• Fasting Requirements: You must fast (abstain from solid foods and colored liquids) for at least 4 to 6 hours before your appointment. This is a safety measure for the administration of intravenous contrast; plain water is permitted.
• Kidney Function Test (Serum Creatinine): A recent serum creatinine test report (usually within the last 30 days) is mandatory. The kidneys process the contrast dye, so we must ensure they are functioning optimally to clear it safely.
• Allergy Disclosure: Please inform the Scan4Health team if you have a known iodine allergy or have previously experienced a reaction to contrast media.
• Remove Metal Objects: You will be asked to remove watches, rings, bracelets, and any clothing with metal fasteners in the hand and wrist area, as metal can cause artifacts (streaks) that can obscure the fine details of the 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 Wrist at Scan4Health Gurgaon is a powerful tool used when clinical symptoms require detail that exceeds routine X-rays:

Key clinical uses include:

• Avascular Necrosis (AVN) Assessment: Contrast helps evaluate the blood supply to the small carpal bones such as the scaphoid. This is critical for detecting early-stage AVN, in which bone tissue begins to die due to reduced blood flow following an injury.
• Tumor and Ganglion Cyst Evaluation: Contrast is essential for characterizing masses or cysts in the soft tissues of the wrist, as it shows their vascularity and relationship to nearby nerves.
• Infection Detection: The scan is highly sensitive in identifying deep-seated infections such as tenosynovitis or osteomyelitis by highlighting inflammatory borders.
• Vascular Abnormality Mapping: It identifies arterial or venous abnormalities, such as narrowing or vascular malformations, that could be causing hand pain or numbness.
• Pre-Surgical Blueprinting: Provides a 3D blueprint for complex hand surgeries, helping surgeons navigate around the tiny bones and critical blood vessels.
