【摘要】Objective To investigate the value of computed tomography ( CT) texture analysis in differential diagnosis of inflammatory and malignant pulmonary nodules. Methods The image data of 54 patients with lung cancer and 36 patients with pulmonary inflammatory nodules were retrospectively collected in our hospital. All the patients received chest CT scan. CT texture analysis of entropy, correlation degree and contrast ratio were performed by the MaZda software. The receiver operating characteristic curve (ROC) was established and the area under the curve ( AUC) was calculated to evaluate the value of CT texture analysis in differential diagnosis of inflammatory and malignant pulmonary nodules. Results In the lung cancer group, the value of entropy, correlation degree and contrast ratio were 1.58± 0.07, 0.02± 0.17 and 8.79±2.59, respectively. In the inflammatory nodules group, the value of entropy, correlation degree and contrast ratio were 1.51 ± 0.04, 0.22 ± 0.16 and 12.53 ± 2.24, respectively. The differences were all statistically significant (P values were 0.008, 0.027, and 0.006, respectively) between two groups. There was not statistically significant
