• A short wait in a calm, air-conditioned lounge
• A technologist explains the scan and answers questions
• Actual scanning takes 5–15 minutes; you remain fully clothed unless contrast is used
• Immediate post-scan review to confirm image quality

• On-site radiologists for urgent reads
• Transparent pricing with no hidden costs
• Free parking and wheelchair access throughout the facility

How the Leg CT Scan Works

A CT LEG exam uses a rotating X-ray tube and detectors to capture hundreds of cross-sectional images. Powerful software stitches these slices into detailed 3-D reconstructions, allowing doctors to inspect bones, muscles, fat, and blood vessels layer by layer.

Difference Between CT Scan and CT Angiography of Legs

Standard Leg CT Scan

Captures bones, joints, and surrounding soft tissues. Ideal for trauma and chronic pain.

CT Angiography Legs

Contrast-enhanced scan of arteries from the pelvis to the foot. Detects blockages in peripheral artery disease (PAD).

CT Venography

Maps the deep veins to diagnose deep vein thrombosis (DVT) and varicose vein sources.

• Bone density measurements – evaluate osteoporosis or fracture healing
• Soft tissue evaluation – check muscle tears, abscesses, or tumours
• Vascular patency assessment – ensure arteries and veins are open

Trauma and Injury Assessment

Quickly identifies complex fractures, joint dislocations, and foreign bodies after accidents.

Chronic Leg Pain Evaluation

Uncovers occult stress fractures, arthritis, or soft-tissue lesions missed on X-rays.

Pre-Surgical Planning

3-D images guide orthopaedic surgeons in choosing plate sizes, screw angles, or bypass graft length.

Common Symptoms That Require Leg CT Scan

• Sudden swelling or redness
• Persistent leg pain with no clear cause
• Deformed limb after injury
• Non-healing ulcers on feet or ankles
• Cold, pale foot suggesting poor blood flow

Age Groups and Risk Factors

• Adults 40+ with diabetes or hypertension
• Athletes with recurrent stress injuries
• Smokers or those with high cholesterol
• Post-surgical patients monitoring grafts or hardware

• Accurate diagnosis – pinpoints problems early, preventing complications
• Non-invasive procedure – no incisions or anaesthesia needed
• Detailed 3-D imaging – rotate, zoom, and slice images to view every an

• Fractures and bone injuries – simple, compound, or hairline cracks
• Deep vein thrombosis (DVT) – blood clots in deep veins
• Peripheral artery disease (PAD) – narrowed or blocked leg arteries
• Soft tissue tumours – lipomas, sarcomas, or cysts

• Fasting – 3–4 hours if IV contrast is planned; clear fluids allowed
• Clothing and accessories – wear metal-free attire or change into hospital gown; remove jewellery
• Medication considerations – continue most meds; hold metformin on the day of contrast scan

• Doctor's prescription – mandatory for insurance and scheduling
• Medical history review – allergies, kidney disease, pregnancy status
• Kidney function tests – serum creatinine within past 4 weeks if contrast is required

• Morning appointments – ideal for fasting patients to minimise hunger and delays
• Emergency cases – 24/7 availability for trauma or suspected DVT
• Scheduled follow-up scans – coordinate with orthopaedic clinic visits for convenience

• Age criteria – infants to seniors (paediatric protocols available)
• Pregnancy considerations – only if life-saving and after risk-benefit counselling
• Weight limitations – scanner accommodates up to 200 kg; larger patients may need open MRI alternative

Check-In Process

• Present ID and prescription at reception
• Complete brief questionnaire on allergies and implants

During the Scan

• Positioning – lie supine on the table; leg immobilised with soft straps
• Duration – 5–15 minutes depending on scan type
• Instructions – hold breath for a few seconds during certain phases

Post-Scan Instructions

• Resume normal diet and activities immediately
• Drink extra water if contrast was given to flush kidneys
• Collect printed films or access digital report via Cadabams Diagnostics patient portal

• Contrast allergy screening – disclose any prior reactions to iodine or shellfish
• Pregnancy test requirements – women of child-bearing age (12–50 years) may need a quick urine test

Radiation Exposure Concerns

The effective dose for a CT LEG scan is roughly 2–4 mSv—similar to eight months of natural background radiation. Our low-dose protocols reduce exposure by up to 30 % without sacrificing image quality.

Contrast Dye Side Effects

• Mild warmth or metallic taste (common, harmless)
• Nausea or rash (<1 %)
• Severe allergic reaction (<0.05 %)

Who Should Avoid This Test

• Pregnant women (radiation risk to fetus)
• Patients with severe iodine allergy
• Individuals with eGFR <30 and contrast exam (risk of nephrotoxicity)
