At South Coast Radiology we have the latest generation of multi-slice CT scanners, which allow for high detail imaging in 3D.

  • WHAT IS COMPUTED TOMOGRAPHY (CT)

    Computed Tomography (CT) is a non-invasive exam that helps diagnose and treat a vast array of medical conditions. CT combines X-rays and sophisticated technology to take detailed cross-sectional pictures of the body, similar to pages in a book.

    At South Coast Radiology we have the latest generation of multi-slice CT scanners, which allow for high detail imaging in 3D. CT scans of organs, bones, soft tissue and blood vessels provide improved clarity and information as part of a multi disciplinary approach.

    CT scans are painless and straightforward. Examination time varies from 5 to 15 minutes depending on your study. Recent advancements now enable multi-slice CT scanners to obtain multiple cross-sectional slices during a single rotation.

    All South Coast Radiology radiographers have the necessary qualifications and experience to ensure the best patient care and high-quality X-rays. All our radiographers are accredited and licensed by Queensland Health and the Australian Institute of Radiography.

  • BEFORE A CT SCAN

    Patients over the age of 70 or diabetic patients may be asked to undergo a blood test prior to a CT scan to measure kidney function. Our booking agents can arrange this if no recent results are available.

    Our staff will inform you of any preparation instructions required with your specific examination. Some tests require no preparation, however many types of CT require an injection of contrast media (or dye) to show detailed vessels and organs of the areas of interest. For these tests you will be required to fast prior to your appointment, these instructions will be provided to you in detail at the time of booking.

    If you do require contrast our radiographer or radiologist will discuss this with you. The contrast is inserted via a cannula in your arm or hand.

  • DURING A CT SCAN

    You may be asked to remove any metal that is in the scan area including jewellery, zippers and bras, and you will be asked to lie on the examination table. If you require an injection of contrast media, it will be administered at this point via the radiographer or a machine pump.

    When the contrast is administered, patients often get a metallic taste in their mouth and feel a hot flushing warm sensation throughout the body. This warm sensation can concentrate around the groin and buttock region giving the feeling of emptying your bladder. Do not be concerned as these sensations are not an allergic reaction and will pass within a couple of minutes.

    The radiographer or machine may give you breathing instructions, such as direct you to hold your breath briefly.

  • AFTER A CT SCAN

    Once the radiographer has reviewed the scans to ensure all appropriate images were captured, your cannula will be removed and you will be taken to a waiting bay for 10-15 minutes after your scan for staff to monitor you for signs of allergic reaction.

    The reconstructed  images will be interpreted by our radiologist, who will produce a comprehensive report. Previous imaging will be compared if available to the Radiologist. The results of your scan will be sent directly to your referring Doctor, and it is very important you book a timely follow-up appointment to discuss your results.

  • PATIENT SAFETY

    As CT uses X-rays to recreate the pictures, our staff are highly trained to use the lowest radiation dose possible for high quality images, minimalizing radiation exposure and decreasing risks involved. The radiographer will only scan the area/s of concern, avoiding unnecessary exposure. The benefits of an X-ray generally out outweigh the risks involved.

    Pregnant patients should avoid having a CT scan, in order to avoid exposing the fetus to unnecessary radiation.

    There are very limited contra indications for CT, meaning almost anyone is eligible to have a CT scan. However, like anything that you introduce to the body there is a risk of allergy involved. Although rare there are some people that might be allergic to the contrast media.

    The results of your scan will be sent directly to your referring Doctor, and it is very important you book a timely follow-up appointment to discuss your results.

CT Angiography

CT Angiography is a type of CT scan that examines the arteries around the body. It requires an injection of CT Contrast (please refer to ‘During a CT Scan’ for further information). Some of the reasons for having a CT angiography include but are not limited to:

  • Aneurysm
  • Blocked vessels
  • Follow up from other imaging as recommended by Radiologist for example – Ultrasound
  • Arterial Stenosis
  • Poor blood flow

Cardiac CT

CT Coronary Angiogram is designed to examine the very small arteries that supply blood to the tissue of the heart. CT Coronary Angiogram requires CT Contrast (please refer to ‘during a CT Scan’ for further information).

Due to the constant movement of the heart we need your HR to be as low and as steady as possible for us to be able to image it motion free. Due to this you will be asked to stop your intake of Caffeine 24hrs prior to your test. Coffee, tea and chocolate should be eliminated for 24 hours prior to your examination.

You will also be asked to arrive approximately 1 hour before your scan for our nursing staff to assess your heart rate and administer medication to slow it down if necessary.

Cardiac CT is only performed at SCR John FlynnPindaraDarling Downs Radiology and Mackay Radiology.

*Cardiac CT is bulk billed with a specialist referral.
