Computed Tomography

Computed Tomography

A CT scan is an x-ray procedure that is enhanced by a computer and gives out a three-dimensional view (referred to as a slice) of a particular part of the body. It is a highly sensitive method to accurately view the internal anatomy and detect extremely small lesions.

What Is It?

CT stands for computerised tomography. CT is a diagnostic imaging technique that produces a sequence of detailed cross-sectional images of the body.

What You Must Tell Us?

If you have had an adverse reaction to a previous contrast injection or other drugs or if you have any renal impairment.If you take any diabetic medication that contains metformin (examples of which are diabex, diaformin, avandament, glucomet, novamet, genex, glucophage), insulin, or blood thinner (warfrin or aspirin products).If you are pregnant or suspect you may be pregnant or breast feeding.

How To Prepare?

You should arrive 15 minutes before your appointment time to complete all necessary paperwork.

You should wear comfortable clothing that have no metal zippers, belts or buttons in the abdominal or pelvic areas. You may be asked to remove jewellery, eyeglasses and metal objects that could interfere with the x-ray images. If you do not have clothing without metal components we may ask you to change into a gown.Medications may be taken as prescribed.

You may be asked to stop eating solid foods 2 hours prior to the procedure.

Depending upon which part of the body is being scanned you may be required to drink an oral contrast 1 hour prior to your exam. If you are having scans of your abdomen and/or pelvis you will need to drink this. The contrast helps to outline the stomach and intestines so abnormalities can be identified.

Bring any previous x-ray and CT films with you to the appointment in case they are needed for comparison.

What Does The Procedure Involve?

You will be taken into our procedure room and positioned on a CT table either head first or feet first, depending on the part of the body being scanned. Some CT scans require Intravenous (IV) injection of contrast medium into a vein, usually at your elbow or back of the hand. It helps to visualize veins and arteries and certain tissues, as well as your urinary tract.
