The Value of Texture Analysis Based on Chest Three-Phase CT Images in Distinguishing Benign and Malignant Pulmonary Nodules
Objective:To analyze the value of texture analysis of third-stage CT images of chest in the identification of benign and malignant nodules in the lungs.Methods:A total of 109 patients with pulmonary nodule lesions who visited our hospital from January 2018 to December 2021 were selected as the observation subjects.All patients were confirmed by pathology and had a total of 120 nodules.Plain scans were performed on all patients and texture analysis of chest three-phase CT images was performed.Results:Among the 120 nodules,pathological confirmation showed 69 benign nodules and 51 malignant nodules.The sensitivity,specificity,and accuracy of plain scan results were 47.06%,97.10%,and 75.83%,respectively.However,the sensitivity,specificity,and accuracy of chest three-phase CT images were 49.02%,95.65%,and 75.83%,respectively.There was no statistically significant difference between the groups.Conclusion:Through the texture analysis of a series of pulmonary nodule images,the texture characteristic parameter set of nodules can be obtained,which can provide scientific data for clinical practice combined with clinical diagnosis results,but has no special value in distinguishing benign and malignant nodules.
