What is this test?
A neck CT is an X-ray-based imaging test that creates detailed cross-sectional pictures of the neck. The version without contrast does not require intravenous contrast dye.
Why might I need this test?
A CT scan of the neck may be ordered to investigate swelling, a lump, pain, infection, airway symptoms, trauma, or an abnormality found during another examination or imaging study. It can also help assess lymph nodes and structures such as the thyroid, salivary glands, and throat.
How is the test performed?
You will lie on a padded table while an X-ray machine rotates around your head and neck. The scan is usually painless and takes a short time; a technologist may ask you to remain still and hold your breath briefly.
How do I prepare for the test?
No contrast-related preparation is generally needed. Follow the imaging center's instructions, remove jewelry and other metal near your head and neck, and tell the staff if you are pregnant or may be pregnant.
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 reveal enlarged lymph nodes, cysts, tumors, inflammation, infection, stones, airway narrowing, or injury. If an abnormality requires more precise evaluation, the radiologist may recommend additional imaging or a CT scan with intravenous contrast.
