• Fasting Requirements: You must fast (no solid food or colored beverages) for at least 4 to 6 hours before your appointment. This is a standard safety measure for the administration of intravenous contrast. Plain water is allowed.
• Kidney Function Clearance (Serum Creatinine): Because the contrast dye is processed and eliminated by the kidneys, a recent Serum Creatinine blood test report (usually within the last 30 days) is mandatory to ensure your renal function is sufficient to clear the dye safely.
• Allergy Disclosure: It is vital to inform the Scan4Health team if you have a known iodine allergy or have previously experienced a reaction to contrast media. Please also disclose if you have a history of asthma.
• Remove Metal Objects: You will be asked to remove all jewelry, including rings and bracelets, from your right arm. Metal causes artifacts on the scan that can obscure the fine details of the small carpal bones.
• 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 from your system.

The CE CT Hand with Wrist Right is a critical diagnostic tool used when clinical symptoms require a level of detail that exceeds routine X-rays:

Key clinical uses include:

• Vascular and Nerve Mapping: The contrast agent enables visualization of the radial and ulnar arteries as they enter the hand. This is crucial for detecting vascular malformations or areas of compression (like in severe Carpal Tunnel Syndrome).
• Tumor and Mass Characterization: If a growth or lump is identified in the soft tissues of the hand, contrast helps radiologists determine whether the lesion is a benign cyst or a more vascular tumor.
• Infection and Abscess Detection: The scan is highly sensitive in detecting deep-seated infections (such as tenosynovitis or osteomyelitis) by highlighting the inflammatory borders around affected tendons or bones.
• Inflammatory Arthritis Assessment: CE CT can detect early-stage erosions and synovial inflammation in conditions such as Rheumatoid Arthritis that may not be clearly visible on standard X-rays.
• Pre-Surgical Blueprint: For complex reconstructive surgeries, this scan provides a 3D blueprint of the patient's unique bone and vessel anatomy, allowing the surgeon to plan the most precise approach.
