What is CT Scan?
Usmanpura Imaging Centre
CT scan is an advanced low-radiation diagnostic procedure that can be performed over the whole body — from head to toe. CT scan for the brain helps diagnose haemorrhage, stroke, and other brain conditions with speed and precision.

Contrast & Non-Contrast CT
1. Non-Contrast CT Scan:
Walk-in, walk-out — completed in just 2–3 minutes. No pre-diagnostic preparation required.
2. Contrast CT Scan:
Before the procedure, a serum creatinine blood test is required to confirm normal kidney function. The contrast dye can adversely affect patients with pre-existing kidney disease.

What is a CT Scan?
A CT scan (Computed Tomography) uses special X-ray equipment and computers to produce detailed cross-sectional images of the body — bones, organs, blood vessels, and soft tissues. Unlike a flat 2D X-ray, CT gives 3D slice-by-slice views for far greater diagnostic accuracy.
CT is the fastest diagnostic imaging scan available — completing in 2–10 minutes. It is ideal for emergencies, head trauma, chest, abdomen, and cancer staging where speed and accuracy are both critical.
Types of CT Scans Available at UIC — Ahmedabad
From Brain CT to Whole Body CT — every type at one place, with advanced multi-slice scanners and expert radiologists.
CT Scan With Contrast vs Without Contrast
Our radiologist will advise which type is appropriate for your condition.
- Walk-in, walk-out — no preparation needed
- Completed in just 2–3 minutes
- Best for bones, brain trauma, kidney stones
- No injection — completely non-invasive
- Suitable for kidney disease patients
- Lower cost, faster report
- 4–6 hours fasting required before scan
- Serum creatinine blood test mandatory
- Best for tumours, infections, vascular disease
- Contrast dye injected through a vein
- Avoid if kidney function is abnormal
- More detailed — better for soft tissue lesions
Your doctor or our radiologist will advise whether contrast is needed based on your clinical indication and symptoms.

CT Scan Safety — Who Should Take Precautions?
CT scan is a low-radiation, clinically safe procedure. However, certain patients need special attention.
- Adults and elderly — no age restriction
- Emergency patients — fastest scan for trauma & stroke
- Patients with pacemakers or metal implants (unlike MRI)
- Cancer patients needing staging or monitoring
- Children — with special paediatric low-dose protocol
- Claustrophobic patients — CT bore is shorter and wider than MRI
- Pregnant women — CT should be avoided unless absolutely necessary
- Patients with known contrast dye allergy — inform radiologist
- Kidney disease patients — creatinine test required before contrast CT
- Diabetic patients on Metformin — discuss with doctor before contrast
- Breastfeeding mothers — short interruption may be advised after contrast
- Asthma or severe allergies — inform staff before contrast injection
Note: Always inform our staff of your complete medical history. Our radiologists carefully assess every patient before administering contrast dye.

CT Scan vs MRI — Which One Do You Need?
Both are important diagnostic tools — here's how they differ and when each is recommended.
| Feature | CT Scan | MRI Scan |
|---|---|---|
| Radiation | Low-dose X-ray radiation | ❌ Zero radiation — magnetic fields |
| Scan Speed | ⚡ Very fast — 2 to 10 minutes | Slower — 20 to 60 minutes |
| Best For | Bones, chest, abdomen, emergency, blood vessels | Brain detail, spinal cord, joints, soft tissues |
| Emergency Use | ✔ Ideal — fastest choice for stroke, trauma | Less suitable — takes longer |
| Noise Level | 🔇 Quiet — minimal noise | Loud — banging sounds (headphones provided) |
| Pregnant Women | Avoid unless essential | ✔ Safe — zero radiation |
| Metal Implants | ✔ Generally compatible | Consult radiologist — magnetic field concern |
| Cost | Moderate | Higher |
Your doctor recommends the right scan based on your specific condition and clinical need.
