[Abstract] Objective To study the application of electromagnetic navigation technology (ENB) combined with radial ultrasound (r-EBUS) in the diagnosis and treatment of small peripheral pulmonary lesions(average lesion size was 18.95mm and mean distance between pleura and lesion was 1.27cm). Methods ENB was performed by fiberoptic bronchoscopy; the location of the lesion was determined by radial ultrasound after navigation, and biopsy specimens were obtained through the working channel. Results A total of 33 lesions in 32 cases,the navigation success rate was success rate was 87.87%(29/33).The sensitivity,specificity,agreement rate,negative predict value and Youden index were 50%(6/12),100%(21/21),81.82%(27/33),77.7%(21/27) and 0.5,respectively.The consistency of ENB combined with r-EBUS and gold standard was moderate(Kappa=0.56).Conclusion For small peripheral pulmonary lesions,ENB can be promoted as a new effective bronchoscopy technique in combination with radial ultrasound.
