The rise of lung cancer screening programs and advances in medical imaging have dramatically changed the spectrum of lung lesions presented for CT-guided biopsy. Radiologists are increasingly faced with more technically challenging lesions where traditional fine-needle aspiration techniques are not always applicable. This exhibit will present: What constitutes a difficult lung lesion Different and innovative lung biopsy techniques Pitfalls and complications to be aware of  

1) Schematic approach to defining a difficult lung biopsy Patient factors (i.e. respiratory motion) Lesion location Small size Adjacent structures 2) Biopsy techniques to improve success (using cases from our institution which oversees a large lung cancer screening program) Atypical patient positioning Atypical biopsy needle (i.e. curved needles, bevel-steering) Hydrodissection Induced pneumothorax 3) Complications Pneumothorax Pulmonary hemorrhage
