ABSTRACT

Objective To analyze the CT characteristic of pulmonary inflammatory mass and peripheral lung cancer, and to look for the method of diagnosis solitary pulmonary nodule. Methods 28 patients of pulmonary inflammatory masses and 33 patients of peripheral lung cancers were included in the study,all patients conformed by pathology. The lesions were divided into typical and atypical masses according to morphology. Observing the signs of lesions and using the results ameliorate the morphological classification. Tested the method by ROC. Results According to the standard of morphology, the diagnosis sensitivity, specificity and accuracy of inflammatory mass are 64.3%, 72.7% and 68.9% respectively. The ameliorated sensitivity, specificity and accuracy are 75%, 81.8% and 78 7% respectively. Conclusion The method of making morphology as basement and sign as supplement can improve the sensitivity, specificity and accuracy of diagnosis.
