CT Brain & Angiography

When it comes to spotting problems in the blood vessels of your brain and neck, CT Brain & Angiography is the fastest, least-invasive way to get clear answers. At Cadabams Diagnostics, we use cutting-edge 128-slice CT scanners that complete the entire study in under 15 minutes—no hospital stay, no overnight fasting, and reports ready the same day.

CT angiography (CTA) head and neck is a specialised scan that uses X-rays and an iodine-based contrast dye to create 3-D pictures of the arteries supplying your brain and face. It shows:

• Blockages or narrowing
• Aneurysms or bulges
• Arterial malformations Cadabams Diagnostics combines this with a CT Brain scan to capture both the brain tissue and its blood vessels in one seamless session.

1. Standard CTA Head & Neck – entire carotid and vertebral system
2. CT Brain Perfusion + Angiography – adds blood-flow maps in stroke work-up
3. CT Venogram (CTV) – focuses on cerebral veins and sinuses Cadabams offers all three on the same scanner platform.

• Scan range: Skull vertex to aortic arch
• Slice thickness: 0.625 mm for razor-sharp images
• Contrast volume: 60–80 ml at 4–5 ml/s
• Radiation dose: <1 mSv (lower than a round-trip Delhi–Mumbai flight)

• Rule out acute stroke or brain haemorrhage
• Detect carotid stenosis before symptoms appear
• Evaluate arteriovenous malformations (AVMs)
• Assess traumatic vascular injury after accidents

Common Scenarios

• Sudden, severe headaches or suspected stroke
• Dizziness, vision loss, or transient ischaemic attack (TIA)
• Follow-up after head injury or brain surgery
• Screening for aneurysm if there’s a family history
• Pre-operative planning for ENT or neurosurgery

• Speed: Entire study in 10–15 minutes
• Accuracy: 97 % sensitivity for aneurysms >2 mm
• Non-invasive: No catheter insertion into the groin
• Same-day reports: Digital access via Cadabams patient portal

• Fasting: 2–4 hours before scan (clear fluids allowed).
• Hydration: Drink 500 ml water the night before to protect kidneys.
• Clothing: Wear loose, metal-free attire; lockers provided.

• Recent creatinine report (within 4 weeks)
• List of current medications (esp. metformin)
• Pregnancy test if applicable

• Emergency: Immediately after stroke symptoms
• Elective: Early morning slots (7 am–10 am) for faster contrast clearance and same-day reporting

• Age: 12 years and above
• Weight: Up to 150 kg on our wide-bore scanner
• Contraindications: Severe iodine allergy, pregnancy, uncontrolled hyperthyroidism

1. Check-in at Cadabams Diagnostics—digital registration.
2. IV line placed in the arm for contrast.
3. Positioning—you lie head-first on the scanner table.
4. Scout image confirms correct area.
5. Contrast injection—warm feeling for 15–20 seconds.
6. Scan—hold still for 5–7 seconds; machine is quiet.
7. Observation—10-minute post-scan monitoring, then discharge.

• Discontinue metformin 48 hours prior if kidney function is borderline.
• Inform staff about shellfish or previous contrast reactions.
• Bring a companion if you have claustrophobia or mobility issues.

Minimal Risks

• Radiation exposure is low with our modern low-dose protocols.
• Contrast allergy occurs in <1 % of cases; we screen and pre-medicate when needed.

Limitations

• Not ideal for very obese patients (>150 kg) with older CT tables.
• Cannot fully replace catheter angiography for tiny (<1 mm) vessel details.
