• Fasting Requirements: You are required to fast (abstain from food and colored drinks) for at least 4 to 6 hours before the scan. This is a safety precaution for administering the intravenous contrast medium. You may continue to drink plain water to stay hydrated.
• Kidney Function Test (KFT/Serum Creatinine): Since the contrast dye is processed and eliminated by the kidneys, a recent Serum Creatinine report (usually within the last 30 days) is mandatory. This ensures your kidneys are functioning sufficiently to clear the contrast safely.
• Allergy Disclosure: It is vital to inform the Scan4Health team if you have a known iodine allergy or have had a previous adverse reaction to X-ray contrast media. We also need to know if you have a history of asthma or severe food allergies.
• Clothing and Jewelry: Wear loose, comfortable clothing. You will be asked to remove any metal objects, such as jewelry, anklets, or clothing with metal zippers/buttons from the waist down, as metal can cause "artifacts" (blurring) on the CT images.
• Medication Review: Inform the staff if you are taking Metformin (for diabetes). In some cases, you may be advised to temporarily pause this medication for 48 hours following the contrast injection.
• Hydration Post-Scan: Plan to drink plenty of water following the procedure to help your body flush out the contrast dye efficiently.

The CE CT Ankle Left is specifically indicated when a higher level of detail is required beyond what a plain X-ray or non-contrast CT can provide. At Scan4Health, this scan serves several critical clinical purposes:

Key clinical uses include:

• Vascular and Inflammatory Mapping: The contrast dye enables clear visualization of blood vessels. This is crucial for diagnosing vascular malformations, peripheral artery disease in the lower limb, or identifying areas of intense inflammation (synovitis) within the ankle joint.
• Tumor and Mass Evaluation: If a lump or mass is detected in the soft tissues of the left ankle, the enhancement pattern (how contrast moves through the mass) helps radiologists determine whether the growth is likely benign or malignant.
• Complex Fracture Assessment: In cases of severe trauma, the CE CT helps evaluate the blood supply to bone fragments (to ensure bone viability) and identifies associated hematomas or active bleeding in surrounding tissues.
• Infection Detection: The scan is highly effective at identifying abscesses or osteomyelitis (bone infection) by highlighting the rim enhancement typically seen in infected or necrotic tissue.
• Pre-Surgical Planning: For complex reconstructive surgeries, this scan provides a 3D blueprint of the patient’s unique anatomy, allowing surgeons to navigate around critical vessels and nerves with higher precision.
