What is a CT scan?
A CT (Computed Tomography) scan uses X-rays from multiple angles to capture images of the body.
These images are reconstructed by a computer to create cross-sectional views of the inside of the body.
This method is useful for detecting abnormalities and diseases in various organs.
CT Scan Procedure
- The test usually takes 5 to 15 minutes. You will need to lie still and stay relaxed inside the machine.
- A contrast agent may be used if needed for better results.
- If contrast is used, do not eat or drink for at least 6 hours before the test.

What to Know Before Using Contrast Material
If you have allergies, asthma, heart disease, past drug reactions, other medical conditions, or take diabetes medication , please tell your healthcare provider before the test. These conditions can increase the chance of side effects .

To stay safe, do not take these medicines for at least 48 hours after the test . -
