Private CT Scan · Chest
A private chest CT scan produces detailed cross-sectional images of the lungs, airways, mediastinum, heart and great vessels. It is the definitive investigation for persistent respiratory symptoms, pulmonary nodules, and pleural disease.

About this scan
CT (Computed Tomography), also called a CAT scan, uses X-rays taken from multiple angles around the body, processed by a computer to create detailed cross-sectional images. It is faster than MRI (often under 10 minutes) and excellent at imaging bones, blood vessels, lungs, and abdominal organs.
CT is particularly useful for diagnosing chest and abdominal conditions, detecting internal injuries, and planning surgery. Some CT scans use an injected contrast agent (a dye) to improve visibility of blood vessels and organs. While CT does involve ionising radiation, modern scanners are highly efficient and doses are carefully managed.
Key facts
The process
You'll complete a short questionnaire about allergies and medical history. If contrast is needed, a cannula is inserted into a vein.
You'll lie on the CT table. The radiographer explains what will happen and positions you correctly for the scan.
The table moves through the CT ring while it rotates around you. It's completely painless. The whole scan typically takes 5–15 minutes.
A consultant radiologist produces your written report, usually within 48 hours, delivered to your ScanBook portal.
Before your scan
You may be asked to fast for 4–6 hours before CT scans involving contrast dye.
Inform the radiographer of any allergies, particularly to iodine or previous contrast reactions.
Remove metal objects: jewellery, belts and some clothing may need to be removed.
If you are or might be pregnant, inform the centre immediately before booking.
Drink plenty of water after your scan if contrast dye was used to aid kidney clearance.
FAQs
What does a chest CT scan show?
Chest CT provides detailed images of the lungs, airways, heart, mediastinum (central chest) and major blood vessels. It detects nodules as small as 1–2mm, identifies infection, fibrosis, effusions, and vascular abnormalities.
Is chest CT the same as a lung cancer screening scan?
Low-dose CT (LDCT) is the recommended tool for lung cancer screening in high-risk individuals. A standard diagnostic chest CT provides more detail and is used when symptoms are present. Ask our team which protocol is right for you.
Will I need contrast dye?
For vascular assessment (e.g. pulmonary embolism, CTPA) an intravenous contrast injection is required. Standard lung imaging does not need contrast. Your booking confirmation will confirm which type of scan is required.
How long does a chest CT take?
The scan itself takes 5–10 minutes. With preparation and positioning, your appointment will last approximately 30 minutes.
Is CT safe, and how much radiation is involved?
Modern CT scanners use significantly less radiation than older machines. A chest CT is roughly equivalent to 1–2 years of background radiation. Your radiographer follows strict "as low as reasonably achievable" (ALARA) principles.
What is contrast dye and is it safe?
Contrast dye (iodine-based) is injected to enhance blood vessels and certain organs. It's generally very safe but can cause rare allergic reactions. Inform us of any previous contrast reactions or iodine allergies.
How long does a CT scan take?
The scanning itself takes just 5–15 minutes. Allow 30–60 minutes total for the appointment including preparation and post-scan monitoring if contrast was used.
