The CT Scan may be of the head or a selected part of the body. This special X-ray gives a picture of your body in a cross section, giving more detail than other X-rays through the use of a computer.
The scan will be done with you lying on a special table that moves slowly into a donut-shaped scanner. You may be asked to hold your breath for short periods of time. You will hear whirring noises as the gears and motors work during the procedure. The staff will be in an adjoining room and can talk to you. They will have full view of you through a window. You will be able to continue your normal activities after your exam.
Do not wear metal objects such as hairpins or earrings. You may be given a contrast media injection through your vein to highlight or enhance the brain tissue. If you have any allergies, please tell the staff. You may eat and drink as normal. It would be helpful to wear loose fitting clothes without snaps, buckles, or other metal objects.
