Abstract
Objective To explore the diagnostic value of CT in the staging of silicosis.Methods Eighty silicosis patients from our hospital from January 2022 to January 2023 were selected,and all patients underwent CT examination.The diagnostic results of CT for silicosis staging and the consistency of clinical diagnostic results were compared,and the diagnostic efficacy of CT for silicosis staging was calculated.Results The CT sign analysis showed that among 80 silicosis patients,20 patients had nodules in the upper,middle,and lower regions of both lungs,36 patients had nodules in 4 lung regions,and 24 patients had nodules in 2 lung regions;39 patients had no masses,13 patients had masses ranging from 1 to 3cm,and 28 patients had masses greater than 3cm;54 patients had increased pulmonary nodule density;80 patients had different degrees of Lymphadenopathy,57 patients had lymph nodes in hilar region,23 patients had in mediastinum;60 patients had pleural thickening,involving interlobular pleura and visceral pleura.The clinical diagnosis results showed that there were 24 cases in stage Ⅰ,36 cases in stage Ⅱ,and 20 cases in stage Ⅲ among 80 silicosis patients;The CT examination results showed that there were 26 cases in Phase Ⅰ,35 cases in Phase Ⅱ,and 19 cases in Phase Ⅲ.The Kappa value was 0.884,0.823,0.898,respectively,indicating good consistency between the two.The overall accuracy of CT in staging diagnosis of silicosis was 91.25%.The accuracy of CT in staging diagnosis of stage Ⅰ,stage Ⅱ and stage Ⅲ was 95.00%,91.25%,96.25%,respectively.The sensitivity was 95.83%,88.89%,90.00%,respectively.The specificity was 94.64%,93.18%,98.33%,respectively.The positive predictive value was 88.46%,91.43%,94.74%,respectively,and the negative predictive values was 98.15%,91.11%,96.72%,respectively.Conclusion CT plays a positive role in the diagnosis of silicosis patients,can improve the diagnostic accuracy of silicosis staging,and has good diagnostic efficacy.关键词
