.: computed tomography (ct scan)

A CT scan is a series of images obtained using x-rays to assess the structures and anatomy of any part of the body.

Please contact us immediately on 06 753 7873 if:

  • You have been given an outpatient appointment with the consultant who referred you to CT within 2 days of this appointment. Otherwise, the scan results may not be ready in time for your clinic appointment.
  • You are pregnant.

Before arriving at your appointment:

  • Please continue to take any medication.
  • Please read the appointment letter for any special preparation instructions.
  • You may need to wear a hospital gown for your examination so please wear clothing that can be changed easily.
  • Metal objects including jewellery or body piercings over the area being examined may affect the CT images and should be left at home or removed prior to your examination.
  • Generally examinations run to a tight schedule, so please be on time.  Though we do not anticipate any delays in your examination, please consider bringing a book, magazine, or music player to help you pass the time while you are waiting as we do have to accommodate emergencies as they arise. 

After Arriving:

  • Please report to Radiology Reception on arrival.
  • The Receptionist will check your details for accuracy and you will be directed to the waiting area.
  • A radiology nurse or radiographer will collect you from the waiting area, check your details and ask you a few questions regarding your medical history.
  • You may be asked to change into a gown and/or remove items like jewellery or body piercings etc. 

During your examination:

  • While positioning you on the CT examination table, the radiographer will explain your procedure and answer any questions you may have.
  • You will be asked to lie still on the CT examination table.  In some cases, pillows or straps may be used to help you maintain the correct position and to hold still during the examination.
  • When you enter the scanner, laser lights are used to ensure that you are properly positioned.
  • The examination table you are on will slide into the scanner, only covering the part of your body which is being studied.  The scanner is open at the back and the front, allowing you to ‘see out’.
  • You will be alone in the examination room during the actual scan, however the radiographer will always be able to see, hear and speak to you. The time it takes to actually acquire images is very brief.
  • With paediatric patients, a parent may be allowed in the room but will be required to wear a lead apron to prevent radiation exposure.
  • You will hear only slight buzzing, clicking and whirring sounds as the CT scanner takes images.
  • The images will be reviewed, and if necessary, some may be repeated or additional scans performed.
  • This procedure usually takes approximately 15-30 minutes. 

After your examination:

  • A Radiologist will examine your images and write a report of the findings. This report will be sent to the Specialist who referred you for the CT. A copy will usually also be sent to your GP.
  • Some scans need further computer processing and take longer to analyze but results will be sent within 3 to 5 working days and sometimes sooner.
  • We are unable to give you any information related to your results but your doctor will share the results of your examination with you.
