To improve the experience of the MRI, it is advised that the patient not drink for several hours before the scan.Throughout the procedure, imaging technicians are able to communicate with the patient via intercom to ensure that the patient is informed and comfortable.The MRI scan is a painless and safe scan that produces clearer images of the body and its tissues, at any angle.Patients are often provided with earphones to listen to music to distract them from these noises during the procedure.The patient must remain motionless in order to produce a clear picture.If sedation is required due to claustrophobia, then there are associated risks of over-medication.If a contrast dye is used, which helps to show up some parts of the body more clearly, there is a small risk of allergic reaction.Other equipment that may cause a risk include cardiac pacemakers or defibrillators, a catheter with metal components, aneurysm clips, and cochlear implants.Some metal implants do not rule out using an MRI scanner, but some do, and it is important to tell a doctor about any implants or metallic objects.MRI stands for magnetic resonance imaging, a non-invasive diagnostic technique that uses radio waves rather than x-rays to create images.It is particularly useful for imaging of soft tissues such as the brain, spinal cord, muscles and ligaments and detecting abnormal tissues such as tumours.
