• Fasting Requirements: You must fast (abstain from all solid foods) for at least 4 to 6 hours before the test. You should stay well-hydrated with plain water.
• Kidney Function (Serum Creatinine): A recent serum creatinine test (within the last 30 days) is mandatory. The high-flow contrast used in angiography requires healthy kidney function for safe elimination.
• Allergy Disclosure: Inform our team if you have a history of asthma or allergies to iodine or X-ray contrast.
• Metal Removal: You must remove all necklaces, earrings, and removable dental work. Metal creates streaking artifacts that can hide critical vascular details.
• Medication: Continue regular medications, but inform us if you take Metformin. You may need to pause it for 48 hours after the scan.
• Post-Scan Hydration: Drink at least 2 liters of water over the 24 hours following your scan to help flush the contrast dye from your system.

The CE CT Neck Angiography is a vital diagnostic tool for cerebrovascular health:

Key clinical uses include:

• Carotid Artery Stenosis: It accurately measures the degree of narrowing due to plaque buildup (atherosclerosis), helping doctors determine whether a patient needs a stent or surgery to prevent stroke.
• Stroke & TIA Evaluation: For patients experiencing mini-strokes or sudden neurological symptoms, CTA is used to find the source of the blockage or blood flow restriction.
• Arterial Dissection: It is the primary tool for detecting tears in the lining of the neck arteries, a common cause of stroke in younger adults, often following trauma or sudden neck movement.
• Aneurysm & Malformation Detection: It identifies bulges (aneurysms) or abnormal connections between arteries and veins (AVMs) that could potentially rupture.
• Pre-Surgical Planning: Provides a 3D blueprint for surgeons planning vascular repairs or tumor removals near major blood vessels.
