MRI
Magnetic Resonance Imaging (MRI) uses a powerful magnet and radiofrequency to obtain extremely detailed cross sectional images of the body.
Signals are detected by a receiving device (called a coil) that is placed around the body part being scanned.The signals are then processed by powerful computers to form a detailed image.
A typical MRI examination can take from 10 minutes to an hour, and does not cause any discomfort. Sometimes an injection of contrast medium (dye) may be required to assist with diagnosis.
MRI is particularly good at providing detailed images of soft tissue and joints.
MRI machines can be quite loud. We provide all our patients with headphones so they can listen to music of their choice and to also help cancel out noise. In preparation for scans, patients are required to remove all jewellery and metallic objects and also answer a short safety questionnaire.
For Patients with Implanted Devices
If you have an implanted device, such as a pacemaker, defibrillator, neurostimulator, cochlear implant, or any other metallic or electronic implant, please be aware that MRI may not be suitable for you.
Because MRI uses a powerful magnetic field, the presence of certain implanted devices can pose a safety risk. Before your scan can be booked, we are required to research and verify whether your specific device is compatible with MRI. This process involves reviewing your implant documentation, consulting manufacturer safety data, and in some cases liaising with your treating specialist.
Please note that this assessment process takes time, and we are unable to guarantee that an MRI appointment can be offered with short turn around times. In some cases, your device may be deemed incompatible and an MRI will not be possible.
If you have an implanted device and have been referred for an MRI, please contact our team as early as possible so we can begin the eligibility assessment.
