Service Availability

For service outside business hours, the requesting doctor is required to ring the on-call radiologist, who can be located via switchboard. If the scan is deemed necessary, the radiologist will contact the radiographer on call. When the CT staff arrive in the hospital, they will then ring the requesting department to bring the patient to the department.

There is open access to the CT service provided the patient has a current referral from a medical practitioner either from within or outside the hospital.Image of CT Waiting Room - Click to Enlarge

In general, there is no waiting time for CT scans unless a general anaesthetic (GA) is required. There are three GA sessions allocated to CT each fortnight, into which non-urgent scans are booked. All urgent scans are done the day they are requested.

Patient Preperation

In general, no preparation is required for CT scans. However, if the patient requires oral contrast for an abdominal or pelvic scan, a 3 hour fast is recommended. A drink containing a special x-ray contrast will be given to the patient to have before the scan. The quantity and timing of this is related to the age of the patient and what area is being scanned.

It is also preferable for patient’s requiring intravenous contrast to be fasted for three hours prior to their scan. In emergency situations, this is not necessary.

If the patient requires a GA separate fasting instructions need to be adhered to. If the GA is booked well before the scan, the pre-anaesthetic nurse will ring the parents to inform them of what is required, and when the patient needs to be in the hospital.

Consent Forms

All patients undergoing a CT scan examination will need to have at least one consent form completed.

There are two separate consent forms that may be required. The first is consent for the actual scan itself. It talks about the radiation risk involved as well as giving a general explanation of the procedure.

The second form is consent for the use of intravenous contrast. Many of the scans performed in CT require the use of an intravenous contrast medium, which is used to delineate structures, thereby giving more information to the reporting radiologist. As with any drug, patients can experience an allergic reaction. The form lists the associated risks with use of the contrast and asks a number of questions regarding the patient’s medical history, in order that a reaction can be avoided.

Patients with poor kidney function, or on certain medication (eg Metformin) will not generally be given the contrast, so it is very important that this information is conveyed to the radiologist.

It is necessary to have a parent or legal guardian present when the child comes for the CT scan, so that this written consent can be obtained. If it is not possible for the parent to be present, consent should be obtained by the requesting doctor prior to the patient presenting in the Diagnostic Imaging Department.

If you require a copy of either consent form, please click the links below.
