CT-Guided Biopsy

When a scan shows a nodule, mass or area of concern in the lung, a CT-guided biopsy lets us take a small tissue sample from exactly the right spot. Real-time CT images guide a fine needle through the chest wall to the target, giving the laboratory a sample to work with — often avoiding the need for surgery just to reach a diagnosis.

When it is recommended

A lung nodule or mass that needs a tissue diagnosis
An unexplained shadow or mass on a CT scan
Suspected lung cancer or infection
Lesions near the chest wall that are hard to reach by bronchoscopy

What it involves

Under local anaesthesia and CT guidance, a thin needle is advanced to the target, its position confirmed on the scan, and a sample taken. The procedure usually takes 30–45 minutes.

What to expect

You are monitored afterwards and have a chest X-ray to check for any small air leak. Most people go home the same day; mild discomfort or a little blood-streaked phlegm can occur and settles quickly.
