CT Scan
A lump you can feel in your neck, or lymph nodes that stay swollen longer than an infection would explain, is one of the more common reasons this scan gets ordered - and unlike the combined face-and-neck study, it focuses only on the neck itself. For a palpable neck mass outside the thyroid or parotid gland, CT of the neck with intravenous contrast is generally considered appropriate imaging to help work out whether it's a normal structure, an infection, or something needing a biopsy. Contrast matters here because it highlights how a lymph node or mass takes up blood flow, part of how a radiologist judges whether it looks reactive or concerning. This scan also covers neck trauma.
This scan images the soft tissue, lymph nodes, muscles, and airway of the neck in cross-section, without covering the face. It shows the size, shape, and enhancement pattern of any mass or enlarged lymph node. Your doctor interprets this alongside a physical exam and how long the lump has been present.
Unlike the combined face-and-neck study, this scan images only the neck - its soft tissue, lymph nodes, salivary glands other than the parotid, muscles, and airway structures. It's the more targeted option when a problem is clearly limited to the neck.
Most neck lumps are enlarged lymph nodes, and while many are caused by ordinary infections that settle on their own, a lump that persists, grows, or doesn't fit a clear infectious pattern is generally checked with imaging. For a palpable mass outside the thyroid or parotid gland, CT of the neck, done with or without contrast depending on the case, is considered an appropriate first imaging step.
Contrast dye highlights blood flow, which helps a radiologist judge whether a lymph node or mass looks reactive, infected, or more concerning, and it improves visibility of the vessels running through the neck.

Ask your doctor whether contrast applies to your specific referral.
This scan covers only the neck, while the combined study extends up to include the facial bones as well. Your doctor chooses this one when the concern is clearly limited to the neck.
Often, yes, since contrast makes lymph nodes and soft-tissue masses easier to evaluate. Your doctor decides based on your specific symptoms.
It can show features that raise or lower concern, but a definite diagnosis usually needs a biopsy. Your doctor interprets the scan alongside your exam and history.
Thyroid lumps are generally evaluated differently, often starting with ultrasound. This CT is more commonly used for neck masses outside the thyroid and parotid gland.
This page is general information about the test, not medical advice. Your own report's reference ranges apply — please discuss your results with your doctor.
Yes, it uses X-rays, though it covers a smaller area than a combined face-and-neck study.
That's a decision for your doctor based on how the lump behaves - whether it's growing, persistent, or came with other symptoms like fever or weight loss. There's no fixed timeline that applies to everyone.
Mention any allergies to contrast dye, kidney problems, or if you're pregnant or think you might be. Ask your doctor or the centre about any other preparation specific to your appointment.
