Myth: You can get radiation exposure from MRIs.
Fact: Ionizing radiation is not a concern with MRI scans because they use magnetic power and radiofrequency to translate information into images -- no ionizing radiation is used.
Myth: Open MRIs are as good as closed.
Fact: A common complaint with MRIs is the claustrophobic feeling experienced when entering the chamber. Low-field, open MRIs were created to combat this feeling. Though you can still get great images from an open-bore magnet, having a standard MRI is the option for the best diagnosis, especially for spine, head, and smaller anatomy such as the wrist and hand.
Myth: I can't have an MRI because I've had joint replacement.
Fact: The majority of medical devices used to care for patients can be safely scanned. This includes such common devices such as orthopedic joint replacements and implanted hardware used to treat fractures. Be aware, though, that the technologist will need to know information about the implanted device, such as the make, year and location on the body.
Myth: People with tattoos can't get MRIs.
Fact: While some tattoo ink contains traces of metal, most tattoos are safe in an MRI scanner. Inform the radiographer if you have a tattoo, and speak up immediately if you feel any discomfort or heat in your tattoo during the scan. This includes permanent makeup, as well.
Myth: People with artifacts lodged in their body (e.g. pellets, bullets, shrapnel) cannot receive an MRI.
Fact: Actually, it is very common to have an MRI with foreign structures lodged in the body. The concern lies more in the location of the object and the material it's made of. Be sure to inform the radiographer of any objects that might be lodged in your body, regardless of how long they have been there.
Myth: I can't get an MRI because I'm pregnant.
Fact: While safety for the mother and unborn baby is a priority, there are certain times and circumstances that an MRI might be warranted for a pregnant woman. Because most MRIs would be performed on the mother, rather than the baby, they are safer to use during pregnancy than x-rays.
Myth: The MRI will ruin my hearing.
Fact: The MRI does produce mechanical banging which can be loud, but it rarely will exceed the safety levels of 100 decibels or more during a scan. In terms of noise level, the best way to think of an MRI is to liken it to that of a loud rock concert. For most patients, ear plugs and some background music delivered to you via headphones will help pass the time and help you get through the scan.
