This information will help you prepare for your percutaneous (pur-kyoo-tay-nee-uhs) needle biopsy procedure at Memorial Sloan Kettering (MSK).
During your percutaneous needle biopsy, your interventional radiologist will insert a needle through your skin to collect a sample of tissue. An interventional radiologist is a doctor who specializes in image-guided procedures. They may use computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, or fluoroscopy (realtime x-rays) to find the area to biopsy. The sample is sent to the laboratory for testing and evaluation.
The procedure usually takes less than 1 hour. Your interventional radiologist will explain the procedure to you and give you time to ask any questions before you sign a consent form.
Before Your Procedure
You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop taking. We have included some common examples below.
If you take medication that affects the way your blood clots, ask the doctor performing your procedure what to do. The doctor’s contact information is listed at the end of this resource. Some examples of these medications are:
drugs (NSAIDs) such as ibuprofen
(Advil®) or naproxen (Aleve®)
(a shot under your skin)
Whether they recommend you stop taking it will depend on the reason you are taking it. Do not stop taking any of these medications without talking with your doctor.
Please review the information in the resource Common Medications Containing Aspirin and Other Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). It includes important information about medications you’ll need to avoid before your procedure and what medications you can take instead.
If you take insulin or other medications for diabetes, you may need to change the dose before your procedure. Ask the doctor who prescribes your diabetes medication what you should do the morning of your procedure.
If you take any diuretics (medications that make you urinate more often), you may need to stop taking them the day of your procedure. Some examples are furosemide (Lasix®) or hydrochlorothiazide. Speak with your doctor.
You must have someone 18 years or older take you home after your procedure. If you don’t have someone to do this, call one of the agencies below. They will provide someone to accompany you home; however, there is usually a charge for this service and you will also need to provide transportation.

Your skin around the biopsy area will be cleaned and covered with a drape. You will get an injection to numb the site.
Your interventional radiologist will insert the biopsy needle and check its position with MRI, CT, ultrasound, or fluoroscopy. When the needle is in the right place, your radiologist will take the biopsy. The sample will be checked to make sure there is enough tissue. If there is enough, your interventional radiologist will remove the needle. If there is not enough, they will take another sample.
