Diagnostic accuracy and complications of CT-guided core needle lung biopsy of solid and part-solid lesions

Objective:To evaluate whether diagnostic accuracy and complications of CT-guided core needle biopsy (CNB) differ for solid and part-solid lung lesionsMethods:This retrospective study included 354 consecutive patients from April 2012 to July 2016 who underwent CT-guided CNB of lung lesions by a radiologist. Patient demographics, lung lesions’ characteristics; solid or part-solid, underlying pulmonary disease, distance of path, procedure time, complications (hemorrhage or pneumothorax), histopathological results of biopsy specimens and final diagnosis were reviewed. The diagnostic yields, biopsy-related factors and complications were compared for patients with solid lesions and patients with part-solid lesions. Factors related to true diagnoses and complications were analyzed statistically.Results:The biopsies of part-solid lesions take more time (p = 0.021). Non-diagnostic biopsies were not statistically different between solid and part-solid lesions (p = 0.804). There was no significant difference in the ...
