The authors used a gantry tilt of 20-degrees in five patients to allow
fine-needle aspiration biopsy of peripheral pulmonary lesions that we
re difficult to approach with a vertical alignment because of overlyin
g ribs. This method allowed a direct approach to the lesion in all fiv
e cases, with the entire needle path visible in the scanning plane, av
oidance of vital structures, and traversal of a minimal amount of norm
al lung parenchyma.
