Magnetic Resonance Imaging (MRI) uses powerful magnetic fields and radiofrequency pulses with the help of a computer to produce high resolution and detailed diagnostic images of internal human organs and structures. MRI is very safe, painless and has no known health risks. It is a valuable tool for the diagnosis of diseases and conditions of the brain, spine, heart and blood vessels, breasts, bones, joints and other internal organs. MRI may give more detailed information than an X-Ray, Ultrasound or CT scan.
How do I prepare for an MRI
MRI uses magnetic waves and you will be required to remove all metallic objects and accessories you may be wearing prior to the procedure. These include items such as hairpins, jewelry, eyeglasses, belts, hearing aids, wigs, underwire bras, etc.
Through our MRI screening process, you/your guardian will be required to notify the MRI Technologist if you have:-
- Any history of surgeries.
- Any implanted devices or limbs like hip, knee and spine.
- Artificial heart valves or a cardiac pacemaker.
- Any metal plates, pins or screws.
- Tattoos or permanent make up.
- Bullet or shrapnel in your body.
- If you are pregnant or suspect you might be pregnant.
What to expect during an MRI procedure
On average, an MRI procedure takes between 15-40 minutes although some procedures may take longer. Before the MRI procedure, you may be asked to change into a hospital gown for your safety and to ensure that your clothing does not affect the quality of the scan. A locker will be provided to secure your belongings. Once you have changed into a hospital gown, you will lie down on a movable table (gantry) that slides into the opening of the MRI tube.
The Technologist will sit in an adjacent room and monitor you throughout the procedure. You will be provided with a buzzer to get the Technologist’s attention at any time. You will be required to stay still throughout the procedure. You will hear loud tapping or thumping during the procedure but at VitalRay Health Solutions, you will be given noise-cancelling headphones to alleviate this.
In some cases, a contrast material may be administered through an intravenous (IV) line. The contrast enhances the appearance of certain details in the images. Once the procedure is complete, you may resume your usual activities immediately. A Radiologist will analyze the MRI images and produce a Report that you can discuss with your doctor.
