• Fasting Requirements: You must fast (abstain from solid foods and 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 permitted.
• Kidney Function Clearance (Serum Creatinine): Since 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. This ensures 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 reacted to contrast media in the past. Please also disclose if you have a history of asthma.
• Remove Metal Objects: You will be asked to remove jewelry, belts, and any clothing with metal zippers, buttons, or underwires from the torso area. Metal causes artifacts that can obscure the fine details of the spinal canal.
• 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 Dorso-Lumbar Spine at Scan4Health is a critical diagnostic tool utilized when clinical symptoms require a level of detail that exceeds routine X-rays:

Key clinical uses include:

• Tumor and Metastasis Characterization: Contrast enhancement is essential for identifying spinal tumors or metastatic disease spreading to the vertebrae. It helps show the tumor’s vascularity and its relationship to the spinal cord and nerve roots.
• Infection and Abscess Detection: The scan is highly sensitive in detecting spinal infections such as discitis or osteomyelitis, as well as epidural abscesses. These areas enhance under contrast, making them easier to pinpoint.
• Vascular Malformation Assessment: The contrast dye allows for the visualization of the blood supply to the lower spinal cord (conus medullaris). This is vital for identifying vascular abnormalities that can cause leg weakness or numbness.
• Inflammatory and Degenerative Mapping: It helps evaluate inflammatory conditions such as ankylosing spondylitis and can assist in differentiating between old scar tissue and new disc herniations in patients with prior spinal surgery.
• Complex Trauma Evaluation: In cases of severe back injury, the scan evaluates not just the bone fractures, but also any associated hematomas (blood collections) or active bleeding near the spinal nerves.
