.Procedure Information

Computed Tomography (CT) is a fast, non-invasive diagnostic tool that uses x-rays to take detailed, multi-slice images of the body. A CT scan is commonly used to assess a body part's structure or shape, diagnose disease, trauma, injury or vascular disease and aid surgery, radiotherapy or diagnostic procedures. A CT Coronary Angiogram (Cardiac) is a procedure that uses X-rays and computerised analysis to produce cross-sectional and three-dimensional images of the blood flow in coronary artery. The Cross Radiology possesses one of the latest, most highly-efficient and ultra low radiation dose CT scanners on the market- the Toshiba Prime 160. This scanner leverages on Toshiba's recent innovations to deliver a wide bore gantry, better patient comfort through faster acquisition times and superior image quality.

Preparation/What to Bring

An appointment is necessary for a CT Cardiac as there is preparation involved and you may be required to attend for over an hour. Bring with you your doctor's request form, your Medicare and/or pension health care card, along with any previous studies.

During the appointment process, you may be asked to attend our practice a day or two before your allocated time for a pre-assessment. This is to assess your blood pressure and heart rate.

IV Contrast will be administered during the study. For detailed information on IV contrast, please click here.

During the Examination

Before the procedure, you will be given an information sheet along with a consent form. You will be asked to fill in a questionnaire highlighting your medical history and to give an informed written consent. It is important to tell us if you are pregnant, diabetic, allergic to contrast, suffer from kidney disease, asthmatic or taking any medication. Before the procedure begins, you will be given a medication called a beta-blocker to slow your heart rate (this may be given to you during the pre-assessment to take at home prior to arrival). This is necessary because the CT angiography examination is timed to your heart rhythm, and lowering your heart rate will improve the CT images. You will be asked to change into a disposable gown and will then be positioned for the scanning process on the CT table on your back. The radiographer will attach ECG leads to your chest to monitor your heart rate. A small cannula will be inserted into your arm for the contrast. When the contrast is being administered, you may feel a warm flush throughout your body, along with a metallic taste in your mouth. This will pass quickly. It is important you do not move while the images are being acquired. The CT table you are on will move in and out of the scanner.

The scanning process should take between 10-20 minutes, however you may be attending the practice for over an hour depending on your heart rate.

After the Examination

There are no special instructions after a general CT scan. You may continue your regular activities as normal.

After your examination, the most pertinent images from your study will be printed. Along with these images, a written report will be produced by the Radiologist. These results are generally delivered to your referring doctor via our courier, fax and/or email. It is important you return to your doctor to discuss the findings. The Cross Radiology stores electronic copies of all examinations in a secure database, and can be accessed at any time for future studies.
