A CT-Guided Lung Biopsy is a focused procedure to sample an abnormal spot or nodule found inside your lungs.
Common Indications for Lung Biopsy
Your doctor may request this procedure if you have:
- A suspicious lump, mass, or nodule found on a recent chest X-ray or CT scan.
- A persistent lung infection that isn't responding to standard treatments.
What happens during the procedure?
You will lie on the scanner table. The doctor will run a short CT scan to map out exactly where the lung nodule is. After numbing the skin on your chest or back, the doctor will slowly insert a thin needle between your ribs, checking the CT images constantly to make sure the needle is moving safely past the blood vessels and straight into the nodule.
Do I need to prepare?
You will typically be asked to fast for a few hours. You must also let your doctor know if you take any blood thinners, as these will need to be stopped.
How long does it take?
The procedure takes about 30 to 45 minutes. You will be monitored in a recovery room for about 4 hours afterward.
Will it be painful?
The skin and chest wall will be fully numbed. You may feel a pushing sensation as the needle goes in. The most common side effect is coughing up a very small amount of blood afterward, which is normal and clears up quickly. There is also a small risk of a pneumothorax — when some air leaks out of the lung into the chest cavity — and your doctor will do a quick chest X-ray before you leave to make sure your lung is safe.
Conclusion
A CT-Guided Lung Biopsy avoids the need for major chest surgery to diagnose a lung spot. The CT scanner acts as an accurate GPS, making the process safe, fast, and remarkably precise.
