A computed tomography (CT) scan uses a special X-ray machine to take detailed pictures of the body’s organs and tissues.
In a biopsy, a small piece of tissue is removed from your body. This tissue sample is then examined in the lab.
A needle biopsy is the safest and easiest way to remove this tissue safely from the body. To do a needle biopsy, the radiologist will insert a needle through your skin and into your tissue. A syringe or an automated needle may be used to take the tissue sample.
