CT-guided biopsy

During a CT-guided biopsy, our doctors insert a biopsy needle into the body under the guidance of images generated by a CT scanner. A computed tomography (CT) scan (also known as a computed axial tomography scan, or CAT scan) uses X-ray technology to produce detailed images of areas inside the body to assist our doctors in accurately placing a needle into tissue to remove a sample for testing.

During the scan, patients lay down inside a CT machine, which takes images from many angles as the X-ray tube revolves around the patient’s body. After the biopsy is complete, a pathologist inspects the cells under a microscope, looking for cancerous abnormalities.
