The term 'full body scan' covers several different imaging modalities, each suited to different clinical questions. Understanding the distinction between CT, MRI, DEXA, and ultrasound scanning — and which is most appropriate for your situation — helps you access the right investigation efficiently rather than the most expensive one.
Types of Full Body Scanning Available in the UK
Full body CT (computed tomography) scanning uses X-ray radiation to produce cross-sectional images of the body's internal structures. A whole-body CT including chest, abdomen, and pelvis — sometimes called a 'virtual physical' — takes approximately 15 minutes and can identify lung nodules, kidney stones, aortic aneurysms, liver abnormalities, and lymphadenopathy. The radiation dose is a significant consideration, equivalent to approximately 400 chest X-rays, limiting its use as a routine screening tool.
Full body MRI scanning uses magnetic fields rather than radiation, making it safer for repeated use. It provides better soft tissue detail than CT but takes considerably longer (60–90 minutes), is more expensive, and is more prone to motion artefact. Its particular strengths include brain, spinal cord, and soft tissue tumour detection.
DEXA scanning (dual-energy X-ray absorptiometry) is the gold standard for measuring bone mineral density and diagnosing osteoporosis. Despite the name, a DEXA scan covers only the hip and lumbar spine — not a true whole-body scan in the imaging sense. Body composition DEXA scanning measures total and regional fat and lean mass and is used in sports medicine and metabolic health assessment.
When Is a Full Body Scan Clinically Indicated?
A full body scan is most clinically appropriate when a clinician has a specific diagnostic question that requires imaging — not as a standalone screening tool for healthy individuals. Examples include surveillance imaging in patients with known genetic cancer risk, assessment of unexplained symptoms that point to systemic disease, staging of a known malignancy, or following up an abnormal finding on a previous investigation.
In the UK, professional organisations including the Royal College of Radiologists advise against whole-body CT scanning in asymptomatic individuals without clinical indication, principally due to the radiation dose and the high rate of incidental findings (up to 40%) requiring further investigation at significant clinical and financial cost.
Targeted scanning based on clinical assessment is almost always more informative than whole-body scanning without a clinical question. A private GP assessment at The Vesey (from £90) can determine the most appropriate investigation for your specific symptoms and risk profile.
Accessing Private Body Scanning in Birmingham
Private body scanning in Birmingham is available through a network of accredited imaging centres accessible through The Vesey. We can coordinate referrals for CT chest/abdomen/pelvis, MRI brain and spine, abdominal ultrasound, echocardiogram, and DEXA scanning, among others.
A referral from a clinician specifying the clinical indication and sequences required is necessary for most private scanning facilities. This ensures the correct scan is performed and reported against an appropriate clinical question. A private GP consultation at The Vesey provides this request and ensures your results are interpreted in the context of your full clinical picture.
Private body scan costs in Birmingham vary by modality — targeted ultrasound scans start from approximately £200; MRI from £300; CT from £400; DEXA from £150. Full body MRI typically costs £800–£2,500. At The Vesey, we ensure scanning requests are appropriate, cost-effective, and clinically justified.
Preparing for a Body Scan
Preparation requirements differ by scan type. For most abdominal ultrasound scans, you are asked to fast for 4–6 hours. For CT scans with contrast, an allergy history and renal function check are performed beforehand. MRI requires removal of all metal objects and completion of a safety questionnaire; certain implants are contraindicated.
If your scan requires an injection of contrast dye, a member of the radiology team will explain this process and answer any questions before proceeding. Contrast reactions are rare but can occur — resuscitation facilities are present at all accredited imaging centres.
After your scan, results are sent to the requesting clinician as a written radiology report. At The Vesey, we arrange a follow-up consultation to review results with you, explain their significance, and coordinate any further management needed.

Frequently Asked Questions
What is the best type of full body scan for cancer screening?
There is no single best scan for all cancers. Different modalities are suited to different tissues. Lung cancer screening uses low-dose CT; bowel cancer is screened by colonoscopy; cervical cancer by smear test; breast cancer by mammography. Discuss your specific risk factors with a GP to determine the most appropriate screening strategy.
How much does a private body scan cost in Birmingham?
Targeted ultrasound scans start from approximately £200; abdominal CT from £400; MRI from £300; full body MRI from £800–£2,500. The Vesey can coordinate appropriate scanning referrals.
Can I get a body scan without a referral?
Some private scanning centres perform scans without a clinician's referral. However, a referral from a GP or specialist ensures the correct scan is performed, the right sequences specified, and results interpreted in clinical context.
Is a CT scan or MRI better for a body scan?
MRI provides better soft tissue detail and involves no radiation, making it preferable for brain, spine, and soft tissue assessment. CT is faster, cheaper, and better for lung and bony structures but involves significant radiation. The appropriate choice depends on the clinical question.
The right body scan is the one matched to your specific clinical question — not the most comprehensive or most expensive. At The Vesey in Birmingham, our GP team advises on appropriate imaging and coordinates referrals efficiently. Consultations from £90. Call 0121 387 3727.
