Ultrasound Guided Biopsy

What is Ultrasound Guided Biopsy?

Ultrasound guided biopsy is a procedure that utilizes ultrasound guidance while performing the biopsy. The ultrasound is used to direct the biopsy needle into the region of interest and obtain a sample of tissue. 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 ultrasound guided biopsy include:

  • Breast biopsy
  • Thyroid biopsy
  • Liver biopsy
  • Lymph node biopsy
  • Biopsy of abdominal masses

Thyroid Biopsy

The common indication for thyroid biopsy is sampling of a thyroid nodule which is either palpable or visualized on prior studies. 
The procedure is done using local anesthesia. No pre procedure labs are needed and you may eat prior to the exam.

If you are currently taking blood thinner medication including Aspirin, Plavix, Coumandin or Lovenox, please notify your doctor.
For biopsy of the thyroid, very small biopsy needles are used (fine needle aspiration).  Usually 2 passes are performed and the tissue is immediately evaluated under the microscope to ensure that sufficient material was obtained.  At times additional passes are required.
The procedure takes approximately 30-45 minutes.

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 are minimal and include bleeding and infection. You may resume your normal activities following the procedure.

Liver Biopsy

The common indications for liver biopsy include random liver biopsy for evaluation of hepatitis or abnormal liver function or targeted liver biopsy of lesion which was seen on a prior imaging study.

For biopsy of focal hepatic lesions, it is important to 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 performed prior to the procedure. 
If you are currently taking blood thinner medication including Aspirin, Plavix, Coumadin or Lovenox, please notify your doctor.
For liver biopsy a core needly biopsy is performed. The number of passes will vary based on the lesion and indications.
The procedure takes approximately 30-45 minutes. 

You will be observed in the facility for an additional 2 hours following your procedure 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. You will be expected to limit your activities for 24 hours following the procedure.

Lymph Node Biopsy

The common indications for lymph node biopsy include sampling of an enlarged, abnormal appearing lymph node or a lymph node that demonstrates abnormal activity on PET scan.

The procedure is done using local anesthesia.  No pre procedure labs are needed and you may eat prior to the exam.
If you are currently taking blood thinner medication including Aspirin, Plavix, Coumandin or Lovenox, please notify your doctor.
For biopsy of the lymph node either small biopsy needles or core biopsy needles are used. This will be determined by the radiologist at the time of the exam and will be based on the location of the lymph node, adjacent structures and the suspected pathology. If lymphoma is suspected additional samples will be obtained for diagnostic purposes. The procedure takes approximately 30-45 minutes.

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 are minimal and include bleeding and infection. You may resume your normal activities following the procedure.

Biopsy of Abdominal Masses

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 performed.

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.
