MAGNETIC RESONANCE IMAGING (MRI)

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.

If you have downloaded the MRI questionnaire, please bring it along the completed form. This will save you some time at the clinic.



How should I prepare for the examination?

No preparation is required. Avoid makeup and mascara as they often contain metallic elements.

Patients for abdomen studies and cardiac studies are required to fast for at least four hours.

Patients who require sedation will also need to fast for four hours.

At the clinic, you may be asked to change into an x-ray gown and to remove jewellery or ornaments, magnetic cards, analog watches and keys.

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.

Patients and children who tend to be claustrophobic may be given a sedation to help the patient through the procedure. If this is the case, an accompanying adult need accompany the patient. An informed consent for the sedation will be required.


How is the procedure performed?

The patient will lie on the examination table. If it is a head examination, a 'open' helmet will be placed on the patient. The patient will then be moved to the centre of the scanner. The radiographer will be at the control room and there is a 2-way intercom to facilitate communication. The patient can communicate with the radiographer and vice visa if necessary.


Is the examination painful?

The MRI examination is not painful. But as in photograph taking, any movement during the procedure will render the image unclear. Patient will be comfortably lying on a padded mattress and must keep still during the scan.

During scanning, intermittent humming and drumming sounds will be heard. Earplugs will be provided.


How long will the procedure take?

The examination may take from 30 minutes to one hour.

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 the next appointment date.
