MRI scanners are particularly well suited to imaging non-bony body parts or soft tissuesThey differ from computed tomography (CT) in that they do not use the potentially harmful ionising radiation of x-rays. The brain, spinal cord, and nerves, as well as muscles, ligaments, and tendons, are much more clearly seen with MRI than with regular x-rays and CT; as a result, MRI is frequently used to image knee and shoulder injuries.

MRI can distinguish between white and grey matter in the brain and can also be used to diagnose aneurysms and tumours. Because MRI does not use x-rays or other radiation, it is the preferred imaging modality when frequent imaging is required for diagnosis or therapy, particularly in the brain. MRI, on the other hand, is more expensive than x-ray imaging or CT scanning.

One type of specialised MRI is functional magnetic resonance imaging (fMRI.) This is used to examine brain structures and determine which areas of the brain "activate" (consume more oxygen) during certain times of the day.. It is used to further our understanding of brain organisation and could provide a new standard for assessing neurological status and neurosurgical risk.

Are there any dangers?

Although MRI does not use ionising radiation like x-ray or CT imaging, it does employ a strong magnetic field. The magnetic field extends beyond the machine and exerts extremely powerful forces on objects made of iron, certain steels, and other magnetizable materials; it is powerful enough to fling a wheelchair across the room. Prior to having an MR scan, patients should notify their doctors if they have any type of medical or implant.
