3T Magnetic Resonance Imaging (MRI)
WHAT IS A MAGNETIC RESONANCE IMAGING (MRI) SCAN?
Magnetic resonance imaging, abbreviated as MRI, is a medical imaging procedure that uses a strong magnetic field and radio waves to create detailed images of the tissues and organs within the body. An MRI scan differs from a CT scan and an X-ray, as it does not use potentially harmful ionizing radiation.
GLENEAGLES PENANG’S 3T MRI SCANNER
Our Imaging Department is home to an advanced 1.5T Siemens Aera & 3T Siemens Skyra MRI scanner. With the latest 3T MRI scanner, we are able to overcome the challenges that come with abdominal MRI scan using FREEZEit technology which enables free-breathing examinations to those with limited breath hold capability.
HOW CAN I PREPARE FOR AN MRI EXAMINATION?
An MRI examination requires minimal preparation. Due to the strong magnetic field used during the examination, certain conditions may prevent you from having a MR procedure. Refer to your doctor about any of the following conditions that may apply to you:
- Claustrophobia – anxious or nervous about enclosed spaces.
- Medical devices – cochlear implants, aneurysm clips, pacemaker (non-MRI compatible), cardiac defibrillator, artificial heart valve, etc.
* For MRI compatible pacemaker – need to arrange pacemaker technician from the
implanted vendor to change the setting to MRI mode before perform MRI scan.
- Metallic implants and prosthesis.
- History of kidney problem.
- Skin tattoos.
- Allergy to iodine or gadolinium
WHAT CAN I EXPECT?
On examination day:
- Continue to take your daily medications unless instructed otherwise.
- No fasting is required unless you are scheduled for a Magnetic Resonance Cholangiopancreatography (MRCP). You will be required to fast for 6 hours prior to your appointment time.
- You should arrive at the Imaging Department least 30 minutes prior to your examination.
- You will be requested to change into a hospital gown and to remove any item that may contain metal to eliminate the possibility of safety issues and ensure image quality.
- You will be asked to complete the MRI screening checklist.
- If contrast is needed for the examination, an IV-line will be inserted in your arm by the nurse or consultant.
During the MRI scan:
- You will be placed on a moveable table that slides into the tube. A radiographer will monitor you from another room. A buzzer will be provided to you in the event you require assistance or wish to speak to the radiographer via the intercom.
- Earplugs or headphone will be provided to help reduce the noise from the scanner.
- Examinations vary in length and depend on what is being examined, but a typical examination lasts between 30 to 60 minutes per body part.
- During the scan, it is vital to stay still. Any movement during the scan will disrupt the images and the scan will have to be repeated.
- Depending on the body part that is being examined, you may be instructed to hold your breath for up to 20 seconds.
After the MRI scan:
- After the examination, you can return to your normal routine, either return to the doctor’s clinic or proceed with payment and go home.
- In some cases, after contrast injection, you may be asked to wait for a short time before leaving to ensure your wellbeing after the examination. Also, the IV line will be removed if no hospital admission is required.
- In the event that sedation is needed (such as for claustrophobia), you will be sent home once awake and alert. If you receive sedation, ensure someone else is driving you home.
HOW AND WHEN DO YOU GET THE RESULTS?
- MRI images are stored as electronic data files (PACS) and are usually reviewed on a computer screen. Your doctor will view the report through PACS once it is interpreted and approved by the radiologist.
- Your scan results will be reported within one (1) working day. However, urgent scans are reported within 4 hours.
- Reports and DVD copies of the MRI images will be provided upon request only. Please inform the Imaging receptionist (front desk) to prepare it in advance should you wish to collect it after consultation. Preparation of the DVD will take approximately 15 minutes.
