomics and deep learning. Recurrent Residual Convolutional Neural Network Based on U-Net. Don't use plagiarized sources. The ongoing development of new technology needs to be validated in clinical trials and incorporated into the clinical workflow. In the dataset, the diameters of 189 (50.7%) GGNs were smaller than 10 mm, the diameters of 148 (39.7%) GGNs were in a range of (10 mm, 20 mm), and the diameters of 36 (9.6%) GGNs were larger than 20 mm (P < 0.05). doi: 10.1016/j.athoracsur.2018.06.058, 8. Moreover, this is an only technique development study, and we need to conduct rigorous and valid clinical evaluation before applying the proposed scheme into clinical practice. We report initial production of a combined deep learning and radiomics … Radiology. ACM Comput Surv. Due to the different scanning parameters, the tube current, pixel spacing, and slice thickness of CT image was variety. As an analytic pipeline for quantitative imaging feature extraction and analysis, radiomics has grown rapidly in the past decade. This research was supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF), which is funded by the Ministry of Science, ICT and Future Planning (NRF- 2017R1A2B4003114). Figure 2 shows an example of GGN segmentation results. So we expect that deep learning is able … Technologies such as radiomics allow to extract significantly more information from scans than what human visual assessment is capable of. The proposed RDL has achieved an overall accuracy of 0.913, which significantly outperforms the other methods (p <  0.01, analysis of variation, ANOVA). The radiomics feature analysis approach mainly includes tumor segmentation, radiomics feature extraction and selection (8), and machine-learning classifier training/testing process, respectively (9–11). 10:418. doi: 10.3389/fonc.2020.00418. Review of the use of Deep Learning and Radiomics in Ovarian Cancer Detection. The diversity of GGNs in our dataset cannot sufficiently represent the general GGN population in clinical practice. Software-based risk stratification of pulmonary adenocarcinomas manifesting as pure ground glass nodules on computed tomography. Thus, how to improve the CADx performance with a limited dataset is a challenge task. Since DL based scheme and radiomics feature based scheme used different imaging features to decode the phenotypes of GGN, our fusion model integrated these quantitative and deep features to character the CT features of tumor. doi: 10.1007/s00330-018-5530-z, 7. Quantitative CT analysis of pulmonary ground-glass opacity nodules for distinguishing invasive adenocarcinoma from non-invasive or minimally invasive adenocarcinoma: the added value of using iodine mapping. Figure 3 shows the architectures of our proposed DL model. All authors reviewed the manuscript. About the relationship between ROC curves and Cohen's kappa. For stage-I lung adenocarcinoma, the 5-years disease-free survival (DFS) rates of non-invasive adenocarcinoma (non-IA) is different with invasive adenocarcinoma (IA). Meanwhile, comparing with previously reported studies (15, 19, 28), our study can yield a rather high classification performance by using a limited dataset (i.e., results showed in Table 4). For maximum and minimum strategy, we compared two prediction scores of each GGN, and selected the maximum or minimum value as the fusion prediction score. In training and validation dataset, the mean CT value of IA and non-IA GGNs were −439 ± 138 and −533 ± 116, respectively. In deep learning using the per‐slice basis, the area under the receiver operating characteristic (ROC) was comparable for tumor alone, smallest and 1.2 times box (AUC = 0.97‐0.99), which were significantly higher than 1.5 and 2.0 times box (AUC = 0.86 and 0.71, respectively). Keywords: breast cancer, deep learning, radiomics, axillary lymph node metastasis, breast ultrasound, peritumoral region. Our study has a number of characteristics. the paper should include a table of comparison which will review all the methods and some original diagrams. It demonstrated that CT image based AI scheme was an effective tool to distinguish between non-IA and IA GGNs. The results showed that our RDL framework with an accuracy of 0.966 significantly surpassed other methods. According to the guideline of the 2011 International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society International (IASLC/ATS/ERS) classification, lung adenocarcinoma includes atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), and minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma (IA) (2). In order to train and test our proposed schemes, we divided the GGNs into two parts. In future studies, we should also apply and combine other types of features (i.e., clinical information, tumor biomarkers, gene feature) to improve the scheme performance (30). J Digit Imaging, 26 (6) (2013), pp. (2014) 273:285–93. Thus, we should investigate and develop new fusion methods to fuse the different types of features in future studies. At present, radiomics and deep learning are still in development, and challenges still exist – e.g., how to automatically extract features with clinical meanings, how to train a deep network with a small number of data samples, how to fuse multi-source information, and how to design representation learning with high interpretability. Share. 13411950107, the Zhejiang Provincial Science and Technology Project of Traditional Chinese Medicine under Grant No. Many powerful open‐source and commercial platforms are currently available to embark in new research areas of radiomics. The comparison of classification performance tested on 127 GGNs in independent testing dataset, in terms of accuracy (ACC), F1 score, weighted average F1 score, and Matthews correlation coefficient (MCC), respectively. First, our dataset was small, and only a total of 373 GGNs were involved in this study. Classification and mutation prediction from non–small cell lung cancer histopathology images using deep learning. 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).

Pritzker Professor of Radiology / Medical Physics The University of Chicago m-giger@uchicago.edu Giger AAPM Radiomics 2020. (2017) 209:1216–27. Meanwhile, the standard surgical treatment for lung adenocarcinoma is still lobectomy, but non-IA patients may be candidates for limited surgical resection (6). When we applied the information-fusion method, the scheme performance changed with the different fusion strategy. Then, we used an intensity window range of [−1,200, 600] to scale the resampled axial CT images to an intensity range of 0–255. By using a maximum fusion strategy, our scheme yielded a highest AUC value of 0.90 ± 0.03. Read More. doi: 10.1007/s00330-019-06533-w, 29. In this present work, we investigate the value of deep learning radiomics analysis for differentiating T3 and T4a stage gastric cancers. (2019) 64:135015. doi: 10.1088/1361-6560/ab2757, 10. The architectures of Recurrent Residual Convolutional Neural Network (RRCNN) based on U-Net model and the transfer learning method based risk prediction model. Third, to improve the classification performance, we fuse the prediction scores of two schemes by applying an information fusion method. In order to compare the new scheme performance with radiologists, we conducted an observer study by testing on an independent testing dataset. Clin Cancer Res, 25 (2019), pp. Second, we only extracted and investigated two type CT image features of lung adenocarcinoma namely, DL image feature and radiomics feature, respectively. Table 3 summarizes the multivariate … (2018) 45:5472–81. Zhao W, Yang J, Sun Y, Li C, Wu W, Jin L, et al. The insufficient diagnosis time and clinical information may result in the low performance of two radiologists.
