Magnetic Resonance Imaging (MRI)
is a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is frequently employed in the detection, diagnosis, and monitoring of diseases. It works by stimulating and detecting changes in the rotational axis of protons contained in the water that makes up biological tissues.
How does MRI work?
What is MRI used for?
MRI scanners are especially well adapted to imaging non-bony bodily components and soft tissues. They differ from computed tomography (CT) in that they do not employ x-rays, which emit harmful ionising radiation. MRI images the brain, spinal cord, and nerves, as well as muscles, ligaments, and tendons, considerably more clearly than normal x-rays and CT; as a result, MRI is frequently used to imaging knee and shoulder problems.
MRI can distinguish between white and grey matter in the brain and can also be used to diagnose aneurysms and malignancies. MRI is the imaging modality of choice when frequent imaging is necessary for diagnosis or therapy, especially in the brain, because it does not use x-rays or other radiation. However, MRI is more expensive than x-ray imaging or CT scanning.
Functional Magnetic Resonance Imaging is one type of specialised MRI (fMRI.) During various cognitive tasks, this is utilised to study brain architecture and determine which parts of the brain “active” (consuming more oxygen). It’s used to further our understanding of brain organisation and could be a new benchmark for determining neurological status and neurosurgical risk.
