CT- Scan or Ultrasound-Guided Needle Biopsy
CT/ultrasound-guided needle biopsy uses a CT scanner or ultrasound equipment to help guide the radiologist to obtain a small sample (biopsy) of a suspicious or abnormal area in a tissue or organ. This procedure is performed in the Radiology Department on the 2nd floor of the hospital.
This is an outpatient procedure, requiring a 4-6 hour stay. The biopsy will help your doctor diagnose your condition.
How to Prepare for Your Procedure
Many medications, whether over-the-counter or prescription, can interfere with normal blood clotting and increase the risk of bleeding. STOP ALL aspirin and aspirin-containing products, vitamins, and herbal supplements 7 days before surgery. STOP ALL nonsteroidal anti-inflammatory products (NSAIDs) such as ibuprofen (Advil® and Motrin®), naproxen (Aleve®), piroxicam (Feldene®), sulindac (Clinoril ®), and ketoprofen 3 days before surgery. You may restart these medications the day after your biopsy. If you are taking warfarin (Coumadin®) or clopidogrel (Plavix®), ask your primary care doctor or cardiologist for instructions. Usually warfarin is stopped 5 days prior to surgery and clopidogrel is stopped 7 days before surgery.
If you have diabetes, please check with your primary doctor about what medications and dosage you should take the night before and the morning of your biopsy. If you do not have a primary doctor,please check with your surgeon.
DO NOT eat or drink after midnight the night before the biopsy; this includes gum, candy, lollipops, water, coffee, juice, etc.
The Day of Your Procedure
- Take your approved medications the morning of the procedure with a very small sip of water.
- Arrive at the hospital at your appointment time and check in at Patient Access (registration) in the main lobby, who will direct you to 2 West.
- You will have an intravenous (IV) needle placed in a vein in your arm before the procedure. You may receive IV medication for sedation or to help with anxiety or discomfort.
- You will be on the CT scan table for approximately one hour.
- The area to be biopsied will be numbed with medication. A needle will be inserted into the abnormal area to obtain a sample of tissue for the biopsy.
What You Can Expect After the Procedure
- You will recover in a special area on 2 West until you are ready for discharge.
- An x-ray may be taken after the procedure to make sure you can be safely discharged.
- You may eat immediately after the biopsy as long as the x-ray does not show any difficulties.
- There may be mild tenderness and swelling at the biopsy site. You should rest the remainder of the day after your procedure.
- You may restart all of your medications unless otherwise directed.
- For a few days after the biopsy, avoid heavy lifting, strenuous exercise, or any activity that will cause you to be out of breath.
- You will either be given a follow-up appointment with your doctor or you will be notified by phone of the results of the biopsy and the next step in your plan of care.
