• Fasting Guidelines: You are required to fast (abstain from all solid foods and colored beverages) for at least 4 to 6 hours before your scan. This is a standard safety precaution for the administration of intravenous contrast. You may continue to drink plain water to stay hydrated.
• 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. This confirms that your renal function is optimal for the safe clearance of the dye.
• 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. We also need to know if you have a history of asthma, as this can slightly increase the risk of a mild reaction.
• Clothing and Jewelry: Wear loose, comfortable clothing. You will be asked to remove all metallic items from the chest area, including necklaces, bras with underwires, and clothing with metal zippers or buttons, as metal causes artifacts that can obscure vital lung details.
• 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 scan.
• Breath-Holding Practice: During the scan, you will be asked to hold your breath for a few seconds. This prevents motion blur and ensures the sharpest possible images of the lungs and heart.
• Post-Scan Hydration: Plan to drink plenty of water (8–10 glasses) for 24 hours after the test to help your kidneys flush the contrast agent from your system.

The CE CT Chest at Scan4Health is a cornerstone of modern thoracic medicine, offering superior diagnostic capabilities across several key areas:

Key clinical uses include:

• Oncology and Tumor Mapping: Contrast enhancement is critical for identifying lung nodules and determining if they are highly vascular (a sign of potential malignancy). It also helps visualize lymph node enlargement (lymphadenopathy) in the hila and mediastinum, which is vital for cancer staging.
• Vascular Assessment: The scan provides a clear view of the aorta, pulmonary arteries, and superior vena cava. It is the gold standard for diagnosing a pulmonary embolism (PE), aortic aneurysms, or dissections.
• Infection and Abscess Localization: In cases of severe pneumonia or suspected lung abscesses, contrast helps distinguish solid tissue consolidation from fluid-filled cavities, allowing for more targeted antibiotic therapy or drainage.
• Mediastinal Evaluation: The scan helps evaluate the thymus gland, esophagus, and heart borders. It is particularly useful for investigating mediastinal masses that are often hidden behind the breastbone on standard X-rays.
• Pleural Disease Management: The CE CT allows for the detailed visualization of the pleura (the lining of the lungs). It can detect pleural thickening, tumors (such as mesothelioma), or localized pockets of fluid (pleural effusions).
