A needle biopsy of the lung uses imaging guidance to help locate a nodule
or abnormality and remove a tissue sample for examination under a microscope.
A biopsy may be necessary when imaging tests cannot confirm that a nodule
is benign, or a nodule cannot be reached by bronchoscopy or other methods.
Needle biopsy is less invasive than surgical biopsy and may not require

on the skin.
- The skin around the insertion site will be scrubbed and disinfected, and
a clean and sterile drape will be applied.

- A very small nick is made in the skin at the site where the biopsy needle
is to be inserted.
- Using imaging guidance, the physician will insert the needle through the
skin, advance it to the site of the nodule and remove samples of tissue.
Several specimens may be needed for complete analysis.
- After the sampling, the needle will be removed.
