Necessary Preparation Work Before MRI Scan
Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to visualize internal structures in a detailed manner. MRI uses Nuclear magnetic resonance (NMR) to picture nuclei of atoms inside the body. Preparation work before a MRI scan is hassle free and it is mostly used for orthopaedic injuries. It is extremely easy and there is no restriction except for one thing - metallic objects. Metallic objects cannot be brought into the MRI room and that includes metallic products you are carry such as your jewellery and even metal implants in the body. If you have metal implants, you need to let your doctor know and he will advise accordingly. It is also advisable to go for the MRI scan without make up if you are a female. This is due to some cosmetics containing traces of metallic elements which may interfere with the MRI scan. It is also important that you declare your medical history to the doctor truthfully before the MRI scan so that they will know exactly what implants you have in your body and whether they could be metallic.

Generally, you will need to arrive at the hospital around 30 minutes before the scan.

You will be provided with an assistance handheld device that you should use if you feel any discomfort during the scan. There will also be a speaker which the technologist will use to talk to you.

You will hear lots of loud noises and this is due to the changes in the magnetic field. MRI is generally a safe process but patients who are claustrophobic or those with metallic implants in crucial parts of their body are not allowed to undergo a MRI scan due to safety constraints.
