• Fasting Requirements: You are required to fast (abstain from solid foods and colored beverages) for at least 4 to 6 hours before your appointment. This is a standard safety measure for the administration of intravenous contrast. You may continue to drink plain water.
• Kidney Function Clearance (Serum Creatinine): Because the contrast dye is processed and eliminated by the kidneys, a recent Serum Creatinine blood test report (usually within the last 30 days) is mandatory to ensure your renal function is optimal.
• Allergy Disclosure: It is critical to inform the Scan4Health team if you have a known iodine allergy or have previously experienced a reaction to contrast media. Please also disclose if you have a history of asthma.
• Remove Metal Objects: You will be asked to remove all jewelry, earrings, necklaces, and removable dental appliances (like dentures), as metal creates artifacts that can obscure the fine details of the neck structures.
• Medication Review: Inform our clinical staff if you are taking Metformin for diabetes. You may be advised to pause this medication for 48 hours following the contrast injection.
• Post-Scan Hydration: Plan to drink plenty of water (8–10 glasses) for 24 hours after the test to help your kidneys efficiently flush the contrast agent from your system.

The CE CT Neck at Scan4Health is a critical diagnostic tool utilized when clinical symptoms require a level of detail that exceeds a routine physical exam or ultrasound:

Key clinical uses include:

• Lymph Node Assessment: Contrast is essential for identifying enlarged lymph nodes (lymphadenopathy) and determining if they show signs of infection, inflammation, or malignancy (cancer).
• Tumor and Mass Characterization: The scan is highly effective at defining the borders of tumors in the thyroid, salivary glands, or throat. Contrast enhancement helps show the tumor's relationship to major nerves and blood vessels.
• Infection and Abscess Mapping: The scan can pinpoint deep-seated neck infections or abscesses by highlighting the inflammatory borders, which is vital for planning drainage or antibiotic therapy.
• Vascular Evaluation: The contrast dye allows visualization of the carotid arteries and jugular veins, helping detect narrowing (stenosis), blockages, or vascular malformations.
• Upper Airway and Esophagus Assessment: It provides detailed views of the larynx and the upper esophagus, helping identify obstructions, foreign bodies, or structural abnormalities.
