Clinical and radiomic factors for predicting invasiveness in pulmonary ground‑glass opacity

Abstract: Patients with preinvasive or invasive pulmonary ground-glass opacity (GGO) often face different clinical treatments and prognoses. The present study aimed to identify the invasiveness of pulmonary GGO by analysing clinical and radiomic features. Patients with pulmonary GGOs who were treated between January 2014 and February 2019 were included. Clinical features were collected, while radiomic features were extracted from computed tomography records using the three-dimensional Slicer software. Predictors of GGO … Show more

“…Most current studies on the radiomics of lung nodules use supervised learning algorithms, [23] which give the computer different nodule pathological results or prognosis information and establish predictive models after a large amount of simulation calculation. [24] Although this method can achieve high predictive accuracy, it may face the risk of over tting and have poor generalization. [25,26] This study used an unsupervised learning method, letting the computer group based on the similarity of nodule radiomics data and then interpret the classi cation results based on the classi cation results.…”
