Computed tomography (CT) is a process that images anatomic information from a cross-sectional plane of the body by placing the patient into the CT scanner. As mentioned under Stereotactic biopsy, CT scan is a good X-ray device to take biopsies from tissue depths. CT is used in order to guide the needle to the site of the biopsy and to provide rapid and precise localization of the needle. This procedure enables the physician to see the target area clearly and help to ensure that the tissue being removed is from the target lesion. CT can also help in characterize the tumor and aid in the estimation of malignancy. The yield of positive and accurate tissue biopsy is much higher from CT scan compared to X-rays. |
