• Fasting Requirements: You are required to fast (no solid food or colored beverages) for at least 4 to 6 hours before your appointment. This is a standard safety measure for administering intravenous contrast medium. You may continue to drink plain water.
• Kidney Function Test (Serum Creatinine): Because the contrast dye is processed and eliminated by the kidneys, a recent Serum Creatinine report (dated within the last 30 days) is mandatory. This ensures your renal function is sufficient to clear the dye safely.
• Allergy Disclosure: It is critical to inform the Scan4Health team if you have a known iodine allergy or have reacted to X-ray contrast in the past. We also need to know if you have a history of asthma or severe environmental allergies.
• Remove Metal Objects: You will be asked to remove all jewelry, earrings, hairpins, and removable dental appliances (like dentures), as metal causes artifacts that can obscure critical diagnostic details of the brain.
• 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 the next 24 hours after the test. This helps your kidneys efficiently flush the contrast agent from your system.

The CE CT Head at Scan4Health is a powerful diagnostic tool utilized when clinical symptoms require a level of detail that exceeds a routine dry scan:

Key clinical uses include:

• Tumor and Lesion Characterization: Contrast enhancement is essential for identifying primary brain tumors or metastatic disease. It helps define the tumor's borders, its vascularity, and its effect on the surrounding brain tissue (edema).
• Infection and Abscess Detection: The scan is highly sensitive for identifying brain abscesses, meningitis, or encephalitis. These conditions often show ring enhancement or localized brightening on contrast, making them much easier to pinpoint.
• Vascular Abnormality Mapping: The contrast dye allows visualization of the brain’s blood vessels, helping detect aneurysms, arteriovenous malformations (AVMs), or areas of significant narrowing (stenosis).
• Blood-Brain Barrier Assessment: Many neurological conditions can disrupt the brain's protective barrier. The way the contrast dye behaves inside the skull tells the radiologist a great deal about the health of the neural environment.
• Post-Surgical Monitoring: For patients who have undergone brain surgery, the contrast-enhanced scan helps distinguish normal post-operative changes from potential complications such as infection or tumor recurrence.
