A CT Guided Biopsy is a procedure by which a radiologist uses a specific needle to obtain a tissue specimen from an organ or suspected tumor mass. The needle is guided while being viewed by the radiologist on a CT scan.
The radiologist performing your biopsy may use a CT scanner to observe and follow the biopsy needle as it approaches and reaches the targeted tissue within your body. CT imaging significantly shortens the amount of time it takes to complete the biopsy and increases the accuracy of your diagnosis.
A CT Guided Biopsy provides images that help guide the tools or equipment necessary to perform the biopsy to the appropriate area of the body. This scan requires that you lie flat on your back. Prior to the biopsy, the nurse will start an IV and give medication to relax you during the procedure. You will be placed on a cardiac monitor so that the nurse can monitor your vital signs closely. After the biopsy, you will be kept for several hours to monitor you for any complications. If no complications arise, the radiologist will discharge you to go home. You must bring someone with you to drive you home after the procedure. The nurses will give you a call the next day after your biopsy to check on you. You will also be given discharge instructions before you are discharged from the hospital.
