Official Description

Computed tomography, thorax, diagnostic; with contrast material(s)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Computed tomography (CT) of the thorax is a diagnostic imaging procedure that utilizes advanced X-ray technology to create detailed images of the chest area. This procedure employs multiple, narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional images from various angles. The use of contrast material, specifically iodine dye, enhances the visibility of structures within the thorax, allowing for clearer and more precise imaging. The data collected during the scan is processed by computer software, which reconstructs the images into a three-dimensional representation of the thoracic region. This results in thin, cross-sectional slices that provide a comprehensive view of the lungs, heart, esophagus, soft tissues, and major blood vessels, including the aorta. The primary purpose of this diagnostic tool is to identify potential health issues or diseases affecting the thoracic organs, such as infections, lung cancer, pulmonary embolism, aneurysms, and metastatic cancer originating from other parts of the body. In contrast to related codes, such as CPT® 71250, which does not utilize contrast material, CPT® 71260 specifically indicates the use of contrast to enhance image quality, thereby improving diagnostic accuracy.

1. Indications

Computed tomography of the thorax with contrast material is indicated for various clinical scenarios where detailed imaging of the chest is necessary to diagnose or evaluate specific conditions. The following are the primary indications for performing this procedure:

  • Suspected Infection The procedure is often performed when there is a suspicion of infection in the lungs or surrounding structures, allowing for the identification of pneumonia or abscesses.
  • Lung Cancer CT scans are crucial in the detection and assessment of lung cancer, helping to determine the presence of tumors and their characteristics.
  • Pulmonary Embolism This imaging technique is utilized to evaluate patients for pulmonary embolism, a condition where blood clots obstruct the pulmonary arteries.
  • Aneurysms The procedure aids in the detection of aneurysms in the major blood vessels of the chest, particularly the aorta, which can be life-threatening if not diagnosed promptly.
  • Metastatic Cancer CT of the thorax is also indicated for assessing the spread of cancer from other areas of the body to the chest, providing critical information for treatment planning.

2. Procedure

The procedure for performing a computed tomography scan of the thorax with contrast material involves several key steps to ensure accurate imaging and patient safety. The following outlines the procedural steps:

  • Step 1: Patient Preparation Prior to the scan, the patient is informed about the procedure and any necessary preparations, such as fasting or discontinuing certain medications. The healthcare provider assesses the patient's medical history, particularly any allergies to contrast material, especially iodine-based dyes.
  • Step 2: Positioning the Patient The patient is positioned on the CT scanner table, typically lying on their back. Proper alignment is crucial to obtain clear images of the thorax. The technician may use straps or pillows to help the patient maintain the correct position during the scan.
  • Step 3: Administration of Contrast Material Once the patient is in position, an intravenous (IV) line is established to administer the contrast material. The iodine-based dye is injected into the bloodstream, enhancing the visibility of blood vessels and tissues in the thoracic region.
  • Step 4: Performing the CT Scan The CT scanner is activated, and the patient is moved through the machine. As the scanner rotates, it captures multiple X-ray images from various angles. The patient may be instructed to hold their breath briefly during the imaging to minimize motion artifacts.
  • Step 5: Image Reconstruction After the scan is complete, the collected data is processed by computer software, which reconstructs the images into detailed cross-sectional slices of the thorax. These images are then reviewed by a radiologist for interpretation.

3. Post-Procedure

After the computed tomography scan with contrast material, the patient is monitored for any immediate reactions to the contrast dye, particularly if they have a history of allergies. The healthcare provider may provide instructions regarding hydration to help flush the contrast material from the body. Patients are typically advised to resume normal activities unless otherwise directed. Follow-up appointments may be scheduled to discuss the results of the scan and any further diagnostic or treatment plans based on the findings.
