Radiomics Nomogram Analyses for Differentiating Pneumonia and Acute Paraquat Lung Injury

Abstract: Paraquat poisoning has become a serious public health problem in some Asian countries because of misuse or suicide. We sought to develop and validate a radiomics nomogram incorporating radiomics signature and laboratory bio-markers, for differentiating bacterial pneumonia and acute paraquat lung injury. 180 patients with pneumonia and acute paraquat who underwent CT examinations between December 2014 and October 2017 were retrospectively evaluated for testing and validation. Clinical information including demo… Show more

“…Therefore, even if no lesions are found on the CT images, we can also analyze different types of texture features extracted to determine whether the lung tissue is damaged. In this study, through the analysis of AUTO-ML classification model, there are significant differences in the texture characteristics of non-focus area in the first CT image between the moderate and severe groups, and there are also significant differences between the moderate and severe groups and the control group, which is similar to the results of Yanling’s study of different types of pneumonia with radiomics 15 .…”

“…In previous studies, radiomics had outstanding performance in the diagnosis, staging, prognosis, and treatment response prediction of tumors [13][14][15] . In addition, radiomics can give rise to a deeper understanding of the heterogeneity of pneumonia lesions [19,25,26] . Therefore, radiomics is theoretically a feasible method to distinguish COVID-19 pneumonia from other viral pneumonia.…”
