Magnetic resonance imaging (MRI) is an imaging technique that uses a powerful magnet and radiofrequency pulses to produce very detailed images of the inside of the body. The MRI scanner is a large tunnel which is open at both ends. It’s well lit and ventilated. The part of the body being scanned is placed in the centre of the scanner to obtain the images. A series of loud tapping noises are made as the machine acquires the scans. Unlike x-rays and CT scans, MRI does not use ionising radiation (x-rays). MRI is particularly useful for imaging of the brain, spine, abdominal and pelvic contents and other soft tissue structures of the body.
