Official Description

Computed tomography, breast, including 3D rendering, when performed, bilateral; without contrast material(s)

Common Language Description

Computed tomography (CT) of the breast is a specialized imaging technique that utilizes advanced X-ray technology and computer processing to create detailed cross-sectional images of both breasts. This procedure is particularly useful for visualizing breast tissue and identifying potential abnormalities. During the CT scan, the patient is carefully positioned on an examination table, ensuring optimal alignment for accurate imaging. An initial scan is conducted to establish the starting position, after which the actual imaging process begins. As the table gradually moves through the CT scanner, multiple X-ray beams are emitted and detected, allowing for the measurement of radiation absorption in the breast tissue. The data collected during this process is then processed by a sophisticated computer program, which generates two-dimensional (2D) images displayed on a monitor. When indicated, three-dimensional (3D) rendering is performed, enhancing the visualization of the breast structures. This may involve various techniques such as shaded surface rendering, volumetric rendering, maximum intensity projections (MIPs), fusion imaging, and quantitative analysis, all aimed at providing a comprehensive view of the breast tissue. The procedure is performed without the use of contrast material, making it a non-invasive option for breast imaging. The physician is responsible for reviewing the resulting CT images, identifying any abnormalities, and documenting a written interpretation of the findings for further evaluation and management.

1. Indications

The indications for performing a computed tomography (CT) scan of the breast include the following:

Breast Abnormalities The procedure is indicated for the evaluation of detected breast abnormalities, such as masses or calcifications, that require further investigation.
Screening CT of the breast may be utilized as a supplemental screening tool for patients with dense breast tissue or those at high risk for breast cancer.
Assessment of Treatment Response This imaging technique can be used to assess the response of breast lesions to treatment, providing valuable information on the effectiveness of therapeutic interventions.

2. Procedure

The procedure for performing a CT scan of the breast involves several key steps:

Patient Positioning The patient is positioned on the examination table in a manner that allows for optimal imaging of both breasts. Proper alignment is crucial to ensure accurate results.
Initial Scan An initial pass through the CT scanner is conducted to determine the appropriate starting position for the imaging process. This step is essential for establishing a baseline for the subsequent scans.
CT Imaging As the examination table moves slowly through the scanner, multiple X-ray beams are emitted and detected. The scanner rotates around the breast area, capturing data on the amount of radiation absorbed by the breast tissue.
Data Processing The data collected during the imaging process is processed by a computer program, which generates two-dimensional cross-sectional images of the breast. These images are displayed on a monitor for review.
3D Rendering (if performed) If indicated, complex 3D rendering techniques are applied to the 2D images. This may include shaded surface rendering, volumetric rendering, maximum intensity projections (MIPs), and fusion imaging, providing a comprehensive view of the breast structures.
Interpretation After the imaging is complete, the physician reviews the CT scan images, identifies any abnormalities, and provides a written interpretation of the findings for further clinical decision-making.

3. Post-Procedure

Post-procedure care for a CT scan of the breast typically involves minimal recovery time, as the procedure is non-invasive and does not require sedation. Patients may resume normal activities immediately following the scan. The physician will review the images and provide a written report detailing any findings, which will be communicated to the patient and their healthcare provider. It is important for patients to follow up with their physician to discuss the results and any necessary next steps based on the interpretation of the CT images.
