Abstract：Objective:To analyze the diagnostic value of thin slice CT mapping navigation combined with rapid field assessment(ROSE)in pulmonary peripheral lesions(PPLs).Methods:A total of 80 patients with suspected PPLs ad-mitted to hospital from February 2022 to February 2024 were randomly divided into control group and observation group,with 40 cases in each group.The control group was treated with thin-layer CT navigation for routine bronchos-copy biopsy,and the observation group was treated with thin-layer CT navigation combined with ROSE technique for biopsy.According to the results of routine cell and histological examination after operation as the gold standard,the complications,diagnostic positive rate,puncture times and puncture time were compared between the two groups.The diagnostic efficacy of thin-slice CT+ROSE in peripheral pulmonary lesions was calculated according to the ROC curve.Results:The incidence of complications in the observation group was higher than that in the control group,but there was no significant difference between the two groups(P＞0.05).The number of punctures in the observation group was lower than that in the control group(P＜0.05),the puncture time was higher than that of the control group(P＞0.05).The total positive rate of the observation group was higher than that of the control group,but there was no significant difference between the two groups(P＞0.05).According to the results of ROC curve analysis,the AUC of conventional bronchoscopy biopsy and thin-layer CT navigation combined with ROSE biopsy for early prediction of PPLs were 0.793 and 0.872,respectively.Conclusion:Thin-slice CT navigation combined with ROSE biopsy has a good diagnostic positive rate for PPLs,which can improve specimen quality,shorten detection time and has good safety.
