Conclusion
In this series of 113 consecutive PTLNB performed for lung nodule evaluation in the general chest interventional radiology setting, the overall nondiagnostic rate was 19.5%, increasing to 26.8% for nodule size <= 20 mm.
For confirmed final diagnosis of a malignant nodule, PTLNB false negative rate was 5/85 (5.9%).
Further 13/85 (15.3 %) of procedures were limited by insufficient material for optimal oncological management.
PTLNB limitation was not adversely impacted by small size - combined false negative and insufficient characterisation rate was 5/30 (16.7%) for nodules <=20 mm.
Subsolid nodules <=20 mm were more likely to show inadequate results.
