Instructions for CT Patients

Types of CT Scans

CT scans are performed in two ways:

1. Non-contrast CT – No fasting required.
2. Contrast-Enhanced CT – Requires fasting for approximately 3-6 hours before the scan.

Contrast Administration Methods

Contrast can be administered through:

• Intravenous (IV) Injection
• Oral solution (to be consumed)
• Rectal contrast (in some cases)
• More than one method may be used if required.

Precautions for Certain Patients

• Patients with borderline or high kidney function test (KFT) values (urea/creatinine) may need alternative contrast or may avoid contrast altogether.
• Elderly, diabetic, hypertensive, or kidney disorder patients should bring their latest urea/creatinine reports before undergoing a contrast-enhanced CT scan.

Possible Side Effects of Contrast

• Before contrast is administered, a small test dose is injected to check for reactions.
• Oral contrast may cause nausea and vomiting.
• IV contrast may cause:
• A temporary warm sensation or slight uneasiness.
• Mild to moderate allergic reactions (rash, itching, or other symptoms).
• Inform the technician if you experience persistent discomfort.

Procedure Details

• CT Abdomen Contrast: Given orally, intravenously, or rectally.
• Scan Duration: Depends on the study type, but most scans take only a few minutes.
• During scanning, you may hear machine noises – this is normal.
• Our technician/doctor monitors the scan for safety and quality.
• Emergency Cases: Patients with prior appointments may have to wait in case of medical emergencies.

Patient Instructions

• Do not move during the scan – you may be asked to hold your breath for a few seconds.
• The scan may be extended to capture delayed images if required.
• A two-way speaker system allows communication with the technician for patient comfort.
• Turn off mobile phones before entering the CT room.
• The center is not responsible for loss or damage of valuables (cash, jewelry, mobile phones, etc.).
• Pregnant women or those who suspect pregnancy should inform the physician before the scan.
