Image-Guided Biopsy & Needle Aspiration

Biopsy procedures are performed to collect a small amount of tissue from an area of the body to determine if the tissue is benign or malignant (cancerous).

Needle aspiration procedures are performed to drain a fluid-filled cyst.

Both biopsy and aspiration are safe and minimally invasive procedures. There are various methods by which a needle biopsy can be performed. Ultrasound-guided biopsy and aspiration and Stereotactic biopsy, performed by Desert Valley Radiology, are the techniques most often used when suspicious tissue is visualized by either ultrasound or mammography.

Image-Guided Breast and Thyroid Biopsy and Aspiration

An image-guided biopsy may be performed with local anesthetic and results in minimal discomfort. No stitches are required following these procedures and most patients can resume normal daily activity immediately. Ultrasound imaging is used to assist with proper positioning of the needle. Ultrasound guided biopsy is a highly effective way to evaluate abnormal tissue within the breast and thyroid.

Stereotactic Biopsy

When a suspicious breast abnormality is detected by mammography, a Stereotactic Biopsy may be performed. Stereotactic breast biopsy is a safe and minimally invasive form of breast biopsy used to obtain tiny samples from an abnormal breast mass for examination by a pathologist. This biopsy is performed using a computer and x-ray technology to position a hollow biopsy needle. Biopsies are the only definitive way to confirm whether suspicious breast tissue is normal or abnormal.

What should you expect?

We realize a biopsy or aspiration may feel very serious to you. DVR is focused on patient comfort and an accurate diagnosis – and we make this our priority. Our specialty trained radiologists and staff make this procedure as comfortable and quick as possible.

A relative or friend may join you on the day of the procedure to lend support and drive you home if this makes you more comfortable.

During the procedure, the area of interest will be located using imaging as guidance. Once identified, the skin will be cleansed and a local anesthetic is injected into the skin and the tissue underneath the skin. Once the area is numb, the radiologist will put a very small nick in the skin for easy placement of the biopsy needle, and then a biopsy guide needle is placed and scanned for location. When the radiologist has confirmed the placement several tissue samples are taken and sent to a pathologist. The pathologist will examine the tissue cells with a microscope and send a report to your doctor.

If you have minor anxiety, you may want to ask your physician for a prescription for a mild sedative. DO NOT take this medication prior to your arrival or signing paperwork.

Following the procedure

Most biopsies performed at Desert Valley Radiology are very well tolerated with minimal pain or complication. Prior to your leaving our staff will give you follow up instructions for your post-procedural care.

When and How will you receive results?

Once your biopsy is complete, tissue samples are sent to a pathologist, who will analyze and provide your physician and Desert Valley Radiology with a diagnosis. Your physician will notify you when results of your biopsy or aspiration are available.
