CT Guided Bone Marrow Biopsy

The soft tissue inside the hollow part of the bone is called marrow. A CT-guided bone marrow biopsy uses a needle carefully inserted into the pelvic bone to obtain a sample of bone marrow and bone. This imaging test is performed at the Turkey Lake Orlando and Maitland offices only.

At the time of the procedure, your provider will allow you the chance to ask any questions you may have. You will be asked to sign a consent for treatment. These biopsies are done using local anesthesia. Medications may also be given through your IV to help you relax. As with any surgical procedure, complications of bleeding or infections may occur, though rarely.

What to Expect

How is a bone marrow biopsy done?

A bone marrow biopsy is most commonly taken from the pelvis near your hip bone. Your doctor will tell you to lie on your side or your stomach for this procedure. He/She will clean the area with chlorhexidine. You will receive an injection of local anesthetic to numb the area where the needle will be inserted. You may feel a brief sting as the anesthetic is injected. Then your doctor will make a small incision so a hollow needle can easily pass through your skin. The needle goes into the bone and collects your marrow. You may feel a dull pain or discomfort as the needle enters your bone.

How will it feel?

If you receive a local anesthetic, you may feel a brief sting when it is injected. You also may feel some pressure when the biopsy needle is inserted. The site of the biopsy may be sore for a couple of days, and you may have a bruise. You should be able to return to work the next day.

What happens afterward?

Your doctor will apply pressure to the biopsy site to prevent bleeding and put an adhesive bandage on it. You will be given a detailed instruction sheet for post-care. Contact your doctor if you have bleeding, redness, swelling, or a fever of more than 100.5F over the next couple of days.

How to Prepare

Follow the instructions given to you by the nurse or patient care coordinator. Please notify us at the time of scheduling if you take prescription blood thinners or over-the-counter NSAIDs.
