CT Scan

Computerised Tomography (CT) uses x-rays to take multiple pictures in very thin cross sectional slices through the part of the body that the doctor has asked to be examined. Using digital computer technology, these thin slices are then put together to reconstruct the examined body part in 3D. CT provides much more detailed images than plain x-rays. With all the slices and 3D reconstructions, the radiologist will make a diagnosis so that the right treatment will be planned.

Frequently Asked Questions

CT scans use a small amount of radiation exposure, but the benefits often outweigh the risks. The dose of radiation varies among different CT scans. We will consider your specific situation and ensure that the radiation dose is kept as low as reasonably achievable.

Some CT scans require fasting and/or drinking water. Our staff will give you instructions when you book your appointment either in person or over the phone.

Some CT scans require contrast dye, usually iodine-based. It is used to enhance the visibility of certain structures which enables our radiologist to provide an accurate diagnosis. Our radiologist will determine if contrast is needed based on your condition and the area being scanned. If needed, instruction and information will be provided to you at the time of booking.

The duration of a CT scan depends on the type of scan and the area being imaged. In general, a scan can take anywhere from a few minutes to half an hour.

During the procedure, you’ll lie on an examination table that moves through the CT machine. You’ll need to remain still, and you may be asked to hold your breath briefly during the scan.

CT scans are generally painless. Some people may experience a sensation of warmth when contrast dye is injected, but this is normal and temporary.

In most cases, you can resume your regular diet and activities after the scan. Your healthcare provider will provide specific instructions if any restrictions apply.
