There are a lot of questions when it comes to MRI’s. What are they? How do they work? Why do they make such weird noises? How much radiation will I be exposed to? It’s totally normal for patients to have questions about their imaging procedures, and as medical professionals who practice in the world of diagnostic imaging, we field questions about MRI’s on a daily basis. We’ve noticed, however, that there’s also a lot of misinformation out there about MRI technology and what happens during the procedure.
Today we’re setting the record straight about two of the most common MRI myths and misconceptions that patients struggle with:
Myth #1: All MRI Machines Are Created Equal
We cannot begin to stress how completely 100% incorrect this statement is. Think of your MRI results as a picture and the machine itself as a camera, because that’s essentially what it is. In order to determine whether there’s anything wrong, a clear and high quality image must be produced. In order to produce a sharper, higher quality image, you’ll need a higher quality camera. Anyone who’s used a cheap point and shoot camera and then picked up a DSLR can tell you that not all cameras are the same, and likewise not all MRI machines are the same. The better the image needed, the nicer the machine has to be.
Myth #2: People Who Have Had Joint Replacement Can’t Get An MRI
With MRI’s, there’s a lot of emphasis placed on the fact that you have to completely remove any metal from your body before undergoing the procedure. Piercings, belts, zippers on jeans, etc. – anything that’s remotely metal must be removed before someone can enter the MRI machine because of the strength of the magnets. This causes concern for people who have had procedures such as joint replacements, where the implanted devices could contain metal.
Despite what many people think, in most cases medical devices such as these are not affected by the magnetic field of the MRI machine and should not provide a problem when scanned. Patients undergoing MRI’s who have had medical implants should discuss this with their doctor prior to the MRI procedure just to make sure that it is safe for them to proceed, but for the majority of cases this shouldn’t cause an issue.
If you’ve fallen victim to either of these myths, don’t worry you aren’t alone! Just remember to keep this information in mind before you schedule an MRI. Make sure that the facility you go to has a quality machine (like ours!) and that you discuss any prior medical procedures with the doctor.
