COMPUTED TOMOGRAPHY

Is an appointment necessary?

Yes, appointments are necessary for this category of examination. Appointments can be made by calling the clinic where you intend to go for the examination.


What documents need I bring along?

Please bring along the letter or request form from a physician requesting for the particular examination.

Also, for easy identification, bring along your identity card or passport. This will also assist to expedite the registration process.

For follow-up cases, it is necessary to have previous x-ray films in order for the radiologist to compare and report on the progress of the condition.



How should I prepare for the examination?

No preparation is required except if the referring physician requires a contrast agent to be given intravenously. In this case, no food or drink is allowed for at least four hours before the appointment.

At the clinic, you may be asked to change into an x-ray gown and remove jewellery or ornaments which may obscure the region of interest.

For female patients, they will be asked to certify that they are not pregnant. If there is any possibility of pregnancy, this should be brought to the attention of the physician or radiographer or nurse attending to you.


How is the procedure performed?

The patient is positioned on the examination table. The radiographer will go to an adjacent room to initiate the x-ray exposure. There is a 2-way intercom between the examination and control room. A glass panel enables the radiographer to observe the patient at all times during the procedure.


Is the examination painful?

The CT examination is not painful. As in photograph taking, any movement during the procedure will render the image unclear. Patient may be instructed to stop breathing during the duration of the exposure which may last a few seconds.

A contrast agent may be injected into the patient. If this is done, you may feel a sting from the needle prick. Some people report a flushing feeling during the contrast agent injection but this will disappear within a minute or two. There is no cause for alarm.


How long will the procedure take?

The examination may take from 15 to 40 minutes.

After the procedure, patient will be asked to wait while the films are being processed and checked to be in order. This may take another 10 minutes.


When will the results be ready?

After the films have been processed, the radiologist will report on his/her findings. For urgent work, the results will be ready for collection in two hour's time at the clinic. For routine cases, the results will be despatched to the referring physician's clinic before your next appointment day.
