Magnetic Resonance Imaging Safety: What to Expect The MRI is quickly becoming the most popular body scan available today. While the MRI has many perks, one is still left to ask the question, but is it safe? The short answer is yes. Having an MRI done is very safe, but it would still do one good to discuss in general magnetic resonance imaging safety. The biggest cause for concern is the giant magnets used in the MRI process. Prior to having an MRI done a patient must remove any and all metal objects from their person. Before any patient, nurse, or doctor is allowed into the scanning room, he or she is thoroughly screened for metal objects that may reside inside their person that would make it very dangerous for them to be in the presence of a very strong magnetic field. Examples of this would be metallic fragments in the eye of a patient. Even if they have been there for many years and have caused the patient no major discomfort, they could in the presence of the MRI machine moved about and cause permanent eye damage or even blindness. If someone has a pacemaker, they are not allowed to go through a MRI scan or even enter the room, as the magnet may cause the pacemaker to malfunction. Other dangers include aneurysm clips in the brain. The magnet in the MRI machine can cause the clips to move, causing them to tear the artery they are repairing. There are also some dental implants that are magnetic. Metal staples usually do not pose a problem, especially if they have been in the body for several weeks, as the scar tissue built around them will hold them firm in place. Even any patient is found to have a metallic object in their body; they are given a through evaluation to make sure it is safe to scan them. They are sometimes turned away because it would simply just be too dangerous to complete the scan. In reference to magnetic imaging safety, there are currently no known biological hazards to humans from being exposed to these magnetic fields. It is both safe and efficient! | ||||||||||||||||||||||||||||||||||||||||
