Information for Patients 

Computed tomography, also referred to as CAT scan, uses specialized x-ray equipment to obtain images of the body. The CT scanner emits and records x-ray beams and uses specialised computer software to form cross-sectional images, or slices of the area scanned. CT scans are used in the diagnosis and assessment of head injuries, stroke, clots in the lungs, abdominal pain and for cancer management.

Some types of CT scan will involve an injection of intravenous contrast (or dye) into a cannula (or line) arm in your arm. It is important for us to know your kidney function prior to administering intravenous contrast and we may need a copy of recent kidney function tests. Certain CT scans may also require you to drink contrast liquid before the examination.


Most CT appointments can be facilitated with 5 days of referral. Urgent requests can be performed on the same day. A referral letter from your doctor is required when the scan is booked. To make an appointment please see our contact section.


Types of CT Scans & Patient Preparation


CT Brain / Neck / Sinuses 

This test is used to assess the brain for various conditions such as suspected strokes or head injuries. A CT sinus performs images of the paranasal sinuses to look for congestion or blockages. Patient preparation is not required prior to these examinations. The majority of CT brains do not require intravenous contrast.

CT Thorax / High Resolution CT (HRCT)

A CT scan of the thorax is used to assess a wide range of lung conditions including suspected clots, tumours and pulmonary fibrosis. Lung cancer screening is performed in conjunction with our Respiratory Physicians and follows international guidelines. Certain CT thorax require intravenous contrast however no other patient preparation is required.

CT Cardiac / Calcium Scoring 

Cardiac CT scanning is a non-invasive test to assess the coronary arteries. It is an alternative to a coronary angiogram and is performed in conjunction with our Cardiologists. Patients need to be admitted to the day ward and a Consultant referral is required. Calcium scoring is a CT test to measure the level of calcium in your coronary arteries which can given an indication of your risk of underlying blockages. No patient preparation is required and this test can be ordered by your GP.

CT Abdomen and Pelvis

This type of CT scan is used to assess the abdominal and pelvic organs for a variety of conditions including abdominal pain, weight loss and tumour staging. In general, intravenous and oral contrast is required and patients must fast for 6 hours prior to the CT study.

CT Colonography

The American Cancer Society (ACS) recommends that women and men undergo screening for colon cancer or polyps beginning at age 50. CT colonoscopy is a well recognised alternative to conventional colonoscopy for patients who cannot tolerate the more invasive procedure or where the entire colon cannot be visualised. The test requires a tube to be placed into the rectum which is used to inflate the colon with air. CT images are then acquired. Patient preparation is required which will be detailed by our staff.

Vascular CT / CT Angiograms

Vascular CT is a non-invasive test to assess the blood vessels. Intravenous contrast is administered and CT images are then obtained. This type of CT is used to investigate vascular blockages and aneurysms. No patient preparation is required.

Extremity / Bone CT

CT gives excellent images of the bones and is commonly performed to plan orthopaedic surgery or when MRI of joints cannot be done. No patient preparation is required.
