Abstract:
Objective To explore the diagnostic value of mediastinal lymph nodes CT image features in pulmonary sarcoidosis.Methods The imageologic data of the patients with pulmonary sarcoidosis(pulmonary sarcoidosis group)and lung cancer complicating mediastinal lymph node metastasis(lung cancer group)con-firmed by EBUS-TBNA in this hospital from June 2015 to November 2023 were analyzed retrospectively.The chest plain scan CT and enhanced scan CT were performed in all cases,and the imaging characteristics were compared between the two groups.The receiver operating characteristic(ROC)curve was drawn and the area under the curve(AUC)was calculated.The diagnostic value of CT imaging characteristics in pulmonary sar-coidosis was analyzed.Results The proportion of female patients in the lung sarcoidosis group was signifi-cantly higher than that in the lung cancer group,while the age was smaller than that in the lung cancer group,and the differences were statistically significant(P＜0.05).The number of mediastinal lymph nodes,location,short diameter and CT enhancement value in the pulmonary sarcoidosis group had statistical difference(P＜0.05).The ROC curve analysis showed that AUC of lymph node short diameter reciprocal,CT enhancement value and position in detection alone were 0.586,0.785 and 0.505 respectively,and AUC of the three combined reciprocal was the highest(0.789).Conclusion The lymph node short diameter,CT enhancement value and po-sition have certain value in clinical diagnosis of pulmonary sarcoidosis and the 3-indicator combination could increase the diagnostic efficiency of pulmonary sarcoidosis.
