• Fasting Requirements: You must fast (abstain from solid foods and colored liquids) for at least 4 to 6 hours before your appointment. This is a safety measure for the administration of intravenous contrast; plain water is permitted.
• Kidney Function Test (Serum Creatinine): A recent Serum Creatinine blood test report (usually within the last 15 to 30 days) is mandatory. Since the kidneys process the contrast dye, we must ensure your renal function is sufficient to clear it safely.
• Allergy Disclosure: Please inform the Scan4Health team if you have a known iodine allergy or have previously reacted to contrast media.
• Remove Metal Objects: You will be asked to remove earrings, hearing aids, spectacles, and hairpins. Metal creates artifacts (streaks) that can obscure the microscopic details of the inner ear.
• 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 8–10 glasses of water over 24 hours after the test to help your kidneys efficiently flush the contrast agent.

The CE CT Temporal Bone at Scan4Health Gurgaon is a powerful tool for investigating clinical symptoms related to hearing, balance, and facial movement:

Key clinical uses include:

• Tumor Characterization: Contrast is essential for identifying and staging tumors such as Acoustic Neuromas (vestibular schwannomas) or Glomus tumors, as it shows their blood supply and extent.
• Chronic Otitis Media & Cholesteatoma: While the bone damage is seen on a standard CT, contrast helps identify associated complications such as brain abscesses or inflammation of the surrounding membranes (meningitis).
• Vascular Tinnitus: It helps identify abnormal blood vessel connections or dehiscent (exposed) vessels that might be causing a pulsing sound in the ear.
• Facial Nerve Evaluation: The scan helps visualize the facial nerve pathway to detect tumors or inflammation such as complications of Bell’s Palsy that could cause facial drooping.
• Post-Surgical Monitoring: Used to check the placement of cochlear implants or to evaluate the success of mastoid surgeries.
