A lung needle biopsy is a method to remove a piece of lung tissue for examination. If it is done through the wall of your chest, it is called a transthoracic lung biopsy.
Transthoracic needle aspiration; Percutaneous needle aspiration
How the Test is Performed
The procedure usually takes 30 to 60 minutes. The biopsy is done in the following way:
- A chest x-ray or chest CT scan may be used to find the exact spot for the biopsy. If the biopsy is done using a CT scan, you may be lying down during the exam.
- You may be given a mild sedative to relax you.
- A needle biopsy of the lung may also be done during bronchoscopy or mediastinoscopy.
- You sit with your arms resting forward on a table. Your skin where the biopsy needle is inserted is scrubbed.
- A local painkilling medicine (anesthetic) is injected.
- The doctor makes a small cut in your skin.
- The biopsy needle is inserted into the abnormal tissue, tumor, or lung tissue. A small piece of tissue is removed with the needle.
- The needle is removed. Pressure is placed on the site. Once bleeding has stopped, a bandage is applied.
- A chest x-ray is taken right after the biopsy.
- The biopsy sample is sent to the lab. Analysis usually takes a few days.
