Magnetic resonance imaging (MRI) has been part of routine medical practice for years. The big tubes produce fascinating images. No wonder that MRI is seen as the crowning glory of diagnostics. But how exactly does it work? What’s so special about it? We answer twelve questions to give a better idea.
1) What does an MRI machine do?
2) What are MRIs used for? And what not?
3) Is MRI better or worse than computer tomography (CT)?
4) Does MRI involve contrast agents?
5) How exactly is an MRI image produced?
6) Can you explain further how it works?
7) So this is what produces the precise images?
8) How strong are these MRI magnets? Aren’t they dangerous?
9) Are there patients who can’t have an MRI scan?
10) On the subject of claustrophobia: Why do the tubes have to be so narrow?
11) Do MRI machines always have to be kept in a basement?
12) Last question: an MRI scan can be incredibly loud. It makes creaking and sawing noises, and sometimes there’s a kind of knocking like a tumble dryer that’s unevenly loaded. Why?
The statements by Siemens Healthineers customers described herein are based on results that were achieved in the customer’s unique setting. Since there is no “typical” hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption) there can be no guarantee that other customers will achieve the same results.
