Core Needle Biopsy


Core needle biopsy with stereotactic mammography

Core_needle_biopsy_with_stereotactic_mammography2Stereotactic biopsy or Stereo uses a computer to help the doctor target a specific area. It uses “stereo” x-rays (mammograms taken from multiple angles) and a special biopsy needle. This technique is rapidly replacing surgical biopsy, which requires an incision and/or surgery.

Kadlec offers two types of stereo procedures, prone and upright. The upright is using our 3D imaging and you are sitting up or lying on your side in the Mammography room. The Prone is lying on your stomach and your breast drops through an opening in the table

Both require compression for stabilization, and use a vacuum assisted device to remove tissue samples.  After consenting and obtaining pre-procedure images similar to a mammogram, the Radiologist numbs the area. Then a skin nick is done and the biopsy needle is advanced into the area.  Images are then obtained to assure the needle is in correct position. You will hear noises and samples will be removed. The samples are then imaged and then a titanium marker is placed in the biopsy area. It is normal to feel pushing and pulling sensation and slight discomfort.

Compression is applied, a sterile dressing is then put on, and finally post mammograms are obtained to show the marker in the biopsy area that was obtained.

The samples are sent to the lab at the hospital and usually the results are available in 3-4 working days.  Results will be given by your healthcare provider.


Core needle biopsy with breast MRI

During a core needle biopsy with breast MRI, you lie on your stomach on a special table and your breast fits through a hole in the table.

Before the procedure, you will be given a contrast agent through an IV. Your provider will use a local anesthetic to numb the breast area.

Your breast will be compressed like it is for a mammogram, and several MRI images will be taken. These images help your provider guide the biopsy device to the suspicious area.

A needle in the device removes a sample of tissue with a vacuum assisted probe. The needle is inserted and removed quickly.

You may feel a pushing and pulling sensation against your breast, which can cause some discomfort.
