Before the examination

  • Different examinations have specific preparation requirements. Please check with your doctor/ nurse if you are unsure.
  • If you have taken similar examinations in the past, it is advisable to bring them along on your appointment.
  • When making your appointment please inform the nurse if you are on medications for conditions like asthma, diabetes, cardiac or kidney diseases etc, or if you think you may be pregnant.
  • If you will be taking a mammogram examination, you may wish to be comfortably attired (e.g. wearing a button-on top) for ease of examination. Do not use powder or deodorant on your breasts or armpits on the day of your examination as it will affect the mammogram image.

During the examination

  • When your appointment is due, you will be led to the examination room by the radiographer.
  • You will then be requested to position yourself either on the examination bed or to remain standing when the examination is conducted. This will be explained clearly to you by the radiographer who will be conducting the examination. At no time should you be feeling uncomfortable and if you are, do inform the radiographer immediately.
  • Depending on the type and complexity of the examination, each examination will usually take between 10 - 35 minutes.

After the examination

  • The collection of results will depend on your doctor's request. The result will either be collected by you where you will bring it back to your doctor for further consultation or it will be despatched to your doctor who will then schedule an appointment to discuss the findings with you.
