• Fasting Requirements: You are required to fast (no solid food or colored beverages) for at least 4 to 6 hours before the scan. This is a safety measure for the IV contrast administration. Plain water is permitted.
• Kidney Function Test (Serum Creatinine): A recent Serum Creatinine report (within the last 30 days) is mandatory. This ensures your kidneys can safely process the IV contrast dye.
• Wound Preparation: Please do not apply any heavy creams, powders, or tight bandages to the sinus opening on the day of the test. Our clinical team will clean the area before the procedure.
• Allergy Disclosure: Inform the Scan4Health team if you have a known allergy to iodine or X-ray contrast.
• Remove Metal: Depending on the location of the sinus tract, you may be asked to remove jewelry or clothing with metal fasteners from that specific body region.
• Medication Review: If you take Metformin for diabetes, you may need to pause it for 48 hours following the test.
• Post-Scan Care: Plan to drink 8–10 glasses of water for 24 hours after the test to help your kidneys flush out the contrast media.

The CE CT Sinogram at Scan4Health is a critical diagnostic tool for managing complex, non-healing wounds:

Key clinical uses include:

• Defining the Tract Route: It accurately identifies the sinus tract's length, width, and direction, indicating whether it is a simple straight line or a complex, branching network.
• Identifying the Source: The scan helps find the origin of the tract, such as a hidden abscess, a retained surgical foreign body (like a suture), or a piece of infected bone (sequestrum).
• Visualizing Organ Involvement: It determines if the tract connects to internal organs, the bowel, or the bladder, which is vital for preventing serious complications.
• Vascular Proximity: By using IV contrast simultaneously, the scan shows how close the tract is to major blood vessels, allowing surgeons to avoid these areas during treatment.
• Surgical Blueprinting: It provides a 3D model that acts as a blueprint for Excision of Sinus Tract surgeries, significantly reducing the risk of the tract returning.
