Magnetic Resonance Imaging (MRI)
MRI (Magnetic Resonance Imaging) is the name given to a technique, which builds up pictures of an internal cross-section of the part of the body under investigation.
It uses a magnetic field and radio waves, together with an advanced computer system. It builds up a series of images, each one showing a thin slice of the area needing examined.
These images are very detailed. They can show both bones and soft tissues in the body and provide a great deal of information. Using the computer, the 'slices' can be also be obtained in any direction.
To generate the MRI images the patient is required to lie on a table and enter a tunnel within the machine for 15-60 minutes depending on the body part being examined. Some patients who are claustrophobic may find this difficult. However our experienced Radiographers are well used to this and will speak to you throughout and put you at ease.You may also arrange a visit to see the scanner prior to your examination.
MR images allow doctors to evaluate parts of the body and certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound, or CT scanning.
This exam does not use ionising radiation however may require an injection of a contrast material (x-ray dye) to enhance the images for the reporting Radiologist.
The magnetic field is not harmful, but it may cause some medical devices to malfunction. Most orthopedic implants pose no risk, but you should always tell the Radiographer if you have any medical devices (pacemakers, aneurysm clips etc.) or metal in your body.
You will be asked to fill in a detailed patient questionnaire when you attend for your examination and the examination will be explained in detail and any questions answered thoroughly.
MRI Examinations performed and reported by Nelson Radiology use some of the most advanced MR equipment currently available.
As well as general MRI examinations brain, spine, abdomen, pelvis etc., areas of expertise include:
- Whole Body MRI screening
- Musculoskeletal MRI (in particular sports injuries)
- Hepatobiliary Imaging (MRCP)
- Cardiac MRI
At the time of examination the Radiographer will not be able to give you any results. A Consultant Radiologist will report on the images and provide a report to the clinician who referred you within 72 hours.
Depending on the scan you will take a CD of the images home with you on the day.
