CT Guided Biopsy

What is CT Guided Biopsy?

CT guided biopsy is a procedure that utilizes CT guidance while performing the biopsy. The CT is used to direct the biopsy needle into the region of interest so that a tissue sample may be obtained. 

This procedure is done by specially trained radiologists. It is usually done as an outpatient procedure.

What are some common uses of the procedure?

The most common uses of CT guided biopsy include:

Lung Biopsy

The most common indication for lung biopsy is a lung nodule which was seen on prior imaging study and may represent cancer.
Please bring a copy of the outside study if it was not performed at our institution. This will allow us to target the appropriate lesion.
The procedure is usually done using local anesthesia. Pre procedure blood tests are needed including PT/ PTT and Platelets. These tests will assess your risk for bleeding.  Your physician will refer you to have those tests done prior to the procedure. 

If you are currently taking blood thinner medication including Aspirin, Plavix, Coumadin or Lovenox, please notify your doctor.
The procedure takes about 60 minutes. You will receive local anesthetic to numb the skin. You may feel some pressure when the biopsy needle is inserted. The area will become numb within a short time.

You may be given a mild sedative prior to the biopsy, and in addition, sedation or relaxation medication may be given intravenously during the procedure if needed.

You will be asked to remain still and not to cough during the procedure. You also will be asked to hold your breath multiple times during the biopsy. It is important that you try to maintain the same breath-hold each time to ensure proper needle placement.

The risks of the procedure includes infection, bleeding, coughing up blood and pneumothorax (an air leak from the punctured lung into the chest cavity). Signs of a pneumothorax include shortness of breath, difficulty in catching your breath and rapid pulse
(heart rate), sharp chest or shoulder pain with breathing, and/or blueness of the skin. If you experience any of these symptoms, go to the nearest Emergency Room and contact your physician as soon as possible.

You will be observed in the facility for an additional 2-4 hours following the biopsy to ensure that there are no complications.
The specimen is sent to the pathology lab for evaluation. The referring physician will receive the results of the biopsy within 4-5 days.

Biopsy of abdominal masses can be done using ultrasound or CT guidance. If the lesion is not well seen using ultrasound, CT guidance will be utilized.

The procedure is usually done using local anesthesia. Pre procedure blood tests are needed including PT/ PTT and Platelets. These tests will assess your risk for bleeding. Your physician will refer you to have those tests done prior to the procedure. 

If you are currently taking blood thinner medication including Aspirin, Plavix, Coumadin or Lovenox, please notify your doctor. The procedure takes approximately 30-45 minutes. 

You will be observed in the facility for an additional 2 hours to ensure that there are no complications.
The specimen is sent to the pathology lab for evaluation. The referring physician will receive the results of the biopsy within 3-5 days. The risks of the procedure include bleeding and infection.
