CT Scan

Overview:

A CT scan is a test that uses a series of x-rays to create images of the bones and soft tissues in the body. The images can be viewed from different angles and provide a more detailed information when compared with plain x-rays.

When it’s done:

The test is performed to:

• Diagnose muscle and bone disorders including bone fractures and tumours
• Identify the site of a tumour, infection or any blood clots
• Guide procedures such as surgery, biopsy and radiation therapy
• Diagnose diseases such as cancer, heart disease and lung or liver disorders
• Identify internal injuries and internal bleeding

When to Avoid:

• Inform your doctor if you have had allergy to contrast dyes
• Avoid the test if you are pregnant
• Inform your doctor if you are on metformin (Glucophage) for diabetes

How to prepare:

It depends on which part of the body is being scanned. You may be asked to:

• Remove any jewellery that you are wearing because it may interfere with the test results
• Do not eat anything for 4 to 6 hours before the test
• In case of infants or toddlers, the doctor may inject a sedative to keep the child calm and still because movements may result in blurred images
