What is MRI scan?

MRI uses a magnetic field and radio waves to take pictures of a part of your body with computer-generated, cross-sectional images of all the organs and tissues scanned. It occasionally requires intravenous injection of contrast medium into a vein, usually at your elbow or back of the hand.

What do we need to know at the time of booking and before the examination?

  • If you have any metal implants of any kind, such as heart pacemaker, neurostimulator, metal pins, medication pump, or/and joint replacements.
  • If you have worked with metal.
  • If you have poor renal function.
  • If you are claustrophobic.
  • If you have had any reaction to a contrast injection given for a previous MRI scan.
  • We will need you complete a questionnaire before the examination, and sign a consent form to the contrast injection if it is required for your examination.

Preparation:

Please bring any previous films with you for comparison.

Head, Spine, Bones and Joints:

No preparation required.

Abdomen and Pelvis (including Rectum):

Fast 4 hours and rectal cleansing either prior to or an hour before study.

What happens?

You will be asked to remove all metal objects, including wristwatches, keys and jewellery. These items must be left outside the scan room.

  • You may need to change into a gown. You can wear comfortable soft clothing without any metal zippers or clips.
  • You then lie on the scanner’s table which slides into the scanning cylinder until the body part to be examined is in the centre of the scanner.
  • A planning scan is then done followed by up to six different scans to show different features of the body part examined. Each of these scans will take 30 seconds to 4 minutes to acquire, depending on the exact sequence.
  • If contrast is required it is given just before the last 2 or 3 scans.
  • You need to keep perfectly still with gentle breathing during each of the individual scans, otherwise you will get suboptimal images which may not be readable.
  • You may have to hold your breath for up to 30 seconds if scans are being done of your chest or abdomen.
  • The scanned area of your body may feel a little warm.

How long does an MRI scan take?

About 20-45 minutes in total depending on the nature of the investigation.

Special precautions:

Allergic reactions to contrast material can occur but significant reactions are rare, and generally respond to adrenalin. Our staff members are equipped and trained to treat contrast reactions. Some scans create a slight sensation of heating. There are no adverse effects from the magnetic field or radio waves used to generate the images.

After your examination:

There are no known side effects from undergoing MRI. The MRI scan is a non-invasive, painless and safe procedure that doesn’t require any ‘recovery time’. There are no special after-care instructions.

What are the risks of MRI scan?

The MRI scan is a very safe procedure. Occasional complications may include:

  • Metal objects (such as jewellery) worn during the scan can cause injury.
  • The powerful magnetic field of the MRI scanner may damage internal metal devices, such as a heart pacemaker.
  • In some cases, such as in the investigation of blood vessels, a contrast dye is injected into a vein immediately prior to the scan. This helps to produce a clearer picture. Rarely, a patient may have an allergic reaction to the contrast dye.

Your images and report:

It is important that you make an appointment to return to your doctor after you have collected your examination result. Whether they are normal or abnormal, your doctor needs to correlate with other information for further management.

Your result will include a copy of the images from your study as well as a report from our radiologist.

Depending on your referrer’s preference(s), a copy of the report can also be sent to your referring doctor by fax or electronic download.

Digital copies of all studies are stored on our secured database for comparison with any future examinations.

Special instructions for diabetics:

If your examination requires fasting, then book an early morning appointment and have your breakfast and diabetic medication after the examination.

If your examination will require an intravenous injection of contrast medium, we need to know your renal function. Please bring along the results of your most recent blood test with your creatinine and GFR level.
