What is Cone Beam CT?

Cone Beam Computed Tomography (CBCT) is an advanced imaging technique used to take detailed 3D images of the breast. Unlike traditional mammography, which provides 2D images, CBCT offers a comprehensive view of breast tissue in three dimensions, helping doctors detect and diagnose abnormalities more effectively.

How Does CBCT Work?

During a CBCT scan:

1. You will lie face down on a specially designed table with an opening for the breast being examined.

2. The breast is positioned in the imaging area, with no compression needed, making the procedure more comfortable than a mammogram.

3. The scanner rotates around the breast, capturing detailed 3D images using low-dose X-rays.

4. The entire procedure typically takes about 10 minutes.

Why Might You Need a CBCT?

CBCT is particularly useful for:

Women with dense breast tissue, where abnormalities may be harder to detect on mammograms.

Further evaluation of an abnormal finding on a mammogram or ultrasound.

Providing highly detailed images to guide biopsies or surgical planning.

Benefits of CBCT for Breast Imaging

Comfort: No breast compression is required.

Accuracy: Provides a 3D view, reducing overlap of breast tissue that can obscure abnormalities on standard mammograms.

Efficiency: Quickly captures high-resolution images.

Low Radiation Dose: Uses a lower dose of radiation compared to traditional CT scans.

Are There Any Risks?

Radiation Exposure: CBCT uses X-rays, but the radiation dose is low and considered safe.

Not a Screening Tool: CBCT is not typically used as a routine screening method but as a supplementary tool for specific cases.
