• Fasting Requirements: You must fast (abstain from all solid foods and colored liquids) for at least 4 to 6 hours before your appointment. This is a standard safety protocol for the administration of intravenous contrast. You may continue to drink plain water.
• Kidney Function Test (Serum Creatinine): Since the contrast dye is eliminated by the kidneys, a recent Serum Creatinine report (dated within the last 30 days) is mandatory. This ensures your kidneys are functioning optimally to clear the dye safely.
• Allergy Disclosure: It is vital 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 food allergies.
• Remove Metal Objects: You will be asked to remove your shoes, socks, and any metal items, such as anklets, toe rings, or clothing with metal zippers/buttons, from the waist down. Metal causes artifacts on the scan that can blur important diagnostic details.
• Medication Review: Inform our staff if you are taking Metformin for diabetes. You may be advised to temporarily pause this medication for 48 hours after 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 Foot Left is a powerful diagnostic tool used when standard X-rays or non-contrast scans do not provide sufficient detail. Its clinical utility includes:

Key clinical uses include:

• Vascular and Inflammatory Mapping: The contrast dye highlights the blood vessels in the foot. This is critical for diagnosing vascular diseases, identifying areas of intense inflammation (synovitis), or evaluating blood flow in diabetic patients.
• Tumor and Mass Evaluation: If a lump or mass is detected in the soft tissues of the left foot, the enhancement pattern of the contrast helps the radiologist determine if the growth is likely a benign cyst or a potentially malignant tumor.
• Complex Fracture and Bone Viability: In cases of severe trauma, the CE CT helps evaluate the blood supply to bone fragments (ensuring bone viability) and identifies active bleeding or hematomas in the surrounding muscles.
• Infection and Abscess Detection: The scan is highly sensitive for identifying deep-seated infections or osteomyelitis (bone infection), showing rim enhancement around infected areas that are not visible on standard X-rays.
• Tendon and Ligament Assessment: While MRI is commonly used for soft tissues, a CE CT provides excellent detail of tendon enhancement, helping identify chronic tears or severe tendinosis at the plantar fascia or Achilles tendon insertion.
