What is this test?
A CT scan uses X-rays and a computer to create cross-sectional images of the neck and chest. This version is performed without injected contrast dye.
Why might I need this test?
Your clinician may order this scan to investigate lumps or swelling, enlarged lymph nodes, breathing or swallowing problems, infection, injury, or an abnormality found on another imaging test. It can also help assess the airways, lungs, thyroid region, and bones of the neck and chest.
How is the test performed?
You will lie on a CT table while an X-ray machine rotates around your head and upper body. The scan is painless, but you may be asked to remain still and briefly hold your breath. A radiologist will review the images and send the report to your ordering clinician.
How do I prepare for the test?
Fasting is usually not required. Wear comfortable clothing without metal fasteners and remove jewelry, dentures, hairpins, and other metal objects near the scanned area. Tell the imaging staff if you are pregnant or may be pregnant, and follow any specific instructions provided by your clinician.
Reference range
Adult males: 22-198 U/L; Females: 22-198 U/LN/A
No special preparation required. Inform provider of any chest pain or symptoms.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The scan may identify enlarged lymph nodes, masses, fluid collections, infection, airway narrowing, lung abnormalities, or bone changes. Findings are interpreted together with your symptoms, physical examination, and other tests, so an abnormal image does not always mean cancer. Your ordering clinician will explain the results and discuss any needed follow-up.
