- CT-guided biopsy
- listen (… GY-ded BY-op-see)
- A biopsy procedure that uses a CT scan (a special type of x-ray linked to a computer) to find an abnormal area in the body and help guide the removal of a sample of tissue from that area. A needle is usually used to remove the sample, which is then checked under a microscope for signs of disease. A CT-guided biopsy may be done when the abnormal area is deep inside the body or when the doctor cannot feel a lump or mass.
