Some people may view MRI's as mysterious, loud, and even scary when they first think of this diagnostic imaging tools. While they present many questions, MRI's often come with numerous common misconceptions about the scanners used and how it may affect the patients undergoing the scan. We're here to debunk these common MRI myths once and for all.
Myth: All MRI machines are created equal.
We cannot stress how incorrect this statement is. Think of your MRI results as a picture, and the machine as the camera. In order to determine a diagnosis of the part being scanned, 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. For ailments that require better imaging, more advanced MRI machines are needed to create a better image.
Myth: People who have had joint replacement can’t get an MRI.
Before getting an MRI, there’s often an emphasis placed on completely removing any metal on the body including piercings, belts, and zippers on jeans. Anything that’s metal must be removed before someone can enter the MRI machine because the metal in the magnets can interfere with the scanning process. This causes concern for people who have had procedures such as joint replacements done where the implanted devices could contain metal. For the most part, medical devices such as these are not affected by the magnetic field of the MRI machine and do not create a problem when scanned. Patients undergoing MRI’s who have had medical implants should discuss the scan with their doctor prior to the MRI procedure to ensure that it is safe.
Myth: MRI's are painful and emit dangerous radiation.
This couldn't be farther from the truth. MRI's are completely painless and non-invasive. In comparison to other diagnostic imaging scans, MRI technology does not rely on x-ray which means no harmful radiation for our patients. While they may be long and noisy, the procedure ensures the patient is completely safe.
