Objective:
To develop a set of combined criteria of multiple features of chest CT for discriminating between benign and malignant lung lesions.
Methods:
Patients whose chest CT showed abnormalities were recruited from the West China Hospital in March and April 2010. The patients were examined with bronchoscopy and the results of CT and pathology were compared.
Results:
A total of 105 patients participated in this study and 85 had confirmed pathological results. The CT identified 27 cases of malignant lesions, 22 of which were confirmed by the pathology. The CT identified 58 cases of benign lesions, 55 of which were confirmed by the pathology. The set of combined criteria of multiple features of chest CT had an accuracy of 90.59%, a sensitivity of 88.00%, and a specificity of 91.67% in diagnosing benign and malignant lung lesions.
Conclusion:
The combined criteria of multiple imaging signs of CT have good clinical values for diagnosing malignant lung lesions.
