CT Scan of Brain & Coronals

A CT SCAN OF BRAIN & CORONALS is a painless, non-invasive imaging test that captures detailed cross-sectional images of the brain from front-to-back (coronal) and side-to-side (axial) views. At Cadabams Diagnostics, we use advanced 128-slice CT scanners to deliver sharp, high-resolution images in under 10 minutes—helping doctors detect and treat neurological conditions quickly.

• Definition: A coronal CT scan slices the brain vertically from ear to ear, providing a top-down view of the frontal and occipital lobes.
• Technology used: Multi-detector CT (MDCT) with low-dose radiation protocols.
• Distinguishing feature: Complements axial slices to give 3D-like clarity for better diagnosis.

1. Non-contrast CT – Quick emergency scan for bleeding or fractures.
2. Contrast-enhanced CT – Highlights tumors, infections, or vascular malformations.
3. CT angiography (CTA) – Evaluates blood vessels for aneurysms or blockages.

• Slice thickness: 0.625–1.25 mm
• kVp: 100–120
• mAs: 150–250 (auto-modulated)
• Reconstruction interval: 50 % overlap
• Field of view (FOV): 22–25 cm

• Rule out intracranial hemorrhage post-injury
• Detect skull fractures after road accidents
• Evaluate sinusitis or mastoiditis
• Plan neurosurgical interventions

• Speed: Completed in <10 minutes
• Accuracy: 95 % sensitivity for detecting acute stroke
• Comfort: Open-bore design reduces claustrophobia
• Availability: 24×7 at Cadabams Diagnostics emergency wing

• Stroke (ischemic & hemorrhagic)
• Brain tumors (meningioma, glioma)
• Traumatic brain injury (contusion, hematoma)
• Hydrocephalus and midline shift
• Chronic sinus disease

• Fasting: Not required for non-contrast scans; 4-hour fast if contrast is planned.
• Clothing: Wear loose, metal-free attire.
• Valuables: Remove earrings, hairpins, and piercings.
• Medications: Continue routine medicines unless advised otherwise.

• Doctor’s prescription or emergency requisition
• Recent serum creatinine report (if contrast is used)
• Allergy checklist form filled at reception

• Emergency cases: Immediately, day or night.
• Elective cases: Morning slots reduce waiting time.
• Post-injury: Within the golden hour for best treatment outcomes.

1. Registration: Verify ID and consent.
2. Positioning: Lie supine, head in the padded cradle.
3. Scout scan: Quick topogram to set boundaries.
4. Main scan: Table moves every 2–3 seconds; hold breath for <5 seconds.
5. Contrast injection (if needed): Via auto-injector, 70–100 ml at 4 ml/sec.
6. Post-scan observation: 15 minutes for contrast allergy watch.

• Inform about pregnancy or breastfeeding.
• Disclose renal impairment history for contrast plans.
• Bring a responsible adult if sedated.

• Radiation exposure: Equivalent to ~8 months of natural background radiation—well within safe limits.
• Contrast allergy: Rare (0.04%). Inform staff of iodine or shellfish allergy.
• Limitation: Soft-tissue detail slightly lower than MRI; however, bone and acute bleeding are clearer on CT.
