CT Core Biopsy

A CT-guided core biopsy (CNB) is a minimally invasive procedure that uses a CT scan to help guide a needle in removing a tissue sample from the body. The CT scan, or computed tomography scan, uses an X-ray machine to take detailed images of the body's organs and tissues. 

When is this procedure recommended?

CT Core Biopsy may be requested when an abnormal area is deep inside the body or when they are unable to feel a lump or mass.  The procedure is performed to diagnose lung, pleural, or mediastinal lesions. 

How is the procedure performed?

During the procedure, our interventional radiologist utilizes CT technology to guide a needle into the lesion to obtain a tissue sample, in the safest way possible. The tissue sample is then sent to a laboratory to be examined and analyzed  for signs of disease

What are the benefits?

  • Less invasive than open surgical biopsies with fewer complications and faster recovery time
  • No general anesthesia required
  • Use of imaging guidance allows for visualization of anatomical details, allowing access to almost any point in the body with more accuracy
  • Provide effective, non-invasive diagnosis of tumors
