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

Computed tomography (CT) of the breast is a diagnostic imaging procedure that utilizes advanced X-ray technology and computer processing to create detailed cross-sectional images of the breast on one side. This procedure is particularly useful for evaluating breast abnormalities and is performed unilaterally, meaning it focuses on one breast. During the CT scan, the patient is carefully positioned on an examination table, which is then moved through the CT scanner. An initial scan is conducted to establish the starting position, after which the actual imaging process begins. As the table progresses through the scanner, multiple X-ray beams and detectors rotate around the breast, capturing data on the amount of radiation absorbed by the tissues. This information is then processed by a computer program to generate two-dimensional (2D) images that are displayed on a monitor. When indicated, three-dimensional (3D) rendering techniques are applied to enhance the visualization of the breast tissue. These techniques may include shaded surface rendering, volumetric rendering, maximum intensity projections (MIPs), fusion imaging, and quantitative analysis, providing a comprehensive view of the breast's structure. The procedure may start without the use of intravenous contrast material, but if necessary, contrast agents can be administered afterward to obtain additional imaging sections. The physician is responsible for reviewing the CT images, identifying any abnormalities, and documenting a written interpretation of the findings for further evaluation and management.
