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 20 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.
