Resident Experience Associated with Lung Biopsy Outcomes: A Cross-Sectional Study of Diagnostic Radiology Residents. Does the Level of Training Matter?

6 A previous study analyzing diagnostic accuracy similarly did not find significant risk factors for a nondiagnostic sample when using a core needle, though the depth of the lesion from the pleural surface approached significance. 22 Another showed that nondiagnostic biopsies were most likely to occur when there was a moderate or high pretest probability of infection, as opposed to malignancy, though this study was performed with fine needle aspirations as opposed to core needle biopsies. 23 Only a handful of studies analyzing risk factors for nondiagnostic and complication rates of core needle lung biopsies have recorded operator experience as a variable, making our study unique.
