MRI

MRI (Magnetic Resonance Imaging)

Magnetic Resonance Imaging provides detailed images of internal organs, bone and soft tissues. The scanner uses harmless low energy radio waves and a strong magnetic field to produce detailed images. No radiation is involved.

Because a magnetic field is used it is necessary for the staff to know about any metal objects e.g. artificial joints, surgical clips, pacemakers, cochlear implants and aneurysm clips. Staff will ask you to complete a comprehensive questionnaire related to any metal objects that may be in your body. It also asks about the possibility of metal fragments within your eyes from working with metal, as these fragments may move during the scan because of the magnetic field. If metal fragments are a possibility you will be asked to have an x-ray prior to your MRI appointment to rule them out.

MRI scanning is ideal for imaging muscles, soft tissue organs and vessels. It is also ideal for demonstrating spinal and joint problems.

The scan is performed by a Medical Radiation Technologist (MRT) who has been specifically trained in MRI scanning. The images gathered are seen by a Consultant Radiologist with specialist training in interpreting MRI scans.

MRI scans generally take 20-45 minutes. You will be asked to lie completely still on a cushioned table and will be positioned within the scanner, depending upon the part of your body that is being scanned. The scanner will produce extremely loud knocking noises when it operates so you will be given either headphones or earplugs to wear. This is entirely normal.
