What is this test?
A CT scan uses X-rays and a computer to create detailed cross-sectional images of the neck and chest. Intravenous contrast, usually iodine-based, may be injected through a vein to help highlight blood vessels and tissues.
Why might I need this test?
This scan may be used to evaluate lumps, enlarged lymph nodes, infection, inflammation, trauma, tumors, or abnormalities involving the airway, blood vessels, lungs, and other structures in the neck and chest.
How is the test performed?
You will lie on a table while the CT scanner rotates around you and takes X-ray images. If contrast is needed, it is usually injected into a vein in your arm, and the scan typically takes only a few minutes.
How do I prepare for the test?
Follow the instructions provided by the imaging center, especially if contrast will be used. Tell the care team about any prior contrast reaction, kidney disease, thyroid disease, medications, or possible pregnancy before the scan.
Reference range
Adult males: 22-198 U/L; Females: 22-198 U/LN/A

Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate conditions such as infection, inflammation, enlarged lymph nodes, a mass or tumor, trauma, narrowing or blockage of a blood vessel, or lung disease. The radiologist interprets the images in the context of your symptoms and other test results, and your healthcare professional will explain any follow-up needed.
