what to expect from your CT scan

CT

What is CT?

CT stands for Computed Tomography, an imaging technique used to visualise both the soft tissue and bone inside your body.

How does CT work?

CT uses special x-rays to obtain image data from different angles around the body. A powerful computer is then used to process the information to show a cross-section of body tissues and organs - much like viewing the slices of a loaf of bread.

What is CT used for?

CT imaging can show bones, as well as surrounding tissues such as muscle and blood vessels with great clarity. Using this technique, Radiologists can more easily diagnose problems such as cancer, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.

What do I need to do before my CT scan?

It is important that you closely follow any instructions that you are given about eating, drinking or taking prescribed medication prior to you scan. If these instructions are not clear, please telephone the contact number on your covering letter.

Most people can have a CT scan, however as the procedure uses x-rays, we will not scan pregnant women. Please tell us if you are pregnant or if there is a possibility that you could be expecting.

Some types of CT scans use a form of ‘contrast’. This is a drink or injection that allows the doctor to see your condition more clearly. You will be asked about allergies, but these contrast agents are very safe and do not have any after-effects.

What will happen during your scan?

For your scan, you will lay down on a comfortable scanning bed that will slowly move through a doughnut shaped ring called a gantry. You will experience no discomfort or pain, but may hear some soft mechanical noise from the scanner.

Scan times are very short (between 10-20 minutes) and the technologist operating the scanner can both see and hear you throughout the procedure, so if you have any concerns you only have to say. CT scans are comfortable and quick but during your scan will need to lay still and may be asked to hold your breath for brief periods

What can you expect after you scan?

The results of you scan will be analysed by a Radiologist who will provide your doctor with a comprehensive report. Your doctor will then discuss the findings of the report with you and plan any treatment or next steps.
