MRI is very safe. Prior to MRI, there is no need for fasting unless instructed to do so. When we go for an MRI scan, we need to remove metals from our body, such as jewelleries and metal spectacles. It is also important that we inform the radiographers if we have metal implants in our body. The radiographers will then position us on the MRI table comfortably and they will ensure that the position is optimal for getting good quality MRI images. There will be some noises during MRI scanning, for which we will be given earplugs in most MRI centres to reduce the noises.
