Breast Tissue Needle Localization Guidance via Computed Tomography (CT) with Contrast

What Is a CT-Guided Breast Biopsy?

A CT-guided breast biopsy involves inserting a needle under precise imaging guidance to collect a tissue sample from your breast. This procedure is often used when a mammogram or ultrasound suggests a suspicious area but does not provide enough detail for a definitive diagnosis. The CT scan uses contrast dye to highlight blood vessels and improve visibility of the target area, ensuring the needle reaches the correct location with accuracy.

How Is This Procedure Performed?

Before the procedure, you’ll be positioned on the CT table with your breast positioned for imaging. A contrast dye may be injected to enhance visibility. The radiologist will guide the needle through the skin and into the breast tissue, using real-time CT images to confirm the needle’s placement. Local anesthesia is typically used to minimize discomfort.

Why Might This Test Be Ordered?

Your healthcare provider may recommend this test if mammograms or ultrasounds show an abnormality, such as a lump, calcification, or irregularity that needs further investigation. CT-guided biopsy is particularly useful for dense breast tissue or when other imaging methods do not provide sufficient detail for a biopsy to be safely performed.

What to Expect During Recovery?

After the procedure, you may experience mild bruising, soreness, or swelling at the biopsy site. You’ll need to rest for a short period and avoid strenuous activities. Follow your healthcare provider’s instructions for monitoring and care, including any prescribed pain relief or activity restrictions.
